TeSys D power contactor AC3 9A 3P 1NO 1NC 48VDC coil screw terminals LC1D09ED

TeSys D power contactor – reliability and compactness in motor control

This 3-pole power contactor from the TeSys D series is a robust solution for controlling motors with a rated power of up to 4 kW at 400V AC-3. Designed for operation in demanding industrial conditions, as well as in HVAC installations, it provides reliable switching of circuits. The contactor's design has been optimized for easy installation and operation, and its compact dimensions (45 mm wide) allow for mounting even in tight spaces.

The LC1D09ED contactor is equipped with a 48V DC coil, making it an ideal choice for applications powered by direct current. Built-in auxiliary contacts – 1NO (normally open) and 1NC (normally closed) – increase the functionality of the device, enabling the implementation of various control schemes. The use of auxiliary contacts in a mirrored configuration (NO+NC) allows for direct use of the contactor in safety circuits, in accordance with IEC standards. Wire connection is made using screw terminals, which guarantees a secure and durable connection.

This model is characterized by high mechanical endurance – as many as 15 million switching cycles and the ability to perform up to 3600 cycles per hour. The rated operating current is 9A for AC-3 at 400V and 25A for AC-1 also at 400V. This makes the contactor perfect for applications requiring frequent switching of the load. Compliance with IEC, UL, CSA, CCC, EAC and Marine standards confirms its safety and quality. Additionally, the product meets the requirements of IEC 60335-1 standard, which makes it suitable for use in household appliances and heating, ventilation and air conditioning (HVAC) systems.

• Versatility: Suitable for controlling motors in various industrial and building applications.

• Compact size: Allows mounting in limited space (dimensions: 45 x 77 x 95 mm).

• High reliability: Ensured by high mechanical endurance and compliance with safety standards.

• Easy installation: Thanks to multi-standard screws and a clear terminal layout.
