Abstract: A circuit interrupter includes a digital trip unit containing a microprocessor. The circuit interrupter also includes current transformers for sensing current flow through the contacts of the interrupter and for providing operating power to the trip unit. The current transformers monitoring current flow through the breaker and control potentiometers receiving operator-entered values of the product of line voltage and power factor are connected to the microprocessor to supply it with the values needed to compute real power flow through the interrupter and to display the numeric value of this power flow. The power flow is compared to an operator-entered limit value of peak demand power, and an alarm signal is generated whenever power flow exceeds the limit value peak demand. Integration capability is also provided to calculate energy flow through the contacts in megawatt hours and to present the numeric value of this energy flow.

Abstract: A current limiting circuit breaker includes two parallel pivoting contact arms carrying contacts at the ends thereof. The upper arm is double pivoted and is operated by a mechanism between open and closed positions. A magnetic drive slot motor device surrounds the lower arm and operates during extreme overcurrent conditions to draw the lower arm down and aid in rapidly separating the contacts. An arm positioning assembly is spring loaded to bias the lower arm toward a closed circuit position and provide contact closing force, the upper limit of travel being set by a rod extending through the end of the lower contact arm to abut against the slot motor.

Abstract: A motor controller having a single set of contacts and two contact operating systems is provided for operation and protection of a motor and the associated circuitry over a complete range of possible currents. For a normal motor starter operation and for fault current up to a predetermined value, an electromagnetic actuator is used to open the contacts a relatively small distance such as 1/4 inch. For higher fault currents a magnetic drive or linear slot motor opens the contacts to a greater spacing such as 1 inch. The slot motor opens the contacts very rapidly giving rise to good current limiting. The disclosed integral motor starter utilizes a bridging contact arm on which are mounted a pair of movable contacts which are aligned to engage a pair of stationary contacts when the disclosed motor starter is closed, completing an electric circuit to the controlled motor.

Abstract: A circuit interrupter having a fixed elongated contact arm, with a fixed contact disposed at the end thereof, and an elongated movable contact arm, with a movable contact disposed at the end thereof, and a magnetic driving device for rapidly separating the contacts. The magnetic driving device is formed of a ferromagnetic material and has a slot formed therein which is magnetically open on one end. The fixed contact arm is partially disposed in the slot near the closed end and the movable contact arm is partially disposed within the slot towards the open end. The magnetic drive or slot motor rapidly separates the contacts upon a predetermined overload. Divergent arc rails lying in the same general plane extend from the fixed contact and the movable contact. A magnetic arc gun or yoke having an opening therethrough disposed around the movable contact, the stationary contact and a portion of the arc rails when used concentrates the arc and provides for rapid arc movement by concentrating the magnetic forces generated by current flow which acts upon the arc.

Abstract: A current limiting circuit interrupter having a movable contact arm disposed within a magnetic drive structure and a pair of contacts disposed within a magnetic arc driving structure is provided. The magnetic drive or slot motor rapidly moves the movable contact arm to separate the contacts upon a predetermined overload. When high overload currents pass through the contactor arm extremely fast separating movement occurs between the contacts providing current limiting. In one embodiment there is provided a pair of relatively stationary spaced apart contacts bridged by an elongated movable contact arm which can be moved away from the stationary contacts to establish two serially related arcs. At each end of the bridging contact there is provided a surrounding magnetic structure or yoke which magnetically impels any arc formed during circuit interruption to move laterally outward into an arc extinguishing structure. The arc extinguishing structure can comprise non-magnetic metallic spaced apart plates. The portion of the contact arm intermediate the ends is disposed within a magnetic drive or linear slot motor. The bridging contact arm is biased toward an open position by a spring and held in a closed position by a magnetic latch. When current exceeds a predetermined value the bridging contact arm is drawn into the slot motor rapidly opening the circuit interrupter. A plurality of T-shaped members are disposed partially within the magnetic arc driving yoke with the bottom portion of T-shaped member disposed in proximity to the contacts within the yoke opening. During circuit interruption the magnetic forces generated within the yoke rapidly move any arc formed off of the contacts into engagement with the bottom portion of the T-shaped plates. The portion of the T-shaped plates which contact the arc can be coated with tungsten for increased life. Since any arc formed during circuit interruption is moved rapidly off the contacts, the contacts can be formed from a material such as silver cadmium oxide, AgCdO, having a very low resistance.

Abstract: A multipole circuit breaker including a latch release actuator having a trip coil and a hold-in coil coaxially surrounding a plunger and mounted within a hollow cylindrical actuator support frame. The actuator is mounted in association with a latch mechanism and includes a spring biasing the plunger toward release of the latch mechanism. The hold-in coil is responsive to voltage conditions on an external control line and serves to oppose the action of the bias spring and maintain the plunger in a position to prevent release of the latch mechanism when the voltage on the control line is above a predetermined level. The trip coil is connected to an electronic sensing circuit which activates the trip coil upon overcurrent conditions through the circuit breaker contacts to cause the trip coil to aid the action of the bias spring and overcome the action of the hold-in coil to move the plunger into engagement with the latch mechanism, effecting release of the latch mechanism and separation of the circuit breaker contacts.
