Worldwide approvals (e.g. IEC and UL/CSA) and applications in potentially explosive atmospheres (ATEX or IEC Ex) are a matter of course.Device 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 OFF switches and for use in IT networks. They are available with screw or spring-cage connection for fast, maintenance-free and vibration-proof connection, and optionally with built-in auxiliary contacts.The comprehensive range of accessories, such as auxiliary contacts, auxiliary releases, signaling switches, etc., is uniform for all sizes. The use of various power feed options, such as the associated SIRIUS 3RV29 feed system, considerably reduces the main circuit wiring.The 3RV2 circuit-breakers replace the proven 3RV1 series.Simple, efficient, always up-to-date - the SIRIUS modular system. , EAN: 4011209766785.
