The 3-1393117-2 is a Potter & Brumfield KUP Series panel plug-in relay designed for general-purpose industrial and commercial control applications. It features multiple contact configurations (1-3 form C), AC coil ratings from 12-240VAC at 50/60 Hz, and DC coil ratings from 5-110VDC, with Class B coil insulation for enhanced reliability. The relay provides initial dielectric strength of 1200Vrms between open contacts, 2200Vrms between contact and coil, and 2200Vrms between adjacent contacts, with insulation resistance of 100MO at 500VDC. Operating temperature ranges from -45°C to +70°C for DC coil enclosed relays and -45°C to +45°C for AC coil 3-pole enclosed relays. This relay is ideal for vending machines, commercial sewing equipment, robotics, welding systems, HVAC controls, and medical devices, offering push-to-test buttons, indicator lamp options, and compatibility with panel, DIN rail, or PCB mounting sockets.
