Product details

The Siemens 3VA1020-4ED36-0BC0 is a 3-pole IEC circuit breaker on the 3VA1 frame, rated at In=20A with a TM210 thermal-magnetic trip unit providing fixed overload protection at Ir=20A and fixed short-circuit protection at Ii=16 x In.

Integration and deployment

The clamp connection accepts copper or aluminium conductors up to the frame's rated cross-section. The integrated undervoltage release (UVR) at 24V DC trips the breaker on loss of control voltage — common in emergency-stop chains or safety circuits where a sustained undervoltage must open the load.

Frequently asked questions

Where can I buy 3VA1020-4ED36-0BC0?

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

What is the breaking capacity of 3VA1020-4ED36-0BC0?

It has a breaking capacity class S with Icu=36kA at 415V AC, which determines its ability to safely interrupt high fault currents in IEC 60947-2 rated systems.
