Abstract
A molded case circuit breaker includes accessory functions such as an auxiliary switch and a shunt trip device mounted within the circuit breaker cover. A stain relief assembly interfaces the accessory wires with the circuit breaker case and cover. The strain relief fixture prevents inadvertent or intentional displacement of the wires from the accessory devices.
