The Model 553 Re-Acceleration Relay is designed to take the place of a voltage sensing relay and two time delay relays. When voltage is applied to the product, and the external switch is closed, the adjustable on-delay time begins. After the delay period, the contacts will close.
If the line voltage drops below 90 volts, the contacts open and the true-off delay begins. If the voltage rises above 102 volts before the true-off delay has elapsed, the contact will re-close.
If voltage is not restored to 102 volts before the true-off delay time-period ends, the contacts will remain open until the external start switch is closed.
The product requires a standard eight-pin socket for mounting.
