DESCRIPTION SPECIFICATIONS

nn

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 Model 553, and the external start switch is closed, the adjustable on-delay time begins. After the delay period, the contacts will close.

Model 553 Nominal Voltage 120VAC 60 Hz Trip Point Drop Out 90VAC Trip Point Pick Up 102VAC On Delay 1 to 120 seconds adjustable True Off Delay 1 to 10 seconds adjustable Power Consumption 5 watts typical >

nn

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.

Transient Protection 2500 VRMS for 10msec Repeat Accuracy 0 . 5% Response Time 100 msec Dead Band ѱ 2% >

nn

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.

Contact Rating 10A at 120VAC resistive Expected Relay Life Mech: 10 million operations Elec: 100,000 operations at rated load Operating Temperature +14 to +122ں F Humidity Tolerance 0 to 97% without condensation Enclosure Material Polycarbonate >
