circuit breaker frame size S3 for motor protection, CLASS 10 release A 75...93 A release N 1300 A screw terminal standard switching power SIRIUS 3RV2 circuit breaker For motor protection for safe disconnection in the event of a short circuit and for overload protection of the users and the system as well as for the safe separation of the system from the mains.\nThe compact and tropicalized automatic switches are optimized, thanks to their low thermal dispersion, for use in starters, naturally also for IE3/IE4 motors and in equal measure for direct current switching. International approvals (e.g. IEC and UL/CSA) and versions for applications in potentially explosive areas (ATEX or IEC Ex) are obviously available.\nDevice variants for motor protection are available (also with overload relay function ), system protection, short-circuit protection of combined starters, transformer protection. as a main and EMERGENCY STOP switch and for use in IT networks. They are available with screw or spring-loaded terminals for quick, maintenance-free and vibration-resistant connection as well as optionally with a built-in auxiliary switch block.\nAll accessories such as e.g. auxiliary contact blocks, auxiliary releases, signaling contact blocks etc. they are uniformly suitable for all construction sizes. The various power supply options, such as the SIRIUS 3RV29 power supply system, significantly reduce the wiring of the main circuit.\nThe 3RV2 circuit breakers replace the proven 3RV1 series.\nSimple, efficient, always up-to-date - the SIRIUS modular system.
