TeSys D power contactor AC3 18A 3P 1NO 1NC 48VDC coil LC1D18ED

TeSys D Contactors – Reliable Motor Control

This three-pole TeSys D power contactor is designed for efficient motor control. The rated operational power for AC-3, at 400V, is 7.5 kW, and the rated current is 18A, making it an ideal solution for a wide range of industrial and commercial applications. The contactor's construction is based on solid screw connections, guaranteeing safe and durable electrical connections.

This contactor is distinguished by its high reliability and durability, confirmed by the ability to perform up to 1.5 million switching cycles – a value significantly exceeding market standards. Built-in auxiliary contacts (1NO+1NC) in a mirrored configuration increase the functionality of the device and allow for direct use in safety circuits in accordance with IEC standards. Additionally, the compact dimensions (45 mm width) facilitate mounting both on DIN rails and with screws.

Application and benefits

The TeSys D contactor works perfectly in applications requiring frequent switching of the load, such as:

• Industrial plants: controlling drive motors of machines and equipment.
• Commercial buildings: HVAC systems (heating, ventilation, and air conditioning), elevators and lifts.
• Infrastructure: water and wastewater pumping, emergency power systems.
• Mining and heavy industry: applications requiring high resistance to environmental conditions.

It is worth emphasizing compliance with IEC 60335-1, which confirms increased resistance to fire and dust – important in many working environments. Thanks to the Green Premium label, the product meets stringent environmental standards (RoHS/REACh), supporting sustainable development and a responsible approach to the environment.

Construction and characteristic features

The TeSys D contactor is characterized by its versatility – the same additional equipment can be used for contactors with different current ranges (from 9A to 150A), which simplifies the design process and storage of spare parts. The 48V DC coil provides reliable control, and the availability of technical documentation online using a QR code facilitates installation and servicing of the device. Additionally, the contactor is compatible with a wide range of accessories, allowing it to be adapted to specific application requirements. The rated operating current for AC-4 is 9A at 4kW, which expands the scope of its applications to loads requiring frequent switching on and off.
