The SENTRON 3VM1163-5MH32-0AA0 is a 3-pole molded case circuit breaker (MCCB) with a TM120M thermal-magnetic overcurrent release, rated 63 A at 40 °C and derated to 58 A at 70 °C. Its breaking capacity reaches 187 kA at 240 V AC, stepping down to 121 kA at 415 V and 17 kA at 500 V — figures that define the selectivity headroom for a downstream panel. IP40 on the front handles panel-side dust ingress, though the sides and back are open to the cabinet environment.
At 240 V this MCCB clears 187 kA — the highest rating in the evidence set — which gives the upstream transformer or main breaker room to coordinate without a series-rated compromise. The TM120M release is fixed-trip, so no field adjustment of the magnetic pickup — specify the exact load current when ordering.
Mounts on DIN rail or direct-panel via the screw terminals. The IP40 front allows a cutout in the gland plate for the operating handle; no auxiliary contacts, undervoltage release, or communication module are built in (all flagged as No in the evidence), so any add-on accessories must be wired externally.
