Air circuit breaker coil adapter

摘要

Air circuit breaker coil adapter for adapting an air circuit breaker, comprises: a coil unit housing for releasably receiving an air circuit breaker coil unit, the coil unit housing having a coil retainer element for preventing or limiting upward movement of an air circuit breaker coil unit therein; a locator at a bottom end of the coil unit housing for positively locating the coil unit housing in a plunger aperture of an air circuit breaker housing, the locator having a plunger aperture therethrough by which an interior of the coil unit housing is in-use communicable with an interior of the air circuit breaker housing; and a housing retainer element for at least in part preventing or limiting vertical displacement of the coil unit housing. An air circuit breaker using such an adapter and a method of adapting an air circuit breaker are also provided.

1. An air circuit breaker coil adapter for adapting an air circuit breaker, the coil adapter comprising a coil unit housing which releasably receives an air circuit breaker coil unit, the coil unit housing having a coil retainer element which prevents or limits upward movement of an air circuit breaker coil unit therein, a locator at a bottom end of the housing which positively locates the housing in an aperture of an air circuit breaker housing, the locator having a plunger aperture therethrough by which an interior of the coil unit housing is in use communicable with an interior of the air circuit breaker housing, and a housing retainer element which at least in part prevents or limits vertical displacement of the coil unit housing when mounted on the air circuit breaker housing; wherein the locator is a circular boss; and further comprising an outwardly projecting arm at or adjacent to the base of the coil unit housing, the arm including a location element thereon, being a downwardly projecting peg;
Wherein the coil unit housing has an upright back and a laterally extending base whereby the coil unit housing forms or substantially forms an L-shape, an upstanding front lip at a distal front edge of the base and which is spaced from and parallel or substantially parallel with the back.
