Abstract: A system and method for detecting a fault condition by a relay is provided. The system includes means for detecting phase currents through three electrical phases, means for detecting a ground fault current, a processor configured to perform a current-based function based upon at least one of the phase currents and a filter. The processor is configured to perform current-based functions based on whether the filter is enabled or disabled.

Abstract: An electromagnetic contactor is taught having an E-shaped movable magnetic armature and a complementary E-shaped permanent magnet. The outboard legs of the E-shaped members abut at closure. Each of the central legs of the complementary magnetic members have significant magnetic material removed from the face thereof leaving complementary abutting nipples or protrusions which mate or make with each other as the outer legs make or mate with each other. The total reluctance of the magnetic system when in the abutted state is significantly lower than if the air-gap material had not been removed. This allows the kickout spring to operate effectively to separate the magnets at an appropriate time. The lower the magnetic reluctance the higher the residual magnetism and the more difficult it is for the kickout spring to separate the magnetic members and thus the contacts of the contactor during an opening operation. The central nipple portions or protrusions abut against each other to prevent longitudinal movement of one magnetic central leg member relative to the other. This reduces wear and noise. This is particularly important when the magnets are maintained in the closed state by the utilization of an assisting HOLD pulse which is continuously supplied to the electromagnet.

Abstract: A system and method for detecting a fault condition by a relay is provided. The system includes means for detecting phase currents through three electrical phases, means for detecting a ground fault current, a processor configured to perform a current-based function based upon at least one of the phase currents and a filter. The processor is configured to perform current-based functions based on whether the filter is enabled or disabled.

Abstract: A technique is provided for controlling and protecting loads such as electric motors. In the technique, current sensing circuitry detects electrical current applied to the load. Device thermal modeling circuitry, such as circuitry for modeling heating of a motor, determines heating based upon the sensed current, and generates a first trip signal in a first range based upon the current. Conductor thermal modeling circuitry estimates heating of conductors that supply current to the load, and generates a second trip signal in a second range based upon the conductor heating. The system provides an extended range of operation for a wide range of loads by effectively modeling conventional thermal overload and instantaneous trip devices.

Abstract: A technique is provided for controlling operation of motors of different sized or ratings. Components used to apply and interrupt current to the motors may be shared in control devices for the different motors. The components may include contactors or circuit interrupters, and instantaneous trip devices. The components may be sized for the higher rated motors, and be oversized for the lower rated motors. Control circuitry permits the devices to be controlled in accordance with the characteristics of the particular motor to which the devices are applied, providing accurate circuit interruption while reducing the number of different components and component packages in a product family for the various motors.

Abstract: A mechanically normally open low voltage switch is connected between ground and the high impedance input of a low voltage electronic circuit fed by a low voltage source through a low impedance resistor. With the switch open, current flows into high impedance input of the electronic circuit to provide the electrically normally closed function. When the switch is actuated to the closed position, the high impedance input is pulled down to ground to provide the switch open function.
