The Siemens 3VU2932-4DF0 is a shunt release rated for 110/120V AC, designed as an accessory for the 3VU2.4 and 3VU2.5 series of motor protective circuit breakers. It provides remote tripping capability — when the coil is energized, it mechanically releases the breaker's latch, opening the main contacts. This is the standard method for integrating an emergency-stop or supervisory control signal into a motor branch circuit.
Integration note
The shunt release mounts directly onto the 3VU2.4 or 3VU2.5 breaker body — no additional wiring space or DIN-rail real estate beyond the breaker's own footprint. The coil draws from the control circuit, so verify the 110/120V AC supply is present and fused per the breaker's terminal rating.
