20547-82 is a 13 Amp 3PDT (triple-pole double-throw) general-purpose plug-in relay with a flanged cover and quick-connect terminals, designed for industrial machine control, energy management systems, and control panels. The relay features a Class F coil insulation system rated for 155°C total temperature, with the coil molded in Rynite® PET for environmental protection and fine wire gauge coils skeined for integrity. It supports DC coil voltages up to 125 VDC with a 24 VDC coil option providing 480 Ohms resistance and 1.2 W nominal power, and operates with an approximate 15 millisecond pickup and release time. The relay is rated for 13 Amp or 1/3 HP at 120 VAC, 13 Amp or 1/2 HP at 277 VAC, and 10 Amp at 28 VDC, with an expected electrical life of 100,000 operations at rated load and mechanical life of 10,000,000 operations. Its 3/16" diameter moveable silver cadmium oxide and stationary fine silver contacts with gold flash plating ensure reliable switching performance across diverse industrial applications.
