The Siemens SENTRON 3VM1110-4ED22-0AA0 is a 2-pole molded case circuit breaker (MCCB) rated 100 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release. The 70 mm depth and 50.8 mm width fit standard DIN-rail or panel-mount cutouts common in industrial switchboards.
This matters for enclosures with multiple heat sources — if the panel ambient runs 55 °C, the breaker is good for 98 A.
The 2-pole form factor occupies a 50.8 mm wide slot — standard for 2-pole MCCBs in North American and European panel schedules.
