Schneider Electric K63C003AP Harmony Series K

Control power safely and reliably with the Schneider Electric K63C003AP cam switch from the Harmony K product line. Designed for industrial panels and machinery, this 3-pole switch handles high current loads, provides robust insulation, and is engineered for long-term durability.

Key Features & Benefits

• High Current Rating (63 A, 3-Pole Switch)
  Rated for 63 A of conventional free-air thermal current, across 3 poles. Ideal for mains power control and load switching.

• Front-Mounting Design with 64 × 64 mm Plate
  Mounts from the front using a 64 × 64 mm plate (4 holes) for solid panel integration. Black rotary handle provides “0-1” switching positions.

• Rated Insulation Voltage up to 690 V
  Insulation and operational voltage standards comply with IEC/EN 60947-1; suitable for use in three-phase and industrial power systems.

• Switching Positions & Angle
  Two positions: OFF (“0”) and ON (“1”), with a switching angle of 60°, enabling precise control.

• Slow-Break Contacts & Robust Power Capacity
  Switch handles AC-3 and AC-23A duty, with operational power up to ~18.5 kW for 3-phase systems. This switch is built to break current safely under load.

• Durable Construction & Terminations
  Uses captive screw clamp terminals:

  • Flexible conductors: 2 × 10 mm²

  • Solid conductors: 2 × 16 mm²
    Also positive opening of contacts for safety.

• Moderate Protection Rating
  IP40 protection for the enclosure—suitable in environments where solid objects and limited ingress are concerns, but not for water or dust-sealed applications.

• Mechanical Durability
  Rated for ≈ 300,000 mechanical cycles, ensuring long life under repeated use.

• Operating Temperature Range
  -25 °C to +55 °C in operation; storage from -40 °C to +70 °C.
