What the ratings mean for fit
The Siemens SENTRON 3VM1110-3ED22-0AA0 is a 2-pole molded case circuit breaker rated 100 A continuous at 40 °C, with a TM210 thermal-magnetic release providing LI (long-time and instantaneous) protection. The 100 A rating holds through 50 °C; above that it derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C — so for a 100 A load in a warm enclosure (say 55 °C internal ambient), you need to step up one frame size or accept the 98 A limit. Breaking capacity is 76 kA at 240 V AC and 53 kA at 415 V AC — that's the fault current it can safely interrupt without welding contacts or rupturing the case. For a 415 V distribution panel with a prospective short-circuit current of, say, 50 kA, this breaker has 3 kA of headroom. The rated insulation voltage is 500 V, and the maximum DC operating voltage is 250 V, so it's suited for 2-wire DC circuits up to that level.
Panel integration and compliance
The 3VM1110-3ED22-0AA0 mounts on a DIN rail or panel base — the 70 mm depth, 50.8 mm width, and 130 mm height fit standard SENTRON 2-pole MCCB footprints. Front IP40 protection means it's suitable for enclosed distribution boards where no water ingress is expected. No undervoltage release, no shunt trip, no communication module — it's a plain thermal-magnetic breaker for line protection. Compliance documentation (CE, IEC 60947-2) is standard with the SENTRON series; the manufacturer provides RoHS and REACH declarations on request.
