Auxiliary switches can also be mounted on 5TE8 flush-mounting circuit breakers and 5SG71 MINIZED switch disconnectors. Auxiliary switches (AS) The auxiliary switch (AS) always signals the contact position of the miniature circuit breaker, regardless of whether the miniature circuit breaker was tripped manually or as the result of a fault. An additional version is also available for the switching of small currents and voltages for the control of programmable control systems (PLCs) acc. to EN 61131-2. The auxiliary switch with test button enables the testing of control circuits without the need to switch the miniature circuit breaker. Fault signal contacts (FC) The fault signal contact (FC) signals the automatic tripping of the miniature circuit breaker in the event of a fault, such as an overload or a short circuit. If the fault signal contact is activated, the contact position does not change if the miniature circuit breaker is tripped manually. Fault signal contacts with TEST and RESET buttons enable the testing of control circuits without the need to trip the miniature circuit breaker. The red RESET button integrated in the handle also indicates the automatic tripping of the MCB. The signal can be acknowledged manually using the RESET button. Selector switch position: OFF: The remote controlled mechanism is switched off, blocked mechanically and can be sealed and/or locked. RC OFF: Only manual operation is possible. RC ON: Both manual and remote operation are possible. In the event that a device is tripped by a fault (RC units, miniature circuit breakers), the handle of the basic device and remote controlled mechanism switches to the OFF position. The operator must then acknowledge the tripping by resetting the remote controlled mechanism (OFF command) before it can be reactivated. This serves the safety of the installation or to protect personnel during maintenance work. In an RC unit/miniature circuit breaker combination, the RC unit is switched on asynchronously, i.e. prior to the miniature circuit breaker. The RC units for 5SY and 5SP4 can be switched ON via the MCB handle jumper using the supplied actuator attachment. There is no need to switch off the RC unit via the remote controlled mechanism as the MCB contacts ensure disconnection of the electrical circuit. The switching frequency is max. 2 actuations per minute. If this actuation frequency is exceeded it may cause internal tripping of the remote controlled mechanism as a protection against possible overload. In this case, the remote controlled mechanism must be switched OFF at the function selector switch and not switched back on again for at least 5 minutes. More additional 5ST3 ... components, such as AS, FC, ST and UR, can be added to the right-hand side of the remote controlled mechanism in line with the Siemens mounting concept. Shunt trips (ST) RC units Shunt trips are used for the remote tripping of a miniature circuit breaker. RC units can be combined with miniature circuit breakers of characteristic A, B, C and D. They then form a combination of RCCB and MCB for personnel, fire and line protection. The combinations can be tailored to meet individual requirements. Undervoltage releases (UR) Undervoltage releases are integrated (e.g. in EMERGENCY-OFF loops), thus ensuring that the MCB trips in the event of an emergency, which, in turn, ensures disconnection of the control circuit according to EN 60204. In the event that the voltage is interrupted or too low, it also trips, i.e. prevents activation of the MCB. Remote controlled mechanisms (RC) Remote controlled mechanisms are used for the remote ON/OFF switching of miniature circuit breakers and the remote ON switching of RC units, as well as the local manual switching of these devices. A blocking function permits maintenance work. In the event that a miniature circuit breaker or RC unit is tripped, an acknowledgment must be carried out prior to switching back on. The remote controlled mechanism has an operating mode selector switch with the functions: "Locked", "Manual" and "Remote Switching". 12 Siemens * 10/2015 For information on RC units, see chapter "Residual Current Protective Devices / Arc Fault Detection Devices (AFDDs)" in Catalog LV 10.

Busbars in 10 mm2 and 16 mm2 versions are available. With bars that can be cut to length, the 5ST37 busbar system can be tailored to any requirements. The extremely flexible 5ST36 busbar system with fixed lengths also enables installation in any length as the busbars can be overlapped. No further need for time-consuming tasks, such as cutting, cutting to length, deburring, cleaning of cut surfaces and mounting of end caps. Any free pins on the busbars can be made safe by covering with touch protection.

An overcurrent protection device is required for each reduction of the conductor cross-section. This produces a series connection staggered according to rated currents, which should, if possible, be "selective". Selectivity means that, in the event of a fault, only the protective device that is directly next to the fault in the current circuit is tripped. This means that current paths in parallel can maintain a power flow. In the case of miniature circuit breakers with upstream fuses, the selectivity limit depends largely on the current limitation and tripping characteristics of the miniature circuit breaker and the melting I2t value of the fuse. This produces different selectivity limits for miniature circuit breakers with different characteristics and rated breaking capacity. The following tables provide information on the short-circuit currents up to which selectivity exists between miniature circuit breakers and upstream fuses according to DIN VDE 0636-2. The values specified in kA are limit values that were determined under unfavorable test conditions. Under normal practical conditions, you can often expect considerably better values, depending on the upstream fuses. In the event of a short-circuit, there is selectivity between the 5SY4, 5SY7, 5SP4, 5SJ4...-.HG.. miniature circuit breakers and melting fuses according to DIN VDE 0636-2 up to the specified values in kA.

circuit breakers According to DIN VDE 0100-410, in order to protect against dangerous leakage currents in the TN system, the crosssections of the conductor, or its distance from the protective device,

The max. voltage per pole must not exceed 72 V DC. A multiple of this can be achieved through series connection of two or more poles depending on the circuit, e.g. max. 144 V DC through series connection of two poles.

The maximum voltage for 5SY5 UC devices is 250VDC per pole. The series connection of individual poles enables 4-pole devices (for example) to be used for up to a maximum of 1000 V DC. The arcing chamber area of the 5SY5 miniature circuit breakers is equipped with additional permanent magnets to support the positive quenching of the electric arc. This is why the polarity of the breaker is marked. it is essential to pay attention to the conduction direction when connecting the conductor. Suitable precautions should be taken during plant configuration to ensure there can be no polarity reversal in DC operation (e.g. photovoltaic plants).

This is of particular importance to European exporters of electrical switchgear assemblies and equipment for machines who export to the USA, as their products will only be accepted if they meet the relevant UL standards. A wide range of low-voltage circuit protection devices from Siemens comply with UL standards and are therefore suitable for implementation worldwide in both IEC/EN and UL applications within the framework of their specified use. Miniature circuit breakers certified to UL 489 permit use as an all-round solution for protection tasks in distribution boards, control cabinets and control systems to UL 508A as "branch protectors". In particular, they are also approved for the protection of electrical circuits in heating, ventilating and cooling systems (HVAC), as well as for DC applications up to 60 V/125 V. This covers a wide range of protection tasks, in residential and non-residential buildings, as well as in industry. The tripping characteristics B, C and D to EN/IEC 60898-1 have been adapted so that they fall in the permissible tripping range according to UL 489, as well as for applications at 25 C and 40 C. This means that the devices are approved for use according to both standards. The enclosure dimensions of the devices correspond to DIN format. This means that the device series are suitable for universal use worldwide according to IEC or UL standards. The key difference between the three device series is their application in different power supply systems. * 5SJ4...-.HG40: 240/120 V AC, 1-pole, "same polarity only" * 5SJ4...-.HG41: 240 V AC, 1-, 2- and 3-pole * 5SJ4...-.HG42: 480Y/277 V AC, 1-, 2- and 3-pole The terminals are suitable for "field wiring". This means that the devices can be installed not only in factory-built distribution boards and control cabinets, but also on-site in a customer system. Using this mounting concept, all 5ST3. . .-. HG additional componentscan be combined with miniature circuit breakers of the 5SJ4...-.HG range. The auxiliary switch (AS) signals the contact position. In the event of a fault, the fault signal contact (FC) signals the automatic tripping of the MCB as well as the contact position. Shunt trips (ST) are used for the remote tripping of miniature circuit breakers. Captive metal brackets on the additional components ensure fast mounting on the devices. Single, two and three-phase busbars in 3 lengths with 6, 12 or 18 pins are available as accessories for all device series for "field wiring". The infeed is via connection terminals, which are available in two versions, for direct infeed at either the busbar or the miniature circuit breakers. Pins that are not required can be covered with touch protection covers.
