Siemens 3VA1132-6EE36-0AA0 SENTRON MCCB, 3-Pole, 32 A, 220 k

The TM220 thermal-magnetic release handles overload and short-circuit without an external trip unit.

The 76.2 mm width (3 in) and 70 mm depth (2.76 in) fit standard 3-pole MCCB slots in most North American and European enclosures.

Rated insulation voltage 800 V, so it handles 480/600 V systems with headroom. The interrupting curve drops from 220 kA at 240 V to 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500/690 V — that's still a solid number for most industrial services. Power loss max 10.6 W.
