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.
Highlights at a glance
What does biowaste have to do with our circuit breakers?
Quite simply: the housings of the SIRIUS 3RV2 circuit breakers are largely made of a particularly sustainable plastic. In its production, all fossil raw materials were replaced by recycled organic waste. Of course, without compromising on quality and performance.

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.
Protection against unauthorized access
The integrated locking device protects against unauthorized access, thus ensuring trouble-free operation. This protective device is installed as standard in every SIRIUS 3RV2 motor starter protector.
Simple installation
Sizes S00 and S0 to 40A are equipped for particularly flexible assembly by means of the screw and spring-type terminals. Thanks to appropriate link modules, motor starter protectors in these sizes can be quickly and simply connected to SIRIUS switching devices.
All relevant sizes
Being available in sizes S00, S0, S2 and S3 as well as in different versions means that the motor starter protectors/circuit breakers cover all tasks involved in the protection of motors, starters, transformers and UL 489 applications.
Accessories for the circuit breaker - Door-coupling rotary operating mechanisms
Motor starter protectors/circuit breakers with a rotary operating mechanism can be mounted in a control cabinet and operated externally by means of a door-coupling rotary operating mechanism. When the cabinet door with motor starter protector is closed, the operating mechanism is coupled. When the motor starter protector closes, the coupling is locked which prevents the door from being opened unintentionally.
