This undervoltage release snaps onto the side of the 3RV1 circuit breaker, occupying no additional DIN rail space. The 24–30 V AC/DC control coil is wired in series with the emergency-stop or undervoltage monitoring circuit — when the control voltage disappears, the release mechanically forces the breaker to trip. Verify the coil voltage matches your control transformer tap before wiring.","metaTitle":"Siemens 3RV1982-1AA0 SIRIUS undervoltage release, 24–30 V AC","metaDescription":"Siemens SIRIUS 3RV1982-1AA0 undervoltage release, 24–30 V AC/DC, for 3RV1.6/7/8.
