Abstract
A switchgear unit contains interlocked circuit breaker and fuse compartments. The interlock prevents the fuses from being withdrawn from their power stabs until the circuit breaker is withdrawn from its power stabs first. A mechanical linkage arrangement causes an interference between the racking tool and the fuse compartment racking shaft until the breaker is withdrawn from the breaker compartment power stabs.
