The 2-1393117-3 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), with DC coil voltage range of 5–110 VDC and AC coil voltage range of 12–240 VAC at 50/60 Hz, and Class B coil insulation for enhanced reliability. The relay offers flexible mounting options including panel, DIN rail, and PCB sockets, with optional push-to-test buttons and indicator lamps for improved usability. Key electrical characteristics include coil resistance values ranging from 21 O to 10,000 O (±10%) and rated coil power from 1.2 W to 2.9 W depending on configuration, with initial dielectric strength of 1200–2200 Vrms between contacts and coil. Operating temperature range is -45°C to +70°C for DC coil and -45°C to +45°C for AC coil, with an ambient protection rating of RTI dust-protected per IEC 61810. This relay is ideal for vending machines, commercial sewing equipment, robotics, welding systems, HVAC controls, and medical devices where reliable switching and multiple contact arrangements are required.
