TeSys D power contactor AC3 38A 3P 1NO 1NC 24VDC coil screw terminals LC1D38BD

Power contactor for demanding applications

This 3-pole TeSys D power contactor with a rated current of 38A in AC-3 category is a reliable solution for controlling electric motors. Designed for performance and durability, it performs well in both industrial applications and buildings – heating, ventilation and air conditioning systems. Equipped with a 24V DC coil and 1NO + 1NC auxiliary contacts, it allows for flexible configuration of control and safety circuits.

Design and application

The LC1D38BD contactor is characterized by a compact design with dimensions of 45 x 85 x 101 mm. The use of screw connections ensures secure and durable wire connections. Designed to operate in AC-3 (18.5 kW/400V) and AC-4 (7.5 kW/400V) categories, it perfectly handles motor loads with different characteristics. It can be used in safety applications thanks to the integrated NO+NC auxiliary contacts. Compliance with IEC60335-1 standard guarantees increased resistance to fire and dust, making it an ideal choice for industrial environments and public buildings.

Advantages and benefits

• High mechanical endurance: up to 1.5 million switching cycles – significantly more than competitive solutions (usually 1.0-1.2 million). This translates to a longer service life and less frequent device replacement.
• Built-in auxiliary contacts: It has two auxiliary contacts (1NO + 1NC) in a mirrored standard – this facilitates the direct use of the contactor in safety circuits in accordance with IEC standards.
• Accessory universality: Compatible with a wide range of accessories dedicated to contactors from 9A to 150A – this simplifies component selection and minimizes storage costs.
• Simple selection: The short catalog number contains information about the rated current in the AC-3 category, which makes it easier to identify the appropriate model.
• Digital documentation: Access to complete technical documentation using a QR code – quick access to information needed during installation and service.
• Sustainable development: Labeled with the Green Premium label – a guarantee of compliance with the latest regulations, transparency of environmental impact and products with a closed loop and low CO2 emissions.
• Compliance with standards: Meets applicable industry standards and global standards, including marine and UL certificates.
• Wide application: Ideal for plants and machines, buildings, power supply systems and wastewater management.
