The APEM Panel Switches 6646-03K-2V/3 is a double pole autoswitch designed for robust industrial applications. Featuring 1,000 MΩ min. insulation resistance at 500 VDC, 2,000 Vrms dielectric strength, and 10 mΩ max. initial contact resistance, this switch ensures reliable operation across extreme temperatures (-40 °C to +85 °C) and high electrical demands. Ideal for demanding environments requiring precise switching control.
The APEM Panel Switches 6646-03K-2V/3 is a double pole autoswitch engineered for high-reliability industrial use. This switch delivers exceptional electrical performance with a minimum insulation resistance of 1,000 MΩ at 500 VDC and a dielectric strength of 2,000 Vrms (50 Hz) between terminals, ensuring robust protection against electrical faults. Its low initial contact resistance (10 mΩ max.) and electrical life of 10,000 cycles at full load make it suitable for continuous operation in harsh conditions. The switch operates within a wide temperature range of -40 °C to +85 °C, providing stability in extreme environments. With a black finish on the actuator and bushing, this model combines durability with a professional aesthetic for seamless integration into industrial control panels.
The APEM Panel Switches 6646-03K-2V/3 delivers high electrical reliability with a minimum insulation resistance of 1,000 MΩ at 500 VDC and a dielectric strength of 2,000 Vrms (50 Hz) between terminals. This ensures robust protection against electrical faults and transient overvoltages in industrial settings. The switch also maintains low initial contact resistance (10 mΩ max.) and supports 10,000 cycles at full load, critical for applications requiring frequent switching without degradation.
Engineered for extreme conditions, this switch operates within a temperature range of -40 °C to +85 °C, making it suitable for both cold and hot industrial environments. The front panel sealing with one O-ring and sealing washer provides effective protection against dust and moisture, ensuring long-term reliability in harsh conditions without compromising electrical performance.
The switch features a torque specification of 1.50 Nm (1.10 ft.lb) max. for nut tightening, ensuring secure assembly without damage. Its 5 mm (.196) panel thickness provides structural integrity while maintaining compact dimensions for integration into tight spaces. The black finish on the actuator and bushing enhances visual identification and reduces wear in high-traffic areas.
