Product details

Siemens SENTRON 3VA1220-6MH32-0JC0 — 200 A MCCB with shunt trip

It carries a 220 kA interrupting rating at 240 V AC, stepping down to 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V — so the available fault current at the panel dictates which voltage column governs your coordination study. The unit includes a factory-installed shunt trip (STL) and two HQ auxiliary switches, saving a panel-build step versus field-fitting them later.

Rated 200 A continuous at 40 °C through 50 °C ambient; above that the breaker derates linearly to 176 A at 70 °C. Maximum power loss is 42 W per pole — enough heat to factor into enclosure ventilation if you are stacking multiple breakers in a sealed cabinet.

The depth leaves clearance for rear-connected bus bars or a cable entry gland plate.

Frequently asked questions

What is the breaking capacity of 3VA1220-6MH32-0JC0 at 415 V?

154 kA at 415 V AC, which is the typical voltage for 400 V class three-phase industrial systems.

Does this MCCB include a shunt trip or auxiliary contacts?

Yes, it comes with a factory-installed shunt trip (STL) and two HQ auxiliary switches, so no separate ordering or field assembly is needed for those functions.

Where can I buy 3VA1220-6MH32-0JC0 and how is it quoted?

Sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.
