ABSTRACT:
A threshold coupling device for releasing the mobile contacts of circuit breakers when short circuits appear. A rectangular section blade (13) with longitudinal faces (13', 13") associated with a contact holder (10) is provided with balls (29, 30) which cooperate with a resilient clip (33) for providing a threshold mechanical connection between the contact (6) and an operating member (1, 2) which carries this clip. This coupling is advantageously used in circuit-breaker limiters.
