The SENTRON 3VA1110-5ED32-0KH0 is a 3-pole molded case circuit breaker (MCCB) rated 100 A at 40 °C, with a breaking capacity of 121 kA at 415 V. It's designed for line protection — the kind of workhorse that sits in a main distribution panel or a motor control center, protecting feeders and branch circuits from short circuits and overloads. The 100 A continuous rating holds flat from 40 °C up to 50 °C, then derates gradually to 91 A at 70 °C, so you don't lose headroom in a warm enclosure.
Breaking capacity and what it means for your line
At 415 V, this MCCB interrupts 121 kA symmetrical. At 240 V it's even higher at 187 kA.
Width is a standard 3-inch footprint for a 3-pole frame, so it drops into existing SENTRON 3VA mounting bases or panel cutouts without re-drilling.
Auxiliary and trip options
It does not have an undervoltage release, so if you need undervoltage protection, you'd look at a different suffix. The trip indicator is present, so you get a visual flag when the breaker trips on fault.
