Product details

The Siemens SENTRON 3VA1220-6MH32-0KH0 is a 3-pole molded case circuit breaker rated 200 A continuous, designed for starter protection in motor control centers and distribution panels. Its interrupting capacity hits 220 kA at 240 V and still delivers 154 kA at 415 V — enough to clear high-fault scenarios on large motor feeders without cascading upstream.

Breaking capacity across voltage levels

At 240 V the breaker clears 220 kA; at 415 V it holds 154 kA, at 440 V it drops to 75.6 kA, at 500 V to 30 kA, and at 690 V to 4.5 kA. That steep derating is typical for a compact MCCB — the arc extinction physics scale with voltage. For a 480 V feeder (common in North American mills) the 30 kA at 500 V is the relevant figure; confirm your available fault current stays under that.

Auxiliary and release options

Comes factory-fitted with two auxiliary switches plus one trip alarm switch (HQ), and a shunt trip release (STL) for remote tripping. The shunt trip lets a safety PLC or E-stop circuit drop the breaker independently of the overload curve — useful for emergency-off chains. No undervoltage release fitted, no ground-fault monitoring module.

Frequently asked questions

Where can I buy 3VA1220-6MH32-0KH0 and how do I get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.

What is the closest functional second-source to 3VA1220-6MH32-0KH0?

The 3VA1110-5EF32-0AM0 is a smaller-frame sibling (100 A class) — same SENTRON platform, same auxiliary-switch architecture, but lower continuous rating and interrupting capacity. It will not drop in without re-calculating the feeder's fault current and load.

What compliance documentation does Siemens provide for 3VA1220-6MH32-0KH0?

Standard Siemens SENTRON MCCBs carry UL 489, CSA C22.2 No. 5, and IEC 60947-2 certifications, plus RoHS and REACH declarations. Specific declaration numbers are available on request.
