Abstract: A solid state motor starter, commonly referred to as a soft starter, is constructed in a manner to be easily manufacturable while at the same time combining all the required components in a relatively small package. A solid state power switch is clamped between a pair of bus bars in an offset manner to accommodate a discrete switching relay mounted in an inverted manner between the line input and the bus bar in communication with the load outputs. When in a motor run mode, current is shunted away from the solid state power switching device and through the switching relay, a substantially linear current path is achieved to reduce power loss and heat buildup. The arrangement allows for a heat sink mounted to one of the bus bars with adequate spacing between the heat sink and the discrete relay for insertion of a cooling fan. Current sensing is achieved with a Hall effect sensor mounted to the bus bar in a small current sensing region that is created by having a pair of slots in the bus bar to direct current. A pair of magnetic pins extend perpendicular from the bus bar to create the magnetic flux for the Hall effect sensor to sense current flow through the current sensing region. The Hall effect sensor circuit board also contains a thermistor which is mounted with adequate insulation yet in thermal communication with the bus bar.

The flux concentrator includes main sections which are formed of a magnetic material. One or more intermediate sections, formed of a nonmagnetic material, extend between the main sections of the magnetic flux concentrator.

Abstract: An electromagnetic starter with an overload relay having magnetic flux shielding is disclosed for use in industrial contactor applications. The starter includes a multi-pole DC controlled contactor which is interlockingly coupled to an overload relay. The overload relay has a simplified interlocking connection to the contactor, which when made, corresponds to an abutting electrical connection between the contactor and the overload relay also being made. The contactor further has a guiding pin that promotes even contact closure within the contactor.

Abstract: The present invention provides an electrical isolation apparatus having independently controllable contactors. The isolation apparatus includes a contactor for each phase or pole of an electrical device as well as each phase or pole of a load. Each contactor is constructed so that each includes multiple contact assemblies that may be independently controlled to open and close. Moreover, the contactors within a single contactor assembly or housing can be independently controlled so that the contacts of one contactor can be opened without opening the contacts of the other contactors in the contactor assembly. Additionally, the contactors are construct and controlled such that a single line side contactor and a single load contactor open simultaneously when an open circuit condition is desired.

Abstract: A motor starter thermal-compensation control is disclosed in which an ambient temperature sensor is positioned to sense ambient temperature and provide an ambient temperature signal in a motor starter. Additional temperature sensors are mounted in thermal communication with each bus bar in a motor starter and to monitor the temperature of each pole. A microprocessor is connected to each of the temperature sensors and periodically receives the temperature signals to monitor change in operating temperature of the motor starter. The control adjusts the output of the motor starter based on the change in the operating temperature so as to maintain a constant output as the ambient temperature increases, or the internal resistance of the device increases with temperature increase. In order to adjust the output, the system increases the FLA ampacity to compensate for the temperature increase. If the ampacity reaches the device's limits, the starter is prevented from engaging the motor with the power supply until it has sufficiently cooled down. The control calculates an estimated cool down time and displays the cool down time to prevent unnecessary start attempts during cool down.

Abstract: A magnetic flux concentrator shield is disclosed for use with magnetic flux sensors in an overload relay for multiple pole electromagnetic contactor applications. The magnetic flux concentrating shield has slotted layers of laminated members. The layers have a series of pole shielding slots which concentrate magnetic flux generated by conductors carrying current through conductor apertures in each layer. Magnetic flux sensors are positioned within air gaps within each pole of the shield. By shielding the generated magnetic flux from reaching the magnetic flux sensor of another pole, the pole shielding slots minimize cross pole magnetic flux sensor interference.

Abstract: A switch has contacts constructed so that an electro-dynamic force is created by the current flowing through the switch which tends to maintain the switch in a closed state. This force counteracts other electro-dynamic forces which tend to open the switch. The contact design is particularly adapted from use in a single pole-double throw switch having a contact arm that is movable between two fixed contacts. The electro-dynamic force compensation exists between the contact arm and whichever one of the fixed contacts the contact arm is against. The fixed contacts also include arc runners so that any arc that develops as the contacts separate eliminates electro-dynamic force which tends to maintain the switch in a closed state.

Abstract: A plate pivotally mounted to a padlock hasp adjacent a reciprocally movable operator handle is pivotable from a stored position to one covering the opening of the hasp, the plate having a hole aligned with the opening and smaller than the opening to receive the shackle of a single, scissors-type safety lockout and maintain the shackle in position to block movement of the operator handle to an operated position. The hole is preferably rectangular to conform to the flat, thin shape of the safety lockout shackle to maintain the shackle properly oriented. An additional round hole for a smaller diameter padlock shackle may be provided in said plate.
