It fits the 3VA1 and 3VA20 through 3VA25 frame sizes.
The release measures 65.1 mm high, 25.7 mm wide, and 28.8 mm deep. It snaps into the accessory slot on the breaker — no DIN-rail footprint of its own. The three accessory slots on the 3VA frame accept this release alongside other auxiliaries; plan the slot assignment before panel wiring.
It is an undervoltage release that trips a Siemens 3VA1 or 3VA20–3VA25 circuit breaker when the control voltage falls below the dropout threshold, protecting downstream equipment from brownout conditions.
