摘要： Disclosed is a magnetic contactor. The magnetic contactor includes a frame, a bobbin provided in the frame, and configured to include a hollow part, a movable core movably inserted into the hollow part in an axial direction, a yoke disposed at the outer surface of the bobbin to be separated from the coil and to face each other, and configured to act as a fixed core, and a manipulating circuit part disposed at the outer surface of the bobbin in parallel with a moving direction of the movable core to intersect the yoke. The coil is wound around an outer surface of the bobbin. Accordingly, a coil having a broad rated voltage range is used. Also, a structure of a product is simplified, and a space is broadly used.

摘要： An apparatus for tripping a circuit breaker having a trip coil. A trip circuit is coupled at a first node to a first power supply and at a second node to the trip coil. The trip circuit comprises a switch for closing in response to a control signal, a coil coupled to the switch so that current is allowed to flow through the coil when the switch closes, relay contacts operatively coupled to the coil so that the relay contacts close when current flows through the coil, and a zener diode for providing a low impedance path after the relay contacts close and for applying a holding voltage across the coil sufficient to keep the relay contacts closed while current flows through the low impedance path.

摘要： An electronic circuit, and corresponding method, for controlling the closing velocity of electrical switchgear, includes an actuator and a current detection circuit that detects whether an optimum amount of current is flowing through the actuator. When the optimum amount of current is detected, a current optimizing resistor is inserted into the path of the current flowing through the actuator, thus limiting the current flowing through the actuator to the optimum amount. This, in turn, limits the closing velocity of the electrical switchgear and minimizes contact bounce.

摘要： A power supplying apparatus has a control circuit which controls the timing at which at least one electromechanical converting means is connected to a non-regulated power supply, and the timing at which at least one other load is connected thereto. The control of the control circuit is such that the electromechanical converting means is first connected to the non-regulated power supply to instantaneously apply a no-load voltage to the electromechanical converting means. As a result, the electromechanical converting means instantaneously produces a great mechanical force. The subsequent control of the control circuit is such that other loads are further connected to the power supply so as to supply the rated voltage to the loads and to the electromechanical converting means.

摘要： The specification discloses a control circuit for electromagnetic devices and a method of operating such devices in which a higher voltage is supplied for actuating the devices to pull the armatures thereof to attracted position, while a lower voltage is supplied to hold the armatures in attracted position. In the circuit the coils of the electromagnetic devices are connected across a line in series with a voltage-dropping resistor and a bypass around the voltage-dropping resistor is closed automatically when a switch pertaining to a coil to be energized is moved to coil-engaging position.
