SIEMENS has discontinued the 3VU2 circuit breakers for motor protection, as well as all accessories for the product.
The Siemens 3VU2 moulded-case circuit breakers had nominal currents from 100A to 630A. They were mainly used in motor feeders with voltages of 690V.
According to Siemens, the SIRIUS 3RV1 moulded-case circuit breakers up to 800A provide a suitable swap replacement for the 3VU2 circuit breakers.
The SIRIUS 3RV1 circuit breakers are employed with voltages exceeding 500V. For lower voltages, load feeders should be assembled with the SENTRON 3VL circuit breakers.
