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 arc gas controller-insert is used with molded case circuit breaker covers to direct the flow of arc gases that occur during intense overcurrent circuit interruption. The gas controller-insert provides access to the line and load terminal lugs for connection with and disconnection from an associated electrical power distribution system while controlling the egress of the arc gases.

摘要: A combined arc gas controller-line terminal plug is used within molded case circuit breaker covers to direct the flow of arc gases that occur during intense overcurrent circuit interruption. The plugs simultaneously prevent access to the line terminal lugs while controlling the egress of the arc gases. Moreover, the plugs are removable for connection with and disconnection from an associated electrical power distribution system.

摘要: A compact circuit breaker utilizing an electronic trip unit for overcurrent determination contains a compact slot motor and a compact arc chute to minimize and control the arc that occurs when the circuit breaker fixed and movable contacts become separated upon intense overcurrent conditions. The fixed contact is arranged on a fixed contact arm that includes an arc runner for rapidly directing the arc into the arc chute. The arc chute includes a keying arrangement which cooperates with slots formed within the circuit breaker case interior sidewalls to orient the arc plates relative to the arc runner.
