The APEM Panel Switches 6649-03K-3V/3 is a double pole autoswitch engineered for industrial control systems. This switch provides a secure ON-OFF-ON electrical function with front panel sealing using one O-ring and sealing washer to protect against environmental contaminants. Its robust construction ensures reliable operation across extreme temperature ranges (-40°C to +85°C) and high electrical demands, making it suitable for critical applications where durability and precision are essential.
The APEM Panel Switches 6649-03K-3V/3 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 between terminals and 3,000 Vrms 50 Hz between terminals and frame. This ensures robust protection against electrical faults and transient overvoltages in industrial settings.
Engineered for extreme conditions, this switch operates within a temperature range of -40°C to +85°C, accommodating both freezing and high-heat environments. The front panel sealing with one O-ring and sealing washer provides effective protection against dust, moisture, and other environmental contaminants.
The switch requires a maximum torque of 1.50 Nm (1.10 Ft.lb) for nut installation, ensuring secure and consistent assembly. Its robust construction supports 10,000 cycles at full load without degradation, making it ideal for applications requiring frequent switching.
Available with a black finish on the actuator and bushing, this switch offers a professional aesthetic while maintaining functional integrity.
