The AZ755-1C-5DE is a 20 amp miniature power relay manufactured by American Zettler, featuring a Form C (SPDT) contact arrangement with a 5VDC nominal coil voltage. This relay is rated for maximum switched power of 480W or 5540VA with a maximum switched current of 20A and maximum switched voltage of 150VDC or 277VAC. The relay has a coil resistance of 47 ohms (±10%), a must-operate voltage of 3.6VDC, and a maximum continuous voltage of 9.4VDC, with typical operate and release times of 15ms and 5ms respectively. It offers excellent electrical life expectancy of 1×105 cycles at 16A 240VAC resistive load, mechanical life of 1×107 operations, and operates reliably across an ambient temperature range of -40°C to 85°C. The relay is commonly used in industrial control systems, HVAC equipment, and switching applications requiring compact, reliable miniature relay performance.
