What this MCCB carries
The SENTRON 3VM1110-5ED32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a TM210 thermal-magnetic overcurrent release. It's rated 100 A continuous at 40 °C — no derating needed until you push past 55 °C, where it drops to 98 A, then 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. That means in a warm panel you still get nearly full rated current; only above 55 °C do you start losing headroom. Interrupting capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V, 76 kA at 440 V, and 17 kA at 500 V. That's a lot of fault-clearing muscle — it'll handle high available fault currents downstream of a large transformer without a cascading failure upstream.
Panel fit and mounting
Dimensions are 130 mm tall, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint. It mounts on a DIN rail or directly to a backplate. The front face carries IP40 protection, so it's fine inside a closed enclosure; keep it out of washdown zones. No undervoltage release, no shunt trip, no ground-fault monitoring, no communication module — this is a basic thermal-magnetic breaker for straightforward line protection. If you need aux contacts or remote trip, you'll add them externally.
