APEM Panel Switches 669/3 are high-performance four-pole autoswitches engineered for industrial control systems. These switches deliver reliable operation across extreme temperature ranges (-20°C to +55°C) and are designed to withstand high current and voltage demands through their robust construction. Featuring screw terminals, melamine/polyester casings, and nickel-plated brass components, the 669/3 series ensures durability and precision in critical industrial applications where switch reliability is paramount.
The APEM Panel Switches 669/3 operate effectively in a wide temperature range from -20°C to +55°C (-20°F to 131°F), making them suitable for both cold and hot industrial environments. This robust thermal performance ensures consistent functionality without degradation in extreme conditions.
Constructed with a melamine/polyester case, these switches provide excellent resistance to environmental factors. The brass actuators and bushings are nickel-plated for enhanced corrosion resistance, while silver contacts ensure low electrical resistance and long service life in high-demand applications.
Screw terminals are used for secure and reliable electrical connections. The precise torque specification of 1.50 Nm (1.10 Ft.lb) max. applied to nut ensures consistent and safe installation without over-tightening or damage.
