More about selecting SIRIUS 3RV parts
Use of SIRIUS 3RV parts
SIEMENS SIRIUS 3RV motor circuit breakers are used to protect motor outputs. Our range also includes undervoltage trip units, indicator lights, control components and connection accessories.
Part selection and replacement
The SIRIUS 3RV range comprises motor circuit breakers and their separate accessories. When replacing components, distinguish between the circuit breaker, auxiliary release, control unit, indicator light and connecting busbar. The replacement part must correspond to the size of the circuit breaker and the design of the entire assembly. For undervoltage trip units, also check the voltage and frequency; for busbars, check the pitch, the number of circuit breakers to be connected and the connection method.
