描述

The 659H is a three-pole toggle switch from the 600H-600NH series designed for high-amperage panel-mount applications. It features a robust mechanism with a metal nickel-plated brass lever and screw terminals, offering a 28° angle of throw with ON-OFF-ON electrical function across three poles (positions III, II, and I). The switch is rated for a maximum peak current of 30 A during 1/2 sine at 250 VAC, with an initial contact resistance of 10 mO maximum and insulation resistance of 1,000 MO minimum at 500 VDC. It provides dielectric strength of 2,000 Vrms at 50 Hz between terminals and 2,500 Vrms at 50 Hz between terminals and frame, with an electrical life of 10,000 cycles at full load. The 659H is UL, CSA, and NF-VDE (EN 61058-1) approved, making it suitable for industrial control panels, machinery, and equipment requiring reliable high-current switching with multiple independent circuits.
