An integrated protection unit is a circuit breaker which includes basic overcurrent protection facility along with selective electrical accessories. A molded plastic accessory access cover secured to the integrated protection unit cover protects the accessory components contained within the integrated protection unit cover from the environment. A combined overcurrent trip actuator and multiple accessory unit is either field-installed or factory-installed within the integrated protection unit. One such actuator-accessory unit includes a fast release overcurrent trip circuit.
