A thermal detection system () contains a plural pole circuit breaker () and a resistance temperature detector adhesive tape () connected to an electric circuit () that detects the resistance change in the adhesive tape (), which in turn sends a signal to a shunt trip () connected to the circuit breaker ().

Bus bar thermal detection

An externally controllable circuit breaker includes a set of main contacts, an operating mechanism for opening and closing the main contacts; and a set of secondary contacts electrically connected in series with the main contacts. A control mechanism to open and close the secondary contacts includes an electromagnet with an armature having a first position, which opens the secondary contacts, and a second position, which closes the secondary contacts. The electromagnet also includes a coil electrically interconnected with the main contacts for energization therefrom and adapted for control by one or two external signals from one or two external contacts to operate the armature between the first and second positions.

Externally controllable circuit breaker

A circuit breaker includes a housing, separable contacts, an operating mechanism having a pivotally mounted operator handle for opening and closing the separable contacts, and a trip mechanism releasing the operating mechanism to move the operator handle to its tripped position. A micro-switch includes an actuator lever movable between an actuated position and a non-actuated position and adapted to engage a surface of the operator handle. The micro-switch also includes a normally open contact having a closed state corresponding to the actuated position and an open state corresponding to the non-actuated position. The operator handle surface engages and moves the actuator lever to the actuated position in only the ON position of the operator handle. The actuator lever is in the non-actuated position in the OFF position and the tripped position of the operator handle.

Circuit breaker

A circuit breaker includes a set of main separable contacts, an operating mechanism for operating the main separable contacts, a set of secondary separable contacts in series with the main separable contacts, and a solenoid mechanism for operating the secondary separable contacts. A first auxiliary switch is responsive to the operating mechanism, and a second auxiliary switch, electrically connected to the first auxiliary switch, is responsive to the solenoid mechanism. An input terminal for a control voltage is electrically connected to the first and second auxiliary switches. A first diode is electrically connected with a forward polarity between the first auxiliary switch and an output terminal. A second diode is electrically connected with a reverse polarity between the second auxiliary switch and the output terminal.

Circuit breaker and electrical distribution panel employing the same

A remote control circuit breaker which includes a first current path and a second current path. The circuit breaker also includes a set of separable main contacts, an operating mechanism for opening and closing the set of main contacts, a trip device in electrical communication with the main contacts, a set of separable latching contacts having an actuator in electrical communication with the trip device. The circuit breaker also includes a by-pass circuit in electrical communication with the trip device. The first current path passes through the main contacts, the trip device, and the latching contacts and the second current path passes through the main contacts, the trip device, and the by-pass circuit.

Remote control circuit breaker with a by-pass lead

A circuit breaker has a set of remotely controllable secondary contacts connected in series with the main contacts which provide overcurrent protection. The secondary contacts are opened and closed by a latching solenoid having a close coil and an open coil which are separately connected to switched terminals of a first switch. A voltage source, which may be ac, dc or pulsed, is connected to the common terminal of the first switch through a rectifier. The first switch is coupled to the plunger of the latching solenoid which opens and closes the set of secondary contacts and enables the coil which operates the set of secondary contacts to the opposite state. Energization of the enabled coil is completed by additional, remotely located switches connected between each coil and ground. A status line connected to one of the switched terminals of the first switch is energized when the associated coil is enabled to indicate the open/close status of the set of secondary contacts.

Remotely controllable circuit breaker

A reverse fed single pole miniature ground fault circuit breaker includes a housing, a line termination on the lower portion of the housing, and a load termination on the upper portion of the housing. Separable contacts are disposed between the line termination and the load termination. A handle and operating mechanism form a manual mechanism for manually operating the separable contacts. The handle has an upper position in which the separable contacts are closed and a lower position in which the separable contacts are open. A ground fault circuit interruption trip circuit opens the separable contacts in response to predetermined ground fault current conditions and is powered through those separable contacts. In this manner, when a power source is electrically interconnected with the line termination on the lower portion of the housing, when the handle is in the upper position, and when there is none of the predetermined ground fault current conditions, the ground fault circuit interruption trip circuit receives power through the separable contacts.
