Abstract
An insulative body, affixed to a switchboard, mounts a pair of spring biased, reciprocating, conductive plungers individually wired to each side of a neutral current transformer secondary winding. With a drawout circuit breaker in its engaged position, the plungers retract in response to engagement with breaker mounted conductive pads wired to a breaker static trip unit, thereby completing a circuit between the secondary winding and the breaker trip unit. With the breaker in its disengaged position, the plungers spring to extended positions in disengaging relation with the pads, while plunger mounted switch contacts connect the winding sides together through a shorting bar or a resistor.
