Abstract

A circuit breaker (1) comprises a base (20) and cover (21) with rear, front and side wall portions which cooperate on assembly of the base (20) and cover (21) to form an enclosure for the various components of the circuit breaker. An enclosed arc chamber (50) into which arc gases generated on tripping of the breaker under load are exhausted is defined by a longitudinal dividing wall (51), portion of the rear wall (22a, 22b) and a transverse dividing wall (53). The arc gases enter the chamber (50) through an aperture (52) and are prevented from exiting the breaker. This eliminates cross-phasing in the load centre in which the circuit breaker is mounted.
