HE1AN-W-DC9V-Y7 is a high-capacity power relay designed for demanding industrial switching applications requiring reliable performance at elevated current levels. This 1 Form A relay features a maximum switching current of 120A at 480V AC, with a compact protective construction measuring 50mm × 40mm × 43mm and AgNi contact material rated for 120A continuous carrying capacity. The relay operates at a 9V DC coil voltage with a maximum operate voltage of 6.75V (75% of rated), a coil resistance of 32.4O, and a rated operating power of 2,500mW, while maintaining a minimum contact gap of 3.6mm and insulation distance of 10.5mm for enhanced safety. With a coil holding power of only 400mW, this relay contributes to energy efficiency in devices such as inverters, battery storage systems, stationary charging stands, and industrial equipment, while offering mechanical life expectancy of at least 1×106 operations and electrical life of 1,000 operations at rated load.
