Contactor D 3P AC3-38A, NZ+NO, 48V DC LC1D38ED

Three-pole contactor – reliable motor control

This TeSys Deca contactor, with a rated current of 38A, is designed for efficient control of three-phase motors. Equipped with three normally open (3NO) main contacts and built-in auxiliary contacts (1NO+1NC), it provides versatility and reliability in a variety of applications. The use of a 48V DC powered coil with a surge suppression module guarantees stable operation and protection against interference.

Design and application

The LC1D38ED contactor is characterized by a compact design (dimensions: 85 mm x 45 mm x 101 mm) and the possibility of mounting on a DIN rail or with screws. It is intended for AC-3 circuits with a rated power of up to 18.5 kW at 400V and AC-4 with a power of 7.5 kW at 400V. It can also be used in AC-1 circuits with a rated current of up to 50A. Thanks to its high mechanical endurance (15 million switching cycles) and switching frequency (up to 3600 cycles per hour), this contactor performs well in demanding industrial conditions.

Advantages and benefits

• Versatility: Possibility of use in various applications thanks to high rated parameters and contact configuration.
• Reliability: Built-in surge suppression module and high mechanical endurance ensure long-lasting and trouble-free operation.
• Safety: Integrated auxiliary contacts in a mirror configuration (NO+NC) allow for the construction of safe control circuits, compliant with IEC standards.
• Easy installation: Compact dimensions and the possibility of mounting on a DIN rail facilitate installation and integration with existing systems.
• Compliance with standards: Meets the requirements of many standards (IEC, UL, CSA, CCC, EAC, Marine) and the Green Premium standard (RoHS/REACh), which confirms its high quality and care for the environment.
• Wide range of applications: ideal for use in industrial plants, buildings, power supply systems or water and wastewater management.
• Simple selection: The short catalog number contains information about the rated current in the AC-3 category, which makes it easier to choose the right model.
• Digital documentation: Available technical documentation online after scanning the QR code facilitates servicing and troubleshooting.

In addition, this contactor is compatible with a wide range of accessories, such as auxiliary contact blocks and surge suppressors, allowing it to be adapted to specific application needs. The main contacts made of silver alloy ensure good electrical conductivity and long device life.
