3RV motor starter protectors

SIRIUS 3RV motor starter protectors are compact, current-limiting circuit breakers up to 100 A for motor or starter protection. They guarantee safe disconnection in the event of a short circuit and protect loads and the system from overload. They are also suitable for normal switching duty with loads that have a small number of switching operations as well as for reliable isolation of the equipment from the supply system. We also offer: Circuit breakers in special versions, e.g. for plant protection - also according to UL/CSA, for transformer protection or overload relay functions.

The main circuit wiring can be significantly reduced by using different infeed possibilities, such as the associated SIRIUS 3RV infeed system, the three-phase busbar system, or the 8US busbar system.
