摘要： A combined trip actuator and accessory module for molded case circuit breakers is accessible in the field for user selected accessory options. The trip actuator includes a U-shaped stator with a permanent magnet at the end of one leg. A spring-loaded armature member extends across both legs to form a closed-loop magnetic circuit. The over-current trip coil and shunt trip coil are arranged on one leg with the undervoltage coil arranged on the other leg. The accessory module is accessible from the top surface of the breaker cover for field installation of the undervoltage and shunt trip coils to provide the corresponding undervoltage and shunt trip functions.

摘要： An electronic trip unit within a self-contained circuit interrupter utilizes dual electromagnetic trip actuators. One such actuator responds to overcurrent conditions to interrupt the protected circuit up to a predetermined value. The other such actuator interrupts the protected circuit at all overcurrent conditions in excess of the predetermined value.

摘要： A compact circuit breaker containing an electronic trip unit for interrupting overcurrent conditions within a protected circuit is made operable over a wide operating current range by means of current transformers having multiple turn primary windings. The primary windings are selected to provide a constant ampere-turns ratio to the current transformers without changing the size of the secondary winding or the volume of the transformer core.

摘要： 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 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 interface components.
