The ATEMNOF is a normally open, quick-acting temperature control switch specifically designed for fan control applications. It utilizes a bimetal temperature sensor within a light gray UL94V-O plastic housing and is a Fahrenheit-based model. The switch has a maximum switching capacity of 15 A resistive at 120 VAC, 10 A resistive at 250 VAC, and 30 W for DC loads, with a minimum load of 20 mA. Connections are made with press-fit terminals for AWG 14 wire, and the unit mounts easily to a 35mm DIN rail. By regulating fan operation, the ATEMNOF prolongs fan life and improves the efficiency of electrical components.
