Product details

Breaking capacity is the headline number here: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 500/690 V. That is a high-interrupting rating for a 20 A frame — it sits comfortably ahead of most panelboard MCCBs in the same current class, which means it can be used as a main or branch device where fault current is substantial. For a line-protection role (cable/feeder protection) that is usually fine; you set the application at 20 A and leave it.

The 3VA1120-4ED32-0AA0 measures 130 mm high, 76.2 mm wide, 70 mm deep.

Frequently asked questions

What type of overcurrent release does it use?

A TM210 thermal-magnetic release — fixed, non-interchangeable. It provides both thermal (overload) and magnetic (short-circuit) protection without electronic adjustments.
