The adjustable instantaneous trip (Ii) ranges from 5 to 15 times In, so you can dial it in for motor inrush without nuisance tripping on a pump or conveyor start. For a 480 V or 600 V panel, the Icu will be lower; check the selectivity tables if you're coordinating with a downstream contactor or motor-protective device. The 160 A frame gives headroom for the 100 A trip — you're not running the frame at its thermal limit. ## What's in the Box The HQ designation means the auxiliary switches are rated for high electrical endurance — they'll handle the switching duty on a PLC input or a remote indication lamp without early failure. The trip alarm switch changes state only when the breaker trips on fault, not on manual open, so you can wire it to a horn or a SCADA alarm point.","metaTitle":"Siemens 3VA1110-5MH32-0AH0 Circuit Breaker, 55kA @ 415V, 100","metaDescription":"Siemens 3VA1110-5MH32-0AH0 IEC frame 160 MCCB, 55kA breaking capacity @ 415V, 100A TM120M starter protection.
