NTE Electronics, Inc. Relay, Spdt, 250Vac, 24Vdc, 20A; Contact Configuration Nte Electronics R47-5A15-120

The R47-5A15-120 is a single pole double throw relay designed for switching motor, lamp, heater, and appliance loads. It features a panel mount with a 1.710 in (43.43 mm) maximum height and uses .250 in (6.35 mm) quick-connect terminals for the load and .187 in (4.75 mm) terminals for the coil. The contact rating is 20A at 250VAC (resistive load) and 10A at 240VAC (inductive load), with a 1HP rating at 120VAC. Contacts are made of AgSnO2, with a contact resistance of 75mΩ at 1A and 5VDC or 12VAC. The 120VAC coil operates with a maximum pickup voltage of 80% of nominal and a minimum drop-out voltage of 30%. It meets a dielectric strength of 2500Vrms and an insulation resistance of 1MΩ minimum. The relay weighs approximately 1.16 oz (33 grams) and has a mechanical life of 5,000,000 operations. It operates from -10°C to +55°C.
