Designed to take the place of a voltage-sensing relay and two time-delay relays, the Model 553 re-acceleration relay closes the external start switch when voltage is applied and begins its adjustable on-delay time period. After the delay period, the contacts close. If line voltage drops below 90V, the contacts open and the true-off delay begins. If the voltage rises above 102V before the true-off delay has elapsed, the contact will re-close. If voltage is not restored to 102V before the true-off delay time period ends, the contacts will remain open until the external start switch is closed.
