Product details

The Siemens SENTRON 3VA1220-6EF32-0KH0 is a 3-pole molded case circuit breaker rated for 200 A continuous at 40 °C, with a breaking capacity of 220 kA at 240 V AC — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream.

Above that it derates linearly: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. Breaking capacity also drops with voltage: 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V.

The auxiliary switch design (2 aux + 1 trip alarm HQ) and the shunt trip release are factory-installed, not field-add-on kits. Verify the wiring diagram matches your control voltage before panel assembly — the shunt trip coil draw is not listed here, but typical STL coils pull about 0.5 A at 24 VDC during the trip pulse.

Frequently asked questions

Where can I buy 3VA1220-6EF32-0KH0 and how is it quoted?

This part is sourced to order through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time, not listed here.

What is the breaking capacity of this MCCB at 240 V?

220 kA at 240 V AC — suitable for high-fault utility feeds or transformer secondaries without cascading upstream breakers.

Does this breaker include a shunt trip and auxiliary switches?

Yes, it comes with a factory-installed shunt trip (STL) release and a 2-auxiliary-switch + 1-trip-alarm-switch HQ pack — no field-add-on kits needed.
