Product details

Siemens SENTRON 3VA1110-6EF32-0CA0 — 100 A MCCB with Undervoltage Release

The Siemens SENTRON 3VA1110-6EF32-0CA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 100 A continuously at 40 °C and derating to 91 A at 70 °C. The TM240 thermal-magnetic overcurrent release handles the overload and short-circuit trip curve.

Breaking Capacity by Voltage Level

Rated breaking capacity is voltage-dependent: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V.

Above that, derate to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Maximum power loss is 27.5 W — relevant for panel heat calculations when grouping multiple breakers in a closed enclosure.

Frequently asked questions

What is the breaking capacity of 3VA1110-6EF32-0CA0 at 415 V?

154 kA at 415 V. The breaker also carries 220 kA at 240 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V.

What does the undervoltage release do on this MCCB?

The undervoltage release (UVR) trips the breaker when the control voltage drops below a threshold, used in safety circuits or emergency-stop chains where loss of control power must open the main feeder.

Where can I buy 3VA1110-6EF32-0CA0?
