ABSTRACT:
A secondary arc chute is for an electrical switching apparatus including a housing, a pair of separable contacts enclosed within the housing, and a primary arc chute disposed proximate the separable contacts in order to attract an arc generated by the separable contacts. The primary arc chute has a first end including an arc horn, and a second end. The secondary arc chute includes a chute member made from a magnetic material, such as nickel-plated steel, and including a first portion disposed at or about the arc horn of the primary arc chute, and a second portion. The chute member provides an extension of the primary arc chute in order to facilitate drawing the arc away from the separable contacts and to ground the arc into the housing of the electrical switching apparatus.
