Motor Protection Circuit Breaker with Class 30 Electronic Trigger
The Siemens 3VU2032-0AL60 is a motor protection circuit breaker rated for load feeders up to 690 V, with an adjustable current range of 50–100 A and an electronic trigger set to 13 times the set current (13 x I_in). The Class 30 electronic trigger means the breaker allows a 30-second overload trip delay at 7.2 x I_in, matching the thermal time constant of large motors and high-inertia loads — common on pumps, compressors, and conveyors where nuisance tripping on start-up must be avoided. Snaps onto DIN rail in a standard control panel enclosure; the 50–100 A range covers a broad swath of medium-frame motor sizes without needing a separate overload relay.
