TeSys D power contactor AC3 12A 3P 1NO 1NC 380VAC coil LC1D12Q7

Power contactor – reliable control of motors and circuits

This three-phase TeSys D power contactor with a rated current of 12A is a robust solution for controlling motors, HVAC systems and various industrial loads. Its compact design combined with high efficiency makes it an ideal choice for both installers and end users. The LC1D12Q7 contactor is compatible with Schneider Electric overload relays, providing comprehensive installation protection.

Design and application

The contactor is designed for easy installation and integration with existing systems. It features screw connections that ensure secure and durable wire connections. The wide range of applications includes controlling motors up to 5.5kW (AC-3, 400V), pumps, process equipment and heating, ventilation and air conditioning systems. Built-in auxiliary contacts (1NO + 1NC) increase the functionality of the contactor and allow direct connection to safety circuits in accordance with IEC standards.

Key features and benefits

• High mechanical endurance: designed for intensive operation – withstands up to 15 million switching cycles.
• Integrated auxiliary contacts: standardly equipped with a mirror set of contacts (NO+NC), which simplifies the design of control and protection circuits. Auxiliary contacts are adapted to work with low-current signals (min. 1mA), allowing direct connection to PLC controllers.
• Versatility: the ability to choose different coil voltages (including 380VAC) ensures compatibility with various power systems.
• Compliance with standards: meets the requirements of IEC60335-1 and other global standards (UL, CSA), guaranteeing safety and reliability.
• Compact size: dimensions 77 x 45 x 86 mm allow easy integration of the contactor in tight installation spaces.
• Easy identification: the short catalog number contains information about the rated current in AC-3 category, which facilitates the selection of the appropriate model.
• Digital documentation: access to technical documentation via QR code facilitates servicing and troubleshooting.
