Schneider Electric TeSys D Contactor 3P 12A AC3 24V DC 1NO+1NC LC1D12ABL

The Schneider Electric LC1D12ABL is a high-performance contactor from the TeSys D series, designed for reliable switching of motors and other loads in industrial and commercial applications. With 3 normally open main poles and a rated operational current of 12 A in AC-3 category (up to 440 V), this contactor is ideal for controlling three-phase motors. The control circuit operates on 24 V DC, ensuring compatibility with modern control systems. Built to last, it offers mechanical durability of 15 million cycles and electrical durability of 2 million cycles under AC-3 conditions. The compact design supports both rail and plate mounting, making it easy to integrate into control panels.

Advantages

High reliability and long service life reduce maintenance costs. The integrated auxiliary contacts (1 NO + 1 NC) eliminate the need for additional components in many applications. The IP20 protection on the front face ensures safe operation in standard industrial environments. Compliance with IEC, UL, and CSA standards guarantees global acceptance.

Suitable for

• Motor starting and switching in AC-3 applications (e.g., pumps, fans, compressors)
• Resistive and inductive load switching in AC-1 applications
• Industrial automation and control panels
