The APEM Panel Switches KRR21/4O092810 is a high-reliability autoswitch engineered for demanding industrial environments. This switch combines a unique rocker mechanism with laser-etched symbols for clear identification, offering both illuminated and non-illuminated options. Its exceptional insulation resistance of 1,000 MΩ min. at 500 VDC and dielectric strength of 2,000 Vrms 50 Hz ensure robust electrical performance. The switch operates within a wide temperature range of -40°C to +85°C and supports IP68 or IP69K sealing for extreme conditions, making it ideal for applications requiring high durability and resistance to environmental stressors.
The KRR21/4O092810 delivers reliable electrical performance with a dielectric strength of 2,000 Vrms 50 Hz min. between terminals and an insulation resistance of 1,000 MΩ min. at 500 VDC. It supports 60 W 24 VDC circuits with 10,000 operational cycles, ensuring long-term durability in demanding electrical environments.
Engineered for extreme conditions, this switch offers IP68 or IP69K sealing options. The IP69K rating provides resistance to high-pressure water and harsh chemicals, while the IP68 rating ensures protection against immersion. Additionally, it withstands 96 hours of salt spray testing (IEC 512-6) and vibration up to 10-500 Hz.
Constructed from high-grade materials, the switch features a PA 6-6 case and ABS bezel for durability. Terminals are made from brass with solid silver grain or silver plating (A or S) for optimal conductivity, while gold plating (D) provides enhanced corrosion resistance. Contact rollers are nickel-plated brass for smooth operation.
The switch operates within a wide temperature range of -40°C to +85°C, ensuring functionality in extreme conditions. With an initial contact resistance of 10 mΩ max., it maintains low resistance for efficient current flow. The switch supports 100 W 24 VDC loads with 10,000 cycles for functions 1 & 6, making it suitable for high-reliability applications.
