Interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V, and still 187 kA at 500 V; at 690 V it drops to 3.7 kA — that last number tells you this breaker is sized for 400 V class distribution, not 690 V motor feeders. Three poles, 300 A minimum to 1 500 A maximum frame rating — the 100 A thermal-magnetic trip is set at the factory. Undervoltage release (UVR) is built in, so if your control voltage drops, the breaker opens without a separate shunt trip module.

Product details
Frequently asked questions
What is the interrupting capacity of 3VA2110-7MS36-0BL0 at 240 V?
330 kA at 240 V. At 415 V and 440 V it's 242 kA; at 500 V it's 187 kA; at 690 V it drops to 3.7 kA. That 690 V number is the weak point — this breaker is designed for 400 V class distribution, not 690 V motor feeders.
What is the continuous current rating and does it derate with temperature?
100 A continuous from 40 °C all the way up to 70 °C — no derating needed across that entire operating range. That's unusual for an MCCB; most start losing capacity above 40 °C.
Where can I buy 3VA2110-7MS36-0BL0 and how is it quoted?
Sourced and quoted to order through independent industrial distribution. Submit an RFQ for current pricing and availability — confirmed at quote time, not before.
