Siemens 3RV2021-4BA10 Circuit breaker 1 pc(s) Adjustment range (amperage): 13 - 20 A Switching voltage (max): 690 V AC
Size S0 circuit breakers for motor protection, CLASS 10 A trip units 13...20 A N trip units 260 A Screw connection Standard switching capacity SIRIUS 3RV2 circuit breakers for motor protection for safe shutdown in the event of a short circuit and protection of the consumers and system against overload, as well as for safe separation of the system from the mains.The compact and climate-proof circuit breakers are optimized for use in consumer feeders due to their low heat dissipation, naturally also for IE3/IE4 motors and equally for switching direct current. Worldwide approvals (e.g. IEC and UL/CSA) and applications in hazardous applications (ATEX or IEC Ex) are a matter of course.Device versions are available for motor protection (also with overload relay function), system protection, short-circuit protection of starter combinations, transformer protection, as main and EMERGENCY-OFF switches and for use in IT networks. They are available with screw or spring-type terminals for a fast, maintenance-free and vibration-proof connection, and optionally with integrated auxiliary switches.The comprehensive accessories, such as auxiliary switches, auxiliary releases, signaling switches, etc., are uniform for all sizes. The use of various power supply options, such as the associated SIRIUS 3RV29 infeed system, considerably reduces the main circuit wiring.The 3RV2 circuit breakers detach the proven 3RV1 series.Simple, efficient, always up-to-date - the SIRIUS modular system.This text is machine translated.
