Description

The MU320A is a 3-pole, 20A MCB with a C-type tripping curve and 6kA breaking capacity, suitable for three-phase circuits supplying moderate loads with inrush current characteristics, such as small three-phase motors, HVAC equipment, or three-phase socket outlets.
The 3-module DIN rail format provides space-efficient three-phase disconnection in commercial distribution boards. Compatible with three-phase comb busbar systems for simplified supply connection.
RoHS compliant and part of Hager’s MU three-pole MCB range, the MU320A supports standard MCB auxiliary accessories and is suitable for three-phase circuit protection in commercial and industrial distribution boards.
