ABSTRACT:
A high performance, manually and automatically operable, trip-free magnetic circuit breaker incorporates novel means for mounting and coupling circuit breaker units to achieve multipole operation. An actuator in each pole has a shaft extending through a housing wall and fitting in splined engagement with the shaft of a corresponding actuator in an adjacent pole mounting the actuators for unison pivotal movement between a position where one of the actuators is engaged and pivoted by movement of the beaker contacts to an open circuit position in one pole for pivoting the other actuator to trip the breaker components in the adjacent pole to open the circuit in the adjacent pole. A tie-pin having a peripheral groove therein is snugly fitted into openings in the operating handles of the breaker pols and has coil springs fitted over the pin between pairs of the handles, one spring having a convolution of reduced diameter fitted into the pin groove for retaining the pin in the handle openings.
