CA2KN22F7 is a control relay (auxiliary contactor) from Schneider Electric’s TeSys K series, used for control circuits, signal switching, and interlocking applications in industrial panels.

It is designed to control electromagnetic loads and provide multiple auxiliary contacts for automation logic.

⚙️ Technical Description

• Product Type: Control Relay / Auxiliary Contactor
• Series: TeSys K (CA2K)
• Contact Configuration: 2 NO + 2 NC (4 contacts)
• Rated Operational Voltage (Ue): Up to 690 V AC
• Coil Voltage (Uc): 110 V AC, 50/60 Hz
• Rated Current (Ith): 10 A
• Utilisation Category: AC-15 / DC-13 (control circuits)

��️ Key Features

• Provides multiple auxiliary contacts for control logic
• Suitable for high switching frequency operations
• Compact design (approx. 45 mm width)
• DIN rail or panel mounting
• Screw clamp terminals for secure wiring
• High durability (~10 million mechanical operations)

�� Functional Use

• Used in control panels and automation systems
• Ideal for:
  • Interlocking circuits
  • Signal indication
  • Motor control logic
  • PLC interface circuits

�� It does not carry heavy load like MCCB/contactor, but works as a control switching device.

�� Applications

• Industrial automation panels
• Motor starters and control circuits
• Electrical distribution boards
• HVAC and machinery control systems

�� Simple Explanation

This relay acts like a multi-switch controlled electrically:
�� When coil (110V AC) is energized, it changes the state of 2 NO and 2 NC contacts, allowing control signals to operate different parts of a circuit.
