ACTUATOR-ACCESSORY RESET ARRANGEMENT FOR MOLDED CASE CIRCUIT INTERRUPTER OR ELECTRIC SWITCH

摘要

An integrated protection unit is a circuit breaker which in- cludes basic overcurrent protection facility along with selec- tive electrical accessories. A molded plastic accessory access cover secured to the integrated protection unit cover protects the accessory components contained within the integrated protec- tion unit cover from the environment. A combined overcurrent trip actuator and multiple accessory unit can be field-installed within the integrated protection unit. The combined actuator-accessory unit includes electronic control circuitry for the accessories along with mechanical trip and reset inter- face components. The reset mechanism allows the actuator-accessory unit to become reset without interfering with the operation of the integrated protection unit.
