The Siemens 3RV1982-1EA0 is a SIRIUS shunt release, a remote-trip accessory designed for the 3RV1.6, 3RV1.7, and 3RV1.8 sizes of the 3RV1 motor starter protector family. It accepts a 24...30 V AC/DC control signal to trigger an instantaneous trip, allowing an emergency-stop circuit or a remote PLC output to drop the load without a manual panel visit.
Integration Note
This shunt release mounts directly into the accessory slot on the front of a 3RV1.6, 3RV1.7, or 3RV1.8 motor starter protector. No additional wiring space or DIN-rail real estate is consumed beyond the base breaker's footprint. The 24...30 V AC/DC coil is polarity-insensitive for DC, simplifying control-wiring hookup.
Compliance
The part carries a Substance Prohibitance compliance date of 05/01/2012, indicating it meets RoHS-like substance restrictions effective from that date. As a Siemens SIRIUS component, it is designed for use in IEC and UL 489 / UL 508 listed panel assemblies when paired with the appropriate 3RV1 base breaker.
