ABSTRACT:
A conversion kit in the form of a flux shifter unit that interfaces with the circuit breaker operating mechanism and is installable without dismantling the circuit breaker is proposed herein. The flux shifter unit responds to the electronic trip unit to articulate the circuit breaker operating mechanism and separate the circuit breaker contacts upon occurrence of an overcurrent condition. Tolerance take-up for various manufacture's designs is achieved by expansion springs while electrical interface with remote accessories and other electronic trip units is achieved by button-actuated switches.
