Size S2 circuit breakers for motor protection, CLASS 10 A trip units 54...65 A N trip units 845 A Screw connection Standard switching capacity SIRIUS 3RV2 motor starter protectors for motor protection for safe shutdown in the event of a short circuit and protection of the consumer 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
