Schneider Electric TeSys K LC1K1201B7 Power Contactor 12A 3P 1NC 24V AC Coil

The Schneider Electric TeSys K LC1K1201B7 is a high-performance 3-pole power contactor engineered for demanding motor control and switching tasks. This compact device is specifically designed to handle currents up to 12A in AC-3 applications, ensuring reliable operation in industrial environments. Featuring a 24V AC control coil and one normally closed (1NC) auxiliary contact, it integrates seamlessly into various control systems where space is at a premium.

Advantages

The primary benefit of this contactor is its exceptionally compact footprint, which allows for efficient use of space in crowded control panels and electrical cabinets. Its robust construction ensures long-term reliability and consistent performance under standard industrial conditions. The inclusion of secure box terminal connections simplifies the installation process and provides a stable, vibration-resistant electrical connection, reducing the need for frequent maintenance.

Suitable for

• Industrial automation systems
• Motor control circuits
• Switching resistive and inductive loads
• HVAC control panels
• Small machinery and equipment control

When it may not be suitable

This contactor is not intended for high-power applications exceeding its 12A AC-3 rating. It is also not suitable for DC control voltage circuits, as it is specifically designed for a 24V AC coil.

Key specifications

• Number of poles: 3
• Rated operational current: 12A (AC-3)
• Control circuit voltage: 24V AC
• Auxiliary contact configuration: 1 normally closed (1NC)
• Connection type: Box terminals

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The contactor is designed for mounting on a standard DIN rail or via screw fixing on a mounting plate. Ensure that the control circuit is connected to the A1 and A2 terminals using a 24V AC power source. Power cables should be securely fastened into the box terminals, ensuring proper torque is applied to prevent overheating or loose connections.

What to consider before purchase

• Verify that your control system provides a 24V AC signal.
• Ensure the 12A current rating is sufficient for your specific motor or load.
• Check available space in your enclosure to confirm the compact dimensions are appropriate.
• Confirm the auxiliary contact configuration meets your feedback or interlocking requirements.

Usage recommendations

Regularly inspect the terminal connections for tightness and check for any signs of debris or dust accumulation within the enclosure to maintain optimal performance and safety.
