The AGASTAT GP series 10A Control Relay with non-latching, latching and timing versions. AGASTAT control relay is operated by a moving core electromagnet whose main gap is at the centre of the coil. The coil provides a low mean turn length and also assists heat dissipation. Since the maximum travel of the electromagnet does not provide optimum contacts movement, an ingenious amplifying device has been designed. When the centre of the W is moved vertically the lower extremities move closer to each other as can be seen in the illustration. The centre of the W mechanism is connected to the moving core of the electromagnet and the two lower points are connected to the moving contacts. Two of these mechanisms are placed side-by-side to actuate the four contacts sets of the relay. These arms act as return springs for their corresponding contacts. The plastic dust cover has two windows to facilitate cooling and also to allow direct mounting of the relay.
