Motor Protection Circuit Breaker

SIRIUS 3RV2 circuit breakers The availability of machines and plants is a precondition for maximum productivity. Machines and plants should therefore be reliably protected against overload from the power supply system. In the event of a failure, motor starter protectors quickly disconnect the equipment from the supply, thus preventing expensive damage. The SIRIUS 3RV2 motor starter protector provides ideal protection. Take advantage of the benefits of SIRIUS 3RV2 motor starter protectors SIRIUS 3RV2 motor starter protectors reliably intervene in three different cases. In the event of a short-circuit – current >13 times the rated current – the short-circuit releases isolate the faulty load feeder from the power supply within only a few milliseconds. Greater damage, caused by fires for example, can thus be avoided. The motor starter protector features a lockable operating mechanism for manual closing/opening, to be used for example while carrying out repairs. The overload release isolates the load from the power supply if it is loaded with an overcurrent for a certain time. Tripping is based on a specific time-current characteristic. This prevents possible damage to the load and the system. The overload release also trips in the event of phase failure or extreme phase unbalance
