It carries 2 normally-open (NO) leading auxiliary contacts, meaning the auxiliary contacts change state slightly ahead of the main trip action — useful for signaling or interlocking in a safety circuit. Screw-type terminals on the auxiliary and control circuit accept standard wiring — no special crimp tool needed. The break time is a maximum of 20 ms, fast enough to protect downstream equipment during a voltage sag. This release snaps onto the front of a 3RV2 motor circuit breaker. The 19 mm width matches the breaker's modular pitch, so it doesn't eat extra DIN rail space. Depth is 68 mm, height 90 mm — check your enclosure depth if you're retrofitting into a shallow gland plate. The 690 V rated value covers most 400 V line-to-line systems with margin.","metaTitle":"Siemens 3RV2922-1CV0 SIRIUS Undervoltage Release, 400 V AC/5","metaDescription":"Siemens 3RV2922-1CV0 SIRIUS undervoltage release for 3RV2 motor circuit breakers. 400 V AC/50 Hz, 2 NO leading auxiliary contact, screw terminals.
