Abstract

1,151,572. Contacts; heavy current switches. LA TELEMECANIQUE ELECTRIQUE. 25 July, 1966 [3 Aug., 1965], No. 33286/66. Addition to 1,104,674. Heading H1N. The bridging contact 6 of a circuit breaker is provided with slots as described in the main Specification. The fixed contact members are bent, at the point where their slots 25 are widest, to U-shape with one arm of the U carrying the contact elements 27, 27a while the other is bolted to the terminals of the switch. In the circuit breaker (Fig. 1, not shown) the bridge 6 is carried by an insulating assembly (3) operated by an electromagnet (1). The assembly (3) has a portion which extends through the gap between the fixed contacts to form an arc barrier between them.
