Abrégé

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.

Abrégé

An air circuit breaker coil adapter (10) for adapting an air circuit breaker (50), comprises: a coil unit housing (12) for releasably receiving an air circuit breaker coil unit (48), the coil unit housing (12) having a coil retainer element (28) for preventing or limiting upward movement of an air circuit breaker coil unit (48) therein; a locator (14) at a bottom end of the coil unit housing (12) for positively locating the coil unit housing (12) in a plunger aperture of an air circuit breaker housing (54), the locator (14) having a plunger aperture (36) therethrough by which an interior of the coil unit housing (12) is in use communicable with an interior of the air circuit breaker housing (54); and a housing retainer element (16) for at least in part preventing or limiting vertical displacement of the coil unit housing (12) when mounted on the air circuit breaker housing (54). An air circuit breaker (50) using such an adapter (10) to mount one or more operating coil units (48), and a method of adapting an air circuit breaker (50) utilising a cylindrical or substantially cylindrical operating coil unit to a non-cylindrical operating coil unit (48) are also provided.
