ABSTRACT:
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 circuit breaker cover from the environment. An auxiliary switch unit is one such accessory component which can be field-installed without affecting the integrity of the circuit breaker and which is connected to a remote indicator connected by external wire conductors to signal the "ON" or "OFF" condition of the circuit breaker contacts. The auxiliary switch unit enclosure is specially shaped to protect the auxiliary switch from damage due to excess tension on the external wire conductors.
