Product details

Line protection MCCB, 2-pole, 20 A

It is a 2-pole unit rated 20 A at 40 °C with a TM210 thermal-magnetic overcurrent release — meaning the thermal trip is fixed at 20 A and the magnetic short-circuit pickup is 10× the rated current (200 A).

The 3VM1120-3ED22-0AA0 measures 70 mm deep, 50.8 mm wide, and 130 mm tall. That 2-inch width means it occupies a single 2-pole space in a standard Siemens panelboard or MCC bucket. Depth of 70 mm (2.76 in) leaves clearance for wiring gutters in most 8-inch-deep enclosures.

The breaker holds 20 A continuously from 40 °C through 55 °C ambient. Maximum power loss is 8 W per pole.
