TeSys D power contactor AC3 12A 3P 1NO 1NC 400VAC coil LC1D12V7

Power contactor for controlling motors and electrical circuits

This three-pole TeSys D power contactor, with a rated current of 12A, is designed for reliable control of motors and other electrical loads in industrial and commercial applications. Its compact design and high efficiency make it an ideal solution for both installers and end-users. This contactor is particularly well suited for controlling motors up to 5.5 kW at 400V AC.

Construction and application

The LC1D12V7 contactor has screw connections for the main contacts, which simplifies and speeds up installation. It is equipped with a 400V AC coil (50/60Hz), ensuring compatibility with a wide range of electrical installations. Built-in auxiliary contacts (1NO + 1NC) in a mirrored configuration increase the functionality of the contactor, allowing its use in safety circuits in accordance with IEC standards. It can be mounted on a DIN rail or directly on a surface.

This contactor finds application in many areas, such as:

• Control of three-phase motors up to 7.5 HP at 460V
• HVAC systems (heating, ventilation and air conditioning)
• Pumps and process equipment
• Control cabinets with GV2/GV3 protection
• Applications in buildings and industrial plants

Key features and benefits

• High reliability: Designed for frequent switching – up to 3600 cycles per hour – guaranteeing long-term operation even in demanding conditions.
• Compact size: Only 45 mm wide allows for efficient use of space in control cabinets.
• Versatility: Possibility of mounting on a DIN rail or directly on a surface provides installation flexibility.
• Safety: Built-in auxiliary contacts in a mirrored configuration (NO+NC) allow for the construction of safe control circuits.
• Compliance with standards: Meets the requirements of many standards (IEC, UL, CSA, CCC, EAC, Marin e), confirming its quality and safety of use.
• Durability: Made of high-quality materials providing resistance to environmental conditions and long life. Contacts made of silver alloy ensure reliable current conduction.
• Easy identification: Short catalog number contains information about the rated current (AC-3).

Additionally, TeSys Deca contactors are characterized by increased resistance to fire and dust according to IEC60335-1, which increases safety in difficult industrial conditions. Technical documentation is available online using the QR code placed on the product.
