Embodiment Construction

[0022] From figure 1 It can be seen that the circuit disconnector 1 comprises an insulating housing 3 mainly formed by two half-shells, the upper half-shell of which has been removed in order to be able to see the interior of said circuit disconnector. The housing 3 has a substantially parallelepiped shape corresponding to the modular system. The housing 3 has a rear side panel 5 and a front side panel 7 , the rear side panel 5 is used to be fixed on the guide rail, and the front side panel 7 has a hole through which the operating handle 9 passes. The circuit breaker 1 comprises a neutral breaking circuit and a phase breaking circuit respectively arranged on each side of an insulating separator 11 interposed between the two half-shells and extending parallel to the main panel of the housing 3 . exist figure 1 In , only the phase breaking circuit can be seen, while the neutral breaking circuit is located behind the insulating divider 11 .

Abstract

The invention relates to a switching device, comprising an insulating shell for containing a movable contact. The movable contact is supported by first ends of at least two contact arms surrounding a pivot pin (21) respectively so that the contact arm rotates to the closed position of the contact. The device comprises a contact pressure-applying tool. The contact pressure-applying tool comprises two torsion springs (31, 32) independently acting on the contact arms. Corresponding to the acted contact arm, each torsion spring is configured so that the rotary axis of a spring deviates to the second end of the contact arm corresponding to the axis of the pivot pin.

Description

technical field [0001] The invention relates to the field of switching devices of the circuit breaker or differential circuit breaker type, in particular single-pole plus neutral circuit breakers. Such circuit breakers are commonly used in terminal distribution facilities, especially buildings, to protect the circuit by interrupting both the phase and neutral conductors. [0002] In particular, the invention relates to a switchgear having an insulating housing accommodating a movable contact comprising at least one phase movable contact and a neutral one respectively supported by first ends of at least two contact arms Movable contacts, each contact arm mounted about a pivot pin to allow rotation of said contact arm to a closed position of said contact, said means comprising a contact pressure applied to said contact arm contact pressure tool. Background technique [0003] Patent application EP0042778 describes a single pole plus neutral circuit breaker comprising two mova...
