TeSys D power contactor AC3 12A 4P 2NO 2NC 230VAC coil LC1D128P7

Power contactor – reliable load control

This four-pole power contactor from the TeSys D series is a robust solution for controlling motors and other loads in industrial and building installations. Designed to operate at 230VAC, it provides reliable switching of circuits, ensuring safety and operational efficiency. This contactor is particularly useful in applications requiring frequent switching, such as heating, ventilation, air conditioning systems, and in production facilities.

Construction and operating parameters

The LC1D128P7 contactor is characterized by its compact dimensions – 45 mm wide, 85 mm high, and 92 mm deep – making it easy to install in tight spaces. It has two normally open (2NO) and two normally closed (2NC) main contacts, as well as an additional NO and NC auxiliary contact, which increases its functionality. The rated operating power for AC-3 is 5.5 kW at 400V, and the rated operating current Ie is 12A for AC-3 and 25A for AC-1. The connection of the main contacts is made using screw connections, which ensures a stable and secure connection of the wires.

Advantages for installers and users

• High mechanical durability: The contactor is adapted for intensive operation, offering up to 1.5 million switching cycles – much more than competitive solutions (usually 1.0-1.2 million). This translates to a longer device life and less frequent replacement.

• Built-in auxiliary contacts: Two built-in auxiliary contacts (NO+NC) simplify electrical diagrams and reduce the need for additional components. They allow direct use of the contactor in safety circuits in accordance with IEC standards.

• Universal accessories: The same additional accessories are compatible with contactors from 9A to 150A, which simplifies storage and component selection.

• Compliance with standards: The product meets a number of international standards (IEC, UL, CSA, CCC, EAC, Marine), which guarantees its safety and reliability in various applications.

• Sustainable development: The Green Premium certificate confirms compliance with environmental protection regulations (RoHS/REACh) and transparency in disclosing information about environmental impact.

• Easy installation: Multi-standard screws facilitate mounting and wiring.

• Digital documentation: Access to technical documentation via a QR code allows for quick access to the necessary information.

The TeSys D contactor is an investment in a reliable and durable load control solution that will meet the expectations of even the most demanding users.
