Embodiment Construction

[0021] figure 1 A circuit breaker 1 incorporating the invention is shown. The circuit breaker 1 has a housing 3 formed by a base 5 , a first cover 7 cooperating with the base 5 and a second cover 9 mounted on the first cover. The circuit breaker 1 in this example has three poles 11A, 11B and 11C, but the invention can be applied to a circuit breaker with two or more poles. exist figure 1 The load conductors 13A, 13B and 13C for these electrodes can be seen in . The handle 15 is used to manually close and open the circuit breaker 1 .

[0022] figure 2 and 3 Only the relevant internal components of the circuit breaker 1 are shown. Each pole of circuit breaker 1 , for example pole 11A, has a separable contact 17 in the form of a fixed contact 19 and a movable contact 21 . The fixed contact 19 is mounted on a wire 23 , while the movable contact 21 is attached to the end 25 of a contact arm 27 . The frame 31 supports the contact arm 27 for pivotal movement about the axis 2...

Abstract

A U-shaped accessory actuator clip that snaps onto the crossbar of a multipole circuit breaker is integrally molded of a compliant material with a flexible finger that actuates / deactuates an accessory, such as an auxiliary switch, as the contacts of the breaker close and open.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application Serial No. 60 / 615,446, filed October 1, 2004. technical field [0003] The present invention relates to circuit breakers having auxiliary switches indicating the state of the contacts of the circuit breaker, and more particularly to means for actuating the auxiliary switches. Background technique [0004] Many circuit breakers are commonly provided with auxiliary switches that indicate the open or closed state of the circuit breaker contacts. Usually, an auxiliary switch is available as an option. For example, an auxiliary switch can be added, if desired, by inserting a compartment in the first cover of the circuit breaker closed by the second cover. The plunger of the auxiliary switch extends through an opening in the first cover where it is actuated by a protrusion molded into the crossbar that connects the movable contact arm of the multi-pol...
