What this MCCB carries and where it fits
The Siemens SENTRON 3VM1132-3ED32-0AA0 is a 3-pole molded case circuit breaker rated 32 A at 40 °C, with a TM210 thermal-magnetic release tuned for line protection. It breaks 76 kA at 240 V AC and still holds 53 kA at 415 V — numbers that tell you it handles high-fault service entrances and distribution feeders without a sweat. The 70 mm depth and 76.2 mm width keep it on a standard DIN-rail or panel-mount footprint; you won't be re-drilling a gland plate to swap one in.
Ratings that matter on the route
The interrupting capacity drops from 76 kA at 240 V to 12 kA at 500 V — that's the arc-extinction physics of a 3-pole MCCB. If your panel feeds a 480 V motor control center, the 12 kA at 500 V is the number that governs your fault-current study, not the 240 V figure. The thermal derating is flat from 40 °C to 50 °C at 32 A, then eases to 30 A at 70 °C. Out here in the grease, a breaker that holds its rating up to 50 °C means you can mount it near a warm drive cabinet without oversizing.
Panel integration and wiring
The 70 mm depth and 76.2 mm width fit standard 3-pole MCCB cutouts. IP40 on the front means it's protected against solid objects larger than 1 mm — fine for a clean indoor panel, but don't hose it down. Rated insulation voltage is 800 V, so it's comfortable in 480 V and 600 V class systems. The TM210 release is a fixed thermal-magnetic type; no interchangeable trip units, which simplifies spares stocking — one breaker, one trip curve, no calibration drift.
