The AZ2280-1C-6DF is a 40 ampere miniature power relay manufactured by American Zettler, featuring a single Form C (SPDT) contact arrangement with quick-connect leads for both contacts and coil. This relay is rated for maximum switched power of 840W or 11,080VA with a maximum switched voltage of 277VAC or 28VDC, and delivers 20A switching current at 277VAC for general use applications. The relay operates with a 6V DC coil (must operate at 4.5V, maximum continuous 7.8V) with a nominal current of 150mA and coil resistance of 40 ohms, providing fast response times of 15ms maximum operate time and 10ms maximum release time. It features a mechanical life expectancy of 1×107 operations and electrical life of 1×105 operations at 28A and 277VAC, with dielectric strength of 1500Vrms contact-to-contact and 2500Vrms contact-to-coil. The relay is housed in a P.B.T. polyester enclosure with tinned copper alloy quick-connect terminals, operates across a wide temperature range of -55°C to 85°C, and is UL Class F rated (155°C), making it suitable for industrial control, HVAC systems, and general-purpose switching applications requiring reliable miniature relay performance.
