Product Details
Siemens Motor Protection Circuit Breaker, 690V Rated Voltage, Screw Terminals - SIRIUS Series - 3RV2021-1EA10
Cut power to your equipment in a tick with this motor protection circuit breaker from Siemens. It has a rotary switch on the front, so you can manually turn the power on and off. This is lockable, giving you peace of mind when you're carrying out servicing and repairs to downstream devices. A magnetic short-circuit trip and a thermal overload release automatically break the circuit when electrical faults occur to prevent damage to motors. The unit works with both single-phase AC and three-phase DC motors for convenience. Use it alongside your size S0 and S00 contactors to reliably boost operational safety in heavy plant environments.
