Product details

The Siemens SENTRON 3VA1020-3ED36-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated 20 A continuously at 40 °C, with a 75.6 kA interrupting capacity at 240 V — enough to handle most distribution panel fault currents without cascading upstream. It is a line-protection device, meaning it is sized for feeder or branch circuits rather than motor-starting duty.

Interrupting capacity drops as voltage rises: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V.

The breaker holds 20 A from 40 °C up to 55 °C, then derates to 19 A at 60 °C through 70 °C. Maximum power loss is 12 W.

Integrated accessories

Insulation voltage rated 800 V.

Frequently asked questions

What is the closest functional second-source for 3VA1020-3ED36-0KC0?

The 3VA1020-3ED36-0AA0 is a near-identical variant — same frame, same 20 A rating, same 3-pole configuration — but it lacks the shunt trip and auxiliary switches that the -0KC0 carries. If your BOM needs the remote trip and status contacts, the -0KC0 is the correct fit.

Where can I buy 3VA1020-3ED36-0KC0 and how is it quoted?

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