Schneider Electric K2B001ULH Harmony K

Upgrade your control panel’s switching capabilities with the Schneider Electric K2B001ULH, a robust cam changeover switch in the Harmony K line. Engineered for dependable performance and rugged use, this 1-pole switch is ideal for industrial and automation applications where clear OFF-ON-OFF switching is needed.

Key Features & Benefits

• 20 A (One-Pole) Changeover Capability
  Rated for 20 A conventional free-air thermal current (1P), making it appropriate for control circuits and moderate power switching.

• Multifixing Front-Mount Design
  Includes a 45 × 45 mm front plate, allowing flexible mounting options (multi-fix). 

• Switching Positions 2-0-1 (Changeover with OFF Position)
  Marked “2-0-1” metallic legend. Provides two ON positions (2 and 1) with an OFF (0) position in between. Useful for safely isolating circuits or selecting between two sources.

• Handle & Operator Details
  Equipped with a 35 mm black rotary handle. No padlocking facility provided.

• Durable & Safe Construction

  • Rated insulation voltage up to 690 V (pollution degree 3) per IEC standards.

  • IP40 protection (front & body) – suitable for indoor environments with minimal exposure to liquid ingress.

  • Mechanical durability: about 1,000,000 cycles under rated use.

• Switching Angle & Positions
  Provides a switching angle of 45°. The “Left” position is approx. 315° from OFF, the “Right” position at 45° from OFF.

• Electrical Ratings & Endurance
  Good performance under various duty categories (AC-15, AC-21, AC-3 etc.), with durability at thousands of cycles depending on usage. Short-circuit rating up to 10,000 A (with proper protection) is noted in datasheets.

• Operating and Environmental Conditions
  Operates safely between –25 °C and +55 °C, with storage from –40 °C to +70 °C. Withstands typical industrial vibration and shock levels.
