The LSIG suite means this breaker covers overload, short-circuit, and ground-fault in one package — typical for a motor feeder where you need coordinated protection against both phase and ground faults without a separate relay. ## Accessories and auxiliary wiring The UVR drops the breaker on loss of control voltage — standard for safety circuits where a downstream contactor also needs to drop. Auxiliary switches and the alarm contact give the PLC a status read without tapping the load terminals.","metaTitle":"Siemens 3VA2140-7MQ32-0DH0 Circuit Breaker, 40A, 110kA @ 415","metaDescription":"Siemens 3VA2140-7MQ32-0DH0 IEC frame 160 circuit breaker, 40A, 110kA breaking capacity at 415V, motor protection ETU860M, LSIG.
