For a 100 A frame, that is a high interrupting rating, typical of a 'M' (medium) class in the 3VA1 family. The TM120M trip unit provides thermal-magnetic protection: the thermal element handles overloads (though this variant ships without overload protection — the TM120M is configured for short-circuit only), and the magnetic element handles instantaneous short-circuit trips. The adjustable Ii range (5–15 x In) lets you coordinate with downstream devices; set it low for sensitive loads or high for motor inrush. This breaker mounts in a standard IEC frame 160 footprint — panel builders will find it fits the same DIN-rail or screw-mount pattern as other 3VA1 units. The undervoltage release (UVR) operates on 120–127 V AC, 50/60 Hz; it trips the breaker when control voltage drops below about 70% of rated, which is standard for safety circuits that need to drop power on loss of control supply. Two auxiliary switches (HQ type) provide status feedback — one for the main contacts, one for the UVR or alarm state.","metaTitle":"Siemens 3VA1110-5MH32-0CC0 Circuit Breaker, 55kA @ 415V, 100","metaDescription":"Siemens 3VA1110-5MH32-0CC0 IEC frame 160 circuit breaker, 55kA breaking capacity at 415V, 100A TM120M starter protection.
