Schneider Electric K1A001ALH Harmony K

The Schneider Electric K1A001ALH is a precision 1-pole cam switch from the Harmony K family. Designed for robust industrial control, it offers reliable ON/OFF switching, durable build quality, and compatibility with standard panel installations.

Key Features & Benefits

• Single-Pole, Two-Position (0-1) Switch
  Provides two stable positions: “OFF (0)” and “ON (1)” for simple and intuitive control.

• 12 A Free-Air Thermal Current Rating
  Rated conventional free-air thermal current of 12 A, sufficient for moderate load switching.

• Switching Angle of 45°
  Smooth operation with a compact 45° rotary travel between positions.

• Multi-Fixing, Front Mount Design with 45×45 mm Front Plate
  Allows for versatile mounting in panels; the 45 mm × 45 mm front plate helps streamline installation.

• Black Handle with Clear 0-1 Metallic Legend
  The rotary handle (≈ 35 mm) is black, with “0-1” printed clearly, aiding visual clarity for operators.

• High Insulation & Voltage Endurance
  Rated insulation voltage up to 690 V, pollution degree 3 per IEC 60947-1 standards.

• Durability
  Mechanical life rated to ≈ 1,000,000 cycles under AC-15 usage; slow-break contacts help protect equipment and extend contact life.

• Protection Rating
  IP40 protection (front and body) suitable for indoor panel-mounted use where the switch is not exposed to water or heavy dust.
