描述

The AZ4-1CH-6DE is a 40 ampere miniature power relay manufactured by American Zettler, designed for high-current switching applications in industrial and commercial equipment. It features dual-pole contact arrangements (DPST or DPDT) with a maximum switched power rating of 560W or 8310VA, supporting up to 40A on normally open contacts and 3A on normally closed contacts at voltages up to 30VDC or 600VAC. The relay offers multiple coil voltage options (5V, 6V, 12V, 24V, 48V, 110V DC or 12V, 24V, 120V, 220V, 240V, 277V AC) with typical operate time of 15ms and release time of 10ms, ensuring fast response in switching circuits. Contact materials include silver cadmium or silver tin oxide with contact resistance less than 50 milliohms, and the relay is rated for minimum 5×106 mechanical operations and 1×105 electrical operations at 30A/277VAC. This relay is ideal for motor control, HVAC systems, lighting control, and other applications requiring reliable high-current switching with long operational life.
