ABSTRACT:
A single-sized circuit breaker electric isolation block provides both electric insulation between the circuit breaker operating mechanism as well as mechanical support to the circuit breaker contact arm assembly over a wide range of circuit breaker ampere ratings. The isolation block is formed from a plastic composition and is shaped to receive the circuit breaker operating mechanism connector link for each phase of a multi-phase circuit breaker assembly. The positional relationship on the block accommodates the connector links used with a wide range of circuit breaker ampere ratings.
