Claims

[Scope of utility model registration request]

(1) Multi-pole fixed contacts arranged in parallel in an insulating case,
a movable contact support made of an insulating material and having a movable contact that faces each of the fixed contacts so as to be able to approach and separate;
In the contact device equipped with a separating element for a movable contact inserted between each movable contact of the movable contact support and between fixed contact poles of the front insulating case, the A circuit interrupter characterized in that the spring is provided with an arc-resistant insulating cover that has elasticity that allows the spring to be deformed as the movable contact moves toward and away from the contact, and that shields at least the contact between the electrodes. device contactor device.

(2) Utility model registration Claim 1: The contact device for a circuit breaker, wherein the cover is a cylindrical insulating tube arranged parallel to each contact. .
