The APEM Panel Switches 6649-03LM delivers high electrical reliability with an insulation resistance of 1,000 MΩ min. at 500 VDC and dielectric strength of 2,000 Vrms 50 Hz min. between terminals and 3,000 Vrms 50 Hz min. between terminals and frame. This ensures robust protection against electrical faults and high-voltage transients in industrial settings.
Engineered for extreme conditions, the switch operates across a wide temperature range from -40 °C to +85 °C. Its nickel-plated bushing, lever, and upper nut, combined with bright chrome-plated finishes, provide excellent corrosion resistance and long-term mechanical stability in harsh environments.
The switch features a panel thickness of 5 mm max. and requires a maximum torque of 1.50 Nm (1.10 Ft.lb) when tightening the nut. This ensures secure installation without compromising the switch's operational integrity.
With an initial contact resistance of 10 mΩ max., the switch ensures minimal voltage drop during operation. The electrical life of 10,000 cycles at full load guarantees long-term reliability in high-demand applications.
