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. It delivers 121 kA interrupting capacity at 240 V AC and 76 kA at 415 V AC — the high fault-current rating means it can be used as a main breaker in panels fed by large transformers or utility services, not just as a feeder downstream. The 70 mm depth and 50.8 mm width fit standard DIN-rail or panel-mount cutouts common in industrial switchboards.
Thermal derating and ambient limits
The 100 A rating holds up to 50 °C; above that it derates linearly to 91 A at 70 °C. This matters for enclosures with multiple heat sources — if the panel ambient runs 55 °C, the breaker is good for 98 A. The maximum operating ambient is 70 °C, with storage range from -40 °C to 80 °C.
Panel integration and wiring
The 70 mm depth leaves clearance for rear-connected busbars in a typical 200 mm deep enclosure. The 2-pole form factor occupies a 50.8 mm wide slot — standard for 2-pole MCCBs in North American and European panel schedules. No undervoltage release, no shunt trip, and no communication module are built in; these are optional add-ons if needed.
