TeSys D power contactor AC3 80A 3P 1NO 1NC 42VAC coil screw terminals LC1D80D7

TeSys D Contactors – Reliable Motor Control

The TeSys D power contactor is a component designed for reliable motor control in demanding industrial and construction applications. Model LC1D80D7, with a rated current of 80A in AC-3 category, provides effective switching of electrical circuits. The contactor's construction is based on solid materials and precise workmanship, guaranteeing long-lasting and trouble-free operation.

At the heart of the device is a coil powered by 42VAC, making it an ideal solution for installations using this control voltage. The contactor has three normally closed main contacts and one normally open and one normally closed auxiliary contact (1NO+1NC), allowing for flexible configuration of control and protection circuits. Connection of power and control is done using convenient screw terminals, ensuring secure and durable connections.

Construction and application

The TeSys D contactor has been designed for easy mounting and integration with existing systems. Compact dimensions (127 mm high, 85 mm wide and 130 mm deep) allow for installation in limited space. The device works perfectly in applications such as:

• Control of three-phase motors with a power of up to 37 kW (AC-3, 400V).
• Motor starters in industry, construction and infrastructure.
• Heating, ventilation and air conditioning (HVAC) systems.
• Applications requiring frequent switching of the load (up to 3600 cycles/hour).
• Marine applications thanks to appropriate certificates.

Advantages and benefits

• High reliability: Mechanical endurance of 15 million switching cycles guarantees long device life even in intensively used applications.
• Versatility: Possibility of use in a wide range of industrial and construction applications.
• Safety: Compliance with many standards (IEC, UL, CSA, CCC, EAC, Marine) ensures safe use and compliance with applicable regulations.
• Easy mounting: Screw terminals facilitate connection of power and control wires.
• Integrated auxiliary contacts: Allow direct use of the contactor in safety circuits according to IEC standard thanks to the mirrored contact arrangement (NO+NC).
• Durability: Made of silver-nickel alloy ensures high electrical conductivity and corrosion resistance of the main contacts.
• Sustainable development: The product meets Green Premium requirements – RoHS/REACH compliance and transparency of information about environmental impact.

The TeSys D LC1D80D7 contactor is a solid solution for professionals looking for a reliable component for motor control. Its versatility, durability and compliance with standards make it an ideal choice for a wide range of industrial and construction applications.
