TeSys D power contactor AC1 40A 4P 1NO 1NC 220VDC coil screw terminals LC1DT40MD

TeSys D Contactors – Reliable Control of Electrical Circuits

This TeSys D power contactor, with a rated current of 40A and four poles, is designed for efficient and safe control of motors and other electrical loads. Equipped with one normally open (1NO) and one normally closed (1NC) contact, it provides flexibility in building control circuits. The use of a 220VDC coil guarantees compatibility with DC-powered installations. Screw terminals facilitate quick and secure cable connection.

Design and Practical Application

The LC1DT40MD contactor is intended for a wide range of applications – from industrial installations, through commercial buildings, to HVAC systems. Its robust construction and compliance with IEC60335-1 standard ensure high reliability and safety, especially in environments with increased fire and dust resistance requirements. High mechanical endurance (15 million switching cycles) and integrated auxiliary contacts (NO+NC) make it an ideal solution for applications requiring frequent circuit switching. Additionally, the auxiliary contacts are adapted to work with low-current signals (min. 1mA), allowing their direct connection to PLCs.

Key Features and Benefits for Professionals and Users

• Versatility: Suitable for various applications – from simple home circuits to advanced industrial systems.

• Safety: Compliance with IEC60335-1 standard provides increased resistance to fire and dust, increasing safety.

• Durability: Mechanical endurance of 15 million switching cycles guarantees long device life even with intensive use.

• Easy Installation: Screw connection ensures quick and secure cable connection, minimizing installation time.

• Flexibility: The presence of normally open and normally closed contacts (1NO/1NC) allows the contactor to be adapted to the specific needs of a given control circuit.

• Automation Integration: Auxiliary contacts adapted to work with low-current signals allow direct connection to PLCs without the need for additional relays.

• Compact Dimensions: Dimensions of 91 x 45 x 107 mm allow easy integration of the contactor into tight installation spaces.

• Digital Documentation: Access to technical documentation via QR code facilitates servicing and troubleshooting.

The rated current AC-1 (400V) is 40A, and the coil voltage is 220 VDC. The contactor has four main normally closed contacts, one auxiliary normally open contact, and one auxiliary normally closed contact, and the connection of the main contacts is realized by means of screw terminals.

The TeSys D LC1DT40MD contactor is a solid and reliable solution for anyone looking for a high-quality device for controlling electrical circuits. Its versatility, durability and ease of installation make it an ideal choice for both professional installers and end users.
