Product details

The Siemens 3VM1020-3ED46-0AA2 is a 4-pole IEC molded-case circuit breaker in the 3VM1 frame, rated 20 A continuous (Ir fixed at 20 A) with a breaking capacity Icu of 25 kA at 415 V AC. The TM210 thermal-magnetic trip unit provides fixed overload protection (Ir = In) and a fixed short-circuit pickup at 16 × In (320 A); there is no dial to adjust, so the BOM line is locked once specified.

The FTFM (fixed thermal, fixed magnetic) trip means no field calibration is needed, so it is a straight swap for a failed unit on a live line.

Frequently asked questions

What is the breaking capacity of 3VM1020-3ED46-0AA2?

The breaking capacity Icu is 25 kA at 415 V AC, which is class N for the 3VM1 frame — sufficient for most industrial sub-distribution panels with high fault currents.

Where can I buy 3VM1020-3ED46-0AA2?

This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
