The AZ164-2CT-120A is a miniature heavy-duty power relay designed for AC applications with a 120 VAC nominal coil voltage and DPDT (2 Form C) contact arrangement. It features silver cerium contacts with contact resistance less than 50 milliohms, rated for maximum switched power of 300 W at 2500 VA with a maximum switched current of 10 A and voltage of 250 VAC. The relay operates with a nominal current of 10.0 mA ± 10% and coil resistance of 4,550 ± 10% ohms, with maximum continuous dissipation of 1.7 VA at 20°C. It provides mechanical life expectancy of 2 × 107 operations, operate time of 25 msec maximum, and operates reliably across an ambient temperature range of -55°C to 70°C. The relay is housed in a polycarbonate enclosure with PC board terminals, making it suitable for industrial control, switching applications, and general-purpose relay circuits requiring high reliability and switching capacity.
