Circuit breaker size S0 for system protection without phase failure protection A- trigger 2.8... 4 A N- trigger 52 A spring connection Standard circuit breaker SIRIUS 3RV2 for system protection for the safe shut-off of short circuit and protection of consumers and system against overload, as well as for the safe separation of the system from the network. The compact and climate-resistant circuit breakers are optimized by their low waste heat for use in consumer branches, of course also for IE3 / IE4 engines. Worldwide approvals (e.g. IEC and UL / CSA) and applications in potentially explosive applications (ATEX or IEC Ex) are natural. The range of devices available for engine protection (also with overload relay function), system protection, short-circuit protection of starter combinations, transformer protection, as main and NOT switch and for use in IT networks. They are available with screw or spring connection for a fast, maintenance-free and brittle-proof connection, and optionally with built-in auxiliary switch. The comprehensive accessories, such as auxiliary switches, auxiliary triggers, reporting switches, etc., are uniform for all sizes. The use of different energy supply possibilities, such as the associated SIRIUS 3RV29 feed system, significantly reduces the main current circuit wiring. The 3RV2 circuit breakers release the proven 3RV1 series. Simple, efficient, always up to date - the SIRIUS system kit.
