Circuit breaker 20 A rated current 20 A, N-release 260 A, for starter combination, screw connection, standard switching capacity Circuit breaker SIRIUS 3RV6 for starter combinations for the reliable protection of the loads in the event of a short-circuit and for the safe isolation from the network. Thanks to their low heat loss, the compact and climate-resistant circuit breakers are optimized for use in load feeders and equally for the switching of direct current. Worldwide approvals (e.g. IEC and UL/CSA) are a matter of course. Device versions are available for motor protection (also with overload relay function), plant protection,short-circuit protection of starter combinations, transformer protection, as main and EMERGENCY OFF switches and optionally with integral auxiliary switch. The comprehensive range of accessories, such as auxiliary switches, auxiliary releases, signaling switches etc. is standardized for all sizes. The use of different energy infeed options, such as the associated SIRIUS 3RV29 infeed system, considerably reduces the main circuit wiring. Simple, efficient and always up to date - SIRIUS modular system.
