TeSys D power contactor AC3 9A 3P 1NO 1NC 24VAC coil screw terminals LC1D09B7

TeSys D power contactor – reliable motor control

This 3-pole TeSys D contactor from Schneider Electric is a robust solution for controlling motors in a wide range of industrial and HVAC applications. Designed for easy installation and operation, LC1D09B7 provides reliable circuit switching with a rated current of 9A in AC-3 category and a power of 4kW at 400V. Equipped with a 24VAC coil, it is ideal for systems powered by mains voltage.

Design and application

The LC1D09B7 contactor features screw connection of the main contacts, which facilitates assembly and ensures a secure connection of the wires. It has one normally open (1NO) and one normally closed (1NC) auxiliary contact, enabling integration with various control and safety circuits. It can be used in safety applications thanks to the standard arrangement of NO+NC auxiliary contacts. It is compatible with IEC 60335-1 standard, which confirms its resistance to fire and dust, as well as compliance with the requirements of domestic installations, heating, ventilation and air conditioning systems.

Advantages and benefits for installers and users

• High mechanical durability: The contactor offers up to 15 million switching cycles, which translates to a long service life and minimizes the need for replacement.
• Integrated auxiliary contacts: Standardly equipped with a mirror set of auxiliary contacts (NO+NC) facilitates the implementation of safety circuits in accordance with IEC standard.
• Versatility: The same additional accessories fit TeSys D contactors with different current ranges (from 9A to 150A), simplifying storage and component selection.
• Easy identification: The short catalog number contains information about the AC-3 rated current, which facilitates quick selection of the appropriate model.
• Digital documentation: Access to complete technical documentation via QR code allows for quick troubleshooting and installation optimization.
• Compliance with standards: Meets applicable industry standards and global standards, including marine and UL certifications.
