摘要： A molded case multi-pole circuit breaker having an electronic trip unit to determine overcurrent conditions connects with a corresponding current transformer within each pole to sample circuit current. Upon the occurrence of an overcurrent condition, a trip actuator is energized to interrupt the circuit current. A current transformer adapter unit supports the trip actuator wire conductors and pin connectors while at the same time shielding the current transformers from the circuit breaker exhaust gases.

摘要： A molded case circuit breaker movable contact arm electrically connects with the circuit breaker load terminal by means of parallel electric paths provided by a looped braid conductor. The contact arm support includes a single support leg for pivotally retaining the movable contact arm on one side. The opposite side of the contact arm is supported on the operating mechanism crossbar. Contact arms of increasing thickness are used to accommodate the higher transport currents required with circuit breakers of increased ampere ratings.

摘要： A blocking apparatus for blocking a contact structure from closing in a circuit breaker is provided. The apparatus includes a link extending from the circuit breaker and connected to a movable contact arm. The contact structure, being operated by an operating mechanism, remains in a separated position even when the operating mechanism is in the “ON” position due to the connection with the link of the blocking apparatus. A release assembly releases the link when it is desired to close the movable contact arm.

摘要： A combined bell alarm and lock-out accessory is connected with the electronic trip unit that controls a high ampere rated circuit breaker. The accessory interacts with the circuit breaker operating mechanism to activate the bell alarm upon circuit interruption and to prevent the closing of the circuit breaker contacts until the accessory is manually reset. The circuit breaker lock-out mechanism interfaces between the circuit breaker operating mechanism and the accessory to insure that the contacts remain open until the accessory is completely reset.

摘要： This invention relates to a high ampere-rated circuit breaker which meets the electrical code requirements of the world market. The charging of the powerful operating springs controlling the circuit breaker contacts is made manually by means of an operating handle and a ratchet and pawl assembly. A two-stage latching arrangement controls the retention and release of the pawl to retain and discharge the operating springs. The operating springs cannot become discharged until and unless the operating handle is in a fully retracted position.
