Description

The NBN150A is a single-pole, 50A MCB with a B-type tripping curve and dual breaking capacity of 10kA/15kA. The dual rating means it provides 10kA breaking capacity under standard conditions and up to 15kA under certain installation configurations, making it suitable for commercial and industrial sub-main circuit protection.
The B-type tripping characteristic is appropriate for resistive and lightly inductive loads where high inrush currents are not expected. The 1-module DIN rail format ensures space efficiency even at the 50A rating. Conductors up to 35mm² can be connected.
RoHS compliant and part of Hager’s NBN single-pole high breaking capacity MCB range, the NBN150A is compatible with standard MCB auxiliary accessories and suitable for distribution boards conforming to EN 60898-1.
