TeSys D power contactor AC3 12A 3P 1NO 1NC 110VAC coil LC1D12F7

Power contactor – reliable motor control

This three-pole power contactor from the TeSys D series is designed for efficient motor control. A rated operating power of 5.5 kW at 400V AC-3 makes it an ideal solution for a wide range of industrial and commercial applications. A rated current of 12A at 400V AC-3 ensures stable operation even under loads requiring higher starting current.

The contactor design includes three main normally closed contacts, one normally open (NO) auxiliary contact and one normally closed (NC), providing flexibility in control circuit configuration. Screw connection ensures secure and durable wire connections. The contactor is designed to operate with a control voltage of 110V AC (50/60Hz), making it compatible with most standard electrical installations.

Advantages and design features

• High reliability: Designed for frequent operations – up to 3600 cycles per hour – while maintaining stable operation at temperatures up to 60°C.
• Compact dimensions: A width of only 45 mm makes it easy to mount in tight spaces, both on a DIN rail and with screw mounting.
• Built-in auxiliary contacts: Standardly equipped with a mirrored NO and NC contact, simplifying the design of safety circuits in accordance with IEC standards. Auxiliary contacts are adapted to signals with a minimum current of 1 mA, allowing them to be connected directly to PLCs
• Compliance with standards: Meets the requirements of many standards (IEC, UL, CSA, CCC, EAC, Marin e), guaranteeing safety and compatibility in various environments.
• Durability: Mechanical endurance of 15 million switching cycles ensures long-lasting and trouble-free operation. This is significantly more than the competition offers (usually 1.0-1.2 million cycles).
• Accessory universality: The same additional accessories are compatible with contactors from 9A to 150A, simplifying inventory management and reducing operating costs.
• Sustainable development: The product has a Green Premium certificate, which means compliance with environmental protection regulations (RoHS/REACh) and transparency regarding environmental impact.

Applications

This contactor finds application in a wide spectrum of applications:

• Control of electric motors in industrial plants and machines.
• Heating, ventilation and air conditioning (HVAC) systems.
• Building installations – both commercial and residential.
• Water and wastewater management.
• Mining, metallurgical and mineral industries.
• Powering various types of electrical equipment requiring frequent switching on/off.

Thanks to its versatility and reliability, the TeSys D contactor is an optimal solution for professionals and end-users looking for a high-quality component for motor control.
