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. The 70 mm depth and 76.2 mm width fit a standard DIN-rail enclosure; IP40 on the front handles panel-side dust ingress, though the sides and back are open to the cabinet environment.
Breaking capacity and coordination
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. At 415 V the 121 kA rating still covers most industrial service-entrance faults; the drop to 17 kA at 500 V means it is not a universal high-fault device at higher voltages. The TM120M release is fixed-trip, so no field adjustment of the magnetic pickup — specify the exact load current when ordering.
Mounting and integration
Three-pole footprint: 76.2 mm wide, 130 mm tall, 70 mm deep. 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. Power loss is 9 W maximum — negligible for enclosure thermal budget but worth noting if the panel is densely packed.
