The 631NH is a single-pole toggle switch with an insulated black polyamide lever and screw terminals, designed for high-amperage panel-mount applications. It features a robust mechanism with a 28° angle of throw in the ON position and OFF position, delivering reliable switching performance with an electrical life of 10,000 cycles at full load. The switch is rated for peak current of 30 A maximum during 1/2 sine at 250 VAC, with initial contact resistance of 10 mO maximum and insulation resistance of 1,000 MO minimum at 500 VDC. Dielectric strength is rated at 2,000 Vrms 50 Hz minimum between terminals and 2,500 Vrms 50 Hz minimum between terminals and frame. The switch operates over a temperature range of -20°C to +55°C and is UL, CSA, and NF-VDE (EN 61058-1) approved, making it suitable for industrial control panels, power distribution equipment, and other demanding switching applications requiring high current capacity and safety certifications.
