摘要： A compression spring is disclosed, which is configured to be used for various applications, and in particular for operate accessory linkages. Furthermore, a compression spring retention system is disclosed including a compression spring and a housing in which the compression spring is fixable. The compression spring includes a length of coiled wire having substantially a circular cross-sectional area, wherein at least a first end of the compression spring is formed as a retainer device that is configured to be compressed while being mounted into a recessed chamber of the housing and to expand when inserted into the recessed chamber in a way that the compression spring is fixed at the recessed chamber.

摘要： A circuit breaker having a housing with an accessory cover includes an accessory cover interlock assembly that trips the circuit breaker upon removal of the accessory cover. The accessory cover interlock assembly includes a plunger rotatable from an initial install position to an engaged position that moves a trip lever into a de-energize position (tripping the circuit breaker) upon removal of the accessory cover. The accessory cover interlock assembly prevents the circuit breaker from being reset while the access cover is removed. The accessory cover interlock assembly automatically resets upon re-attachment of the accessory cover to the circuit breaker housing. Methods of forced safety tripping in a circuit breaker are also provided, as are other aspects.
