It allows remote tripping from a control system or emergency-stop circuit. Rated for 220...240 V AC and 220...250 V DC, so it covers the common European and North American control voltages in one part. The AC and DC ranges overlap, but the DC upper limit is 250 V — watch that if your DC bus runs at 270 V nominal; this release is not rated for that. Lifecycle stage is current. No successor or phase-out date is listed. For a BOM calling out 3RV1982-1EF0, this is the direct fit.","metaTitle":"Siemens 3RV1982-1EF0 SIRIUS Shunt Release, 220-240 VAC / 220","metaDescription":"Siemens 3RV1982-1EF0 SIRIUS shunt release for size 3RV1.6/7/8. 220-240 VAC, 220-250 VDC.
