Siemens Circuit breaker 3RV2121-4DA10 1 pc.

Circuit breaker size S0 for motor protection, Class 10 with overload relay function A-trip 18...25 A N-trip 325 A screw connection standard switching capacity. SIRIUS 3RV2 circuit breakers for motor protection with overload relay function ensure safe disconnection in case of short circuits and protect consumers and systems from overload, as well as providing safe isolation of the system from the power supply. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, and are naturally suitable for IE3/IE4 motors and for switching direct current. Worldwide approvals (e.g., IEC and UL/CSA) and applications in explosion-prone environments (ATEX or IEC Ex) are standard. Variants are available for motor protection (also with overload relay function), system protection, short circuit protection of starter combinations, transformer protection, as main and emergency stop switches, and for use in IT networks. They come with screw or spring-loaded connections for quick, maintenance-free, and vibration-resistant connections, and optionally with built-in auxiliary switches. The extensive accessories, such as auxiliary switches, auxiliary relays, signaling switches, etc., are uniform across all sizes. The use of various power supply options, such as the associated SIRIUS 3RV29 supply system, significantly reduces the wiring of the main power circuit. The 3RV2 circuit breakers replace the proven 3RV1 series. Simple, efficient, always up to date - the SIRIUS system modular design.
