Siemens SIEM circuit breaker

Circuit breaker size S00 for starter combinations with a rated current of 16 A and a N-trip current of 208 A. These screw connection standard capacity circuit breakers SIRIUS 3RV2 are designed for starter combinations to safely protect consumers from short circuits and ensure a safe disconnection from the power supply. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, also suitable for IE3/IE4 motors and for switching direct current. They have worldwide approvals (e.g., IEC and UL/CSA) and are suitable for applications in explosive environments (ATEX or IEC Ex).

There are device variants available for motor protection (also with overload relay function), plant protection, short circuit protection for starter combinations, transformer protection, as main and emergency stop switches, as well as for use in IT networks. These switches are available with screw or spring-loaded connections for a quick, maintenance-free, and vibration-resistant connection, optionally with a built-in auxiliary switch.

The comprehensive accessories, such as auxiliary switches, auxiliary trip devices, and signaling switches, are standardized for all sizes. The use of various energy supply options, such as the associated SIRIUS 3RV29 supply system, significantly reduces the main circuit wiring. The 3RV2 circuit breakers replace the proven 3RV1 series. Simple, efficient, always up to date - the SIRIUS system modular concept.
