Schneider Electric K2A001ALH Harmony K

The Schneider Electric K2A001ALH is a reliable 1-pole cam switch from the Harmony K line, engineered to provide robust ON/OFF functionality with high current capacity and durable construction. Ideal for industrial and panel-mounted applications where dependable switching and clear operation are required.

Key Features & Benefits

• 1-Pole, 2-Position Switch (0-1)
  Offers two stable positions (“0” = OFF, “1” = ON) with a 45° switching angle. 

• Rated for 20 A Conventional Free-Air Current
  Handles up to 20 A under free-air thermal current conditions. 

• Multifixing, Front-Mount Design
  Features a front plate of 45 × 45 mm with “multifixing” mounting style, allowing flexible installation. Black 35 mm rotary handle with metallic legend “0-1”.

• High Insulation & Voltage Ratings
  Rated insulation voltage (Ui) of 690 V, pollution degree 3. Suitable for industrial power circuits.

• Durability & Mechanical Life

  • Mechanical life: ~ 1,000,000 cycles

  • Electrical durability varies by load type (e.g. AC-15, AC-3, etc.) for many thousands of cycles.

• Protection & Physical Details

  • Protection rating: IP40 (front) — adequate for protection against solid objects, less so for liquids.

  • Dimensions: approx. 45 mm × 45 mm × 77 mm (width × height × depth)

  • Weight: ~ 0.103 kg

• Temperature & Environmental Endurance

  • Operating ambient temperature: -25 °C to +55 °C

  • Storage: -40 °C to +70 °C

  • Resistance to shock and vibration: meets relevant IEC standards (e.g. vibration ~5 gn, shock ~30 gn)

Technical Specifications (Summary)

Ideal Applications

• ON/OFF switching for industrial panels or machinery where a single position selector is sufficient

• Control circuits in automation setups needing reliable, clearly labelled switching

• Replacement of older switches in control cabinets or equipment using standard mounting cut-outs

• Environments where moderate exposure to dust or inert solids exists, but not heavy moisture or splash
