Siemens Circuit breaker 3RV2042-4MB10 1 pc.

Circuit breaker size S3 for motor protection, CLASS 20 A trip unit 80...100 A, N trip unit 1300 A, screw connection with increased switching capacity of 100 kA. SIRIUS 3RV2 circuit breakers for motor protection 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 grid. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, and they are naturally suitable for IE3/IE4 motors and equally for switching direct current. Global approvals, such as IEC and UL/CSA, and applications in explosion-risk 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 terminals for quick, maintenance-free, and vibration-resistant connections, and optionally with an integrated auxiliary switch. The comprehensive accessories, such as auxiliary switches, auxiliary trip units, 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 main circuit wiring. The 3RV2 circuit breakers replace the proven 3RV1 series. Simple, efficient, always up to date - the SIRIUS system modular design.
