Patent attributes
An improved filter assembly for a circuit breaker includes a generally rectilinear filter housing having at least two filter mounting zones for receiving at least two filter assemblies, so as to define, in the aggregate, a filter assembly, and at least two filter assemblies configured for interfitting with the filter mounting zones of the filter housing, each filter assembly comprising a generally rectilinear filter body having a given peripheral configuration and a filter gasket configured for interfitting about a periphery of the filter body for sealingly engaging the filter body relative to the filter housing in response to forces encountered by the filter assembly both upon assembly and in operation. The filter assembly may further have a small hole diffuser having a peripheral configuration similar to the peripheral configuration of the filter bodies, in the aggregate, when assembled with the filter housing and configured for interfitting within the filter housing.
