It sits on the left side of the breaker, wired to a control voltage, and when energized it mechanically trips the breaker independent of any overload or short-circuit condition. That makes it the part you spec when a safety circuit, an E-stop button, or a PLC digital output needs to kill motor power remotely without waiting for the thermal overload to heat up. The coil accepts 220…240 V AC or 220…250 V DC — dual-rated, so it works on either supply without a separate rectifier. The front is finger-safe per IEC 60529 (IP20), meaning an operator reaching into the panel from the front cannot contact live terminals. That matters for panel builders who need to keep the IP20 rating on the enclosure door open. The part is at a current lifecycle stage.","metaTitle":"Siemens 3RV1952-1EF0 SIRIUS Shunt Release, 220-240 V AC / 22","metaDescription":"Siemens SIRIUS 3RV1952-1EF0 shunt release for size S00/S0 circuit breakers.
