The 3VU2932-4DP0 is a shunt release rated 110/127V AC, designed as an accessory for the Siemens 3VU2.4 and 3VU2.5 motor protective switch series. It provides remote tripping capability — when voltage is applied to the release coil, it mechanically trips the breaker, allowing a control system or emergency-stop circuit to open the motor circuit without an operator at the panel.
Mounts directly into the 3VU2.4 or 3VU2.5 breaker's accessory slot — no additional wiring space needed inside the panel. The coil draws power from a separate 110/127V AC control circuit; verify the control transformer sizing if multiple releases share the same supply.
