The Siemens 3VU9132-0AB58-0RE0 is a shunt release accessory for the 3VU13 and 3VU16 switch ranges, designed to trip the switch on application of a control voltage. It operates on AC 50Hz at 415V, making it a direct-fit remote-trip component for those specific switch frames.
This shunt release mounts into the accessory slot on the 3VU13 or 3VU16 switch body. It is a critical spare for any panel using those Siemens motor-protective switches with remote-trip capability — a missing shunt release means the switch cannot be tripped from a PLC or emergency-stop circuit.
