The APEM Panel Switches 6646-03LMK-2V is a double-pole autoswitch engineered for high-reliability industrial control systems. This switch delivers precise electrical switching with a nickel-plated bushing, lever, and upper nut finished in bright chrome, providing a durable and corrosion-resistant interface. Its front panel sealing with one O-ring and sealing washer ensures environmental protection, while the double-pole configuration allows for simultaneous control of two circuits. The switch operates within a wide temperature range of -40 °C to +85 °C and meets stringent electrical specifications including 1,000 MΩ min. insulation resistance at 500 VDC and 2,000 Vrms 50 Hz dielectric strength between terminals.
The APEM Panel Switches 6646-03LMK-2V delivers robust electrical performance with a minimum insulation resistance of 1,000 MΩ at 500 VDC and dielectric strength of 2,000 Vrms 50 Hz between terminals. This ensures reliable operation in high-voltage environments while maintaining safety margins. The switch also features an initial contact resistance of 10 mΩ max., minimizing power loss during switching operations.
Engineered for extreme conditions, the switch operates across a temperature range of -40 °C to +85 °C, making it suitable for both cold and hot industrial environments. Its front panel sealing with a single O-ring and sealing washer provides effective protection against dust and moisture, ensuring long-term reliability in harsh settings.
The switch is designed with a maximum panel thickness of 5 mm, ensuring compatibility with standard industrial panels. The torque specification of 1.50 Nm (1.10 Ft.lb) max. applied to the nut guarantees secure installation without damage, while the locking levers provide two secure positions for precise control.
This double-pole autoswitch is ideal for industrial control panels where reliable switching of two circuits is required. Its quick connect terminals simplify installation and maintenance, while the bright chrome plating enhances visual identification and corrosion resistance in demanding applications.
