Breaking capacity and thermal rating
The 3VA1110-3ED26-0AA0 is a 2-pole SENTRON molded case circuit breaker rated 100 A at 40 °C, with a TM210 thermal-magnetic overcurrent release designed for line protection. Its interrupting capacity reaches 75.6 kA at 240 V AC and 52.5 kA at 415 V AC — figures that determine whether this breaker coordinates with downstream devices in a selective scheme or needs a current-limiting upstream breaker to stay within its SCCR.
Derating and ambient limits
The insulation voltage is rated 500 V, and the operating voltage is 415 V AC or 250 V DC.
Panel fit and protection class
Dimensions are 70 mm deep, 50.8 mm wide, and 130 mm high — a 2-inch-wide footprint that fits standard 2-pole MCCB panel slots. Maximum power loss is 16.66 W, which factors into enclosure thermal calculations when grouping multiple breakers.
