The Siemens 3VA1110-5MH32-0AF0 is a 3-pole molded-case circuit breaker in the 3VA1 IEC frame 160 series, rated at 100 A with a breaking capacity of 55 kA at 415 V (class M). It is configured for starter protection — the TM120M thermal-magnetic release provides short-circuit protection adjustable from 5 to 15 times In, but there is no overload protection element in this variant, so it relies on an upstream or separate overload relay for motor branch-circuit protection. The package includes a nut keeper kit, one auxiliary switch (HQ), and one trip alarm switch (HQ).
Where it fits
Mounts on a DIN rail or panel-mount base inside a motor control center or distribution board. The 55 kA interrupting rating at 415 V makes it suitable for high-fault-capacity industrial feeders — think pump skids, conveyor drives, or compressor branch circuits where the available fault current exceeds 25 kA. The auxiliary and alarm switches feed status back to a PLC or SCADA system without needing an external interface relay.
