The AZ755-1C-48DE is a 20 amp miniature power relay manufactured by American Zettler, featuring a 48VDC nominal coil voltage with Form C (SPDT) contact configuration. The relay is rated for maximum switched power of 480W or 5540VA at up to 277VAC or 150VDC, with a maximum switched current of 20A. Key performance characteristics include a coil resistance of 4170 ohms (±10%), must-operate voltage of 34.6VDC, maximum continuous voltage of 89.0VDC, operate time of 15ms maximum, and release time of 5ms maximum at nominal coil voltage. The relay offers mechanical life expectancy of 1×107 operations and electrical life of 1×105 operations at 16A 240VAC resistive load, with dielectric strength of 4000Vrms coil-to-contact and 1000Vrms between open contacts. This relay is ideal for industrial control applications, automation systems, and switching applications requiring reliable miniature relay performance with high current capacity.
