TeSys D power contactor AC3 18A 3P 1NO 1NC 110VAC coil LC1D18F7

TeSys D Power Contactor – Reliable Motor Control

This three-pole TeSys D power contactor is designed for efficient control of motors up to 7.5 kW at 400 V (AC-3). The rated operating current is 18 A, making it an ideal solution for a wide range of industrial and construction applications. Equipped with an AC 110 V coil (50/60 Hz) and built-in auxiliary contacts 1NO + 1NC, it provides flexibility and reliable operation.

Design and Application

The LC1D18F7 contactor features a compact design (45 x 77 x 86 mm) allowing for mounting on both DIN rail and with screws. Screw connection of the main contacts ensures secure and durable electrical connections. This product is used to control various devices such as pumps, fans, compressors and conveyors. Compliance with IEC 60335-1 guarantees increased resistance to fire and dust, making it a safe choice for installations in buildings and HVAC systems.

Advantages and Benefits

• High mechanical endurance: The contactor provides up to 1.5 million switching cycles, exceeding market standards (competition typically offers 1.0-1.2 million cycles). This translates to a longer service life and less frequent device replacement.
• Built-in auxiliary contacts: It has two built-in auxiliary contacts (NO+NC), eliminating the need for additional components and simplifying electrical diagrams. Mirror NC contacts increase circuit safety.
• Accessory universality: It uses the same additional accessories as contactors from 9A to 150A, making component selection easier and reducing storage costs.
• Wide voltage range: Designed to operate at AC 440 V (50/60 Hz).
• Sustainable development: The product has a Green Premium label, which means compliance with RoHS/REACh regulations and care for the natural environment.
• Easy identification: The short catalog number contains information about the rated current (AC-3), making it easier to select the appropriate model.
• Access to documentation: Technical documentation is available online using a QR code, making installation and servicing easier.
• Data transparency: Available information on environmental impact and instructions for end-of-life management.

Additional information: the rated operating current for AC-1 is 32 A, and for AC-4 – 9 A with a power of 4 kW. This contactor is compatible with GV2 circuit breakers for single-phase motor starting. The main contacts are made of silver-nickel alloy or silver-tin oxide depending on the contactor's rated current.
