TeSys D power contactor AC3 18A 3P 1NO 1NC 24VDC coil LC1D186BD

Power contactor for motor control – reliability and compact size

This three-pole TeSys D power contactor, designed for motor control, offers a rated current of 18A in AC-3 category at 400V, which translates to a power of 7.5kW. It provides effective and safe switching of motor circuits in various industrial and construction applications. Equipped with a 24V DC coil, this contactor is ideal for systems powered by direct current.

Design and application

The LC1D186BD contactor is characterized by a compact design (width 45mm, height 77mm, depth 95mm), which facilitates installation even in limited spaces. It has built-in auxiliary contacts – 1NO (normally open) and 1NC (normally closed) – which increases its functionality and eliminates the need for additional auxiliary contact blocks in many applications. Screw terminals provide secure and durable wire connections. Designed to operate at a frequency of up to 3600 cycles per hour at an ambient temperature of up to 60°C, it guarantees long-lasting and reliable operation.

Advantages and benefits

• Versatility: Suitable for controlling motors in various industrial, construction and HVAC applications.
• Compact size: Allows installation in tight spaces.
• Built-in auxiliary contacts: Reduce costs and simplify wiring.
• Low coil power consumption DC: Reduces energy consumption and minimizes the risk of overheating.
• Compliance with standards: Meets the requirements of IEC, UL, CSA, CCC, EAC and Marine, ensuring safety and compliance with regulations.
• Green Premium: A product compliant with RoHS/REACh standards, confirming its ecological character and care for the natural environment.
• Durability: Mechanical endurance of 15 million switching cycles guarantees long device life.
• Wide range of control voltages: Provides flexibility in choosing the right model for a specific application (in this case 24V DC).
