Product details

The Siemens SENTRON 3VA1110-3EF32-0CA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current (Iu) at 40 °C, with a TM240 thermal-magnetic release for line protection. Breaking capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V — enough to handle high-fault industrial feeders without cascading upstream. An integrated undervoltage release (UVR) is built in — no separate aux contact needed for that function. The TM240 release is fixed-thermal, fixed-magnetic; no field-adjustable trip settings, so the BOM spec is the trip spec.

IP40 on the front face; suitable for dry indoor panels, not washdown zones.

The 100 A rating holds through 50 °C ambient. Above that, derate linearly: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, 90 A at 70 °C.

Frequently asked questions

What is the breaking capacity of this MCCB at different voltages?

Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V.

What does the TM240 release mean on this breaker?

The TM240 is a fixed thermal-magnetic release — thermal element for overload, magnetic for short-circuit. No field adjustment; the trip curve is set at the factory.
