The APEM Panel Switches KL372AKXA226N is a single-pole, 20A autoswitch engineered for demanding industrial environments. This switch delivers exceptional reliability through its IP68 sealing, 1,000 MΩ minimum insulation resistance at 500 VDC, and 2,000 Vrms dielectric strength at 50 Hz. Designed for extreme conditions, it operates within a temperature range of -40°C to +85°C and features patented intuitive ergonomics, laser-etched symbols, and optional IP69K front panel sealing for salt spray resistance up to 96 hours. The switch supports 150,000 mechanical cycles and is constructed with silver contacts for low contact resistance and long service life.
The KL372AKXA226N meets stringent environmental standards with IP68 sealing for front panel components (IEC 60529) and optional IP69K sealing for salt spray resistance up to 96 hours (IEC 512-6, test 11f). This ensures reliable operation in wet, dusty, or corrosive environments without compromising performance.
Engineered for high reliability, the switch provides 1,000 MΩ minimum insulation resistance at 500 VDC and 2,000 Vrms dielectric strength at 50 Hz between terminals. Initial contact resistance is 10 mΩ maximum, ensuring efficient current flow and minimal energy loss during operation.
With a mechanical life of 150,000 cycles minimum, the KL372AKXA226N is built to withstand repeated use in industrial settings. The switch operates within a wide temperature range of -40°C to +85°C, making it suitable for extreme conditions.
The patented intuitive ergonomics and laser-etched symbols enhance usability while ensuring clear identification. Available in a wide range of colors and with illuminated or non-illuminated options, the switch balances functionality with user-friendly design.
