Circuit breaker size S00 for starter combinations with a rated current of 12.5 A and a N-trip current of 163 A. The screw connection offers standard switching capacity. The SIRIUS 3RV2 circuit breakers are designed for starter combinations to safely protect consumers in case of short circuits and ensure a safe disconnection from the network. These compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation and are suitable for both IE3/IE4 motors and for switching direct current.

Global approvals, such as IEC and UL/CSA, as well as applications in explosion hazard areas (ATEX or IEC Ex), are standard. 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.

The devices are available with screw or spring-loaded connections for a quick, maintenance-free, and vibration-resistant connection, optionally with an integrated auxiliary switch. The comprehensive accessories, such as auxiliary switches, auxiliary trip devices, signaling switches, etc., are uniform across 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.
