The Siemens 3VA1220-5EF42-0KC0 is a SENTRON molded case circuit breaker (MCCB) rated at 200 A continuous current across the 40 °C to 50 °C band — it holds full rating up to 50 °C, then derates to 176 A at 70 °C. Interrupting capacity runs 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V — so it handles high-fault utility feeds and large motor branch circuits without cascading upstream.

Frequently asked questions
Where can I buy 3VA1220-5EF42-0KC0 and what is the lead time?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or lead-time number is published here.
What is the interrupting capacity of this MCCB at different voltages?
187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. These ratings govern selectivity and SCCR coordination in the distribution panel.
Does 3VA1220-5EF42-0KC0 include a shunt trip release?
Yes, it ships with a shunt trip (STL) release and two auxiliary switches HQ built in — no separate order needed for remote tripping capability.
