TeSys D power contactor AC3 12A 3P 1NO 1NC 24VAC coil LC1D12B7

TeSys D power contactor – reliable motor control

This 3-pole TeSys D power contactor from Schneider Electric is a robust solution for controlling motors in a wide range of industrial and construction applications. Designed for reliability and durability, LC1D12B7 provides efficient circuit switching and safe operation of devices. A rated current of 12A in AC-3 category at 400V allows operation of motors up to 5.5 kW.

This contactor is characterized by its versatility and ease of integration with existing installations. It has screw connection of the main contacts, which facilitates mounting and connection of wires. Additionally, it is equipped with one normally open auxiliary contact (1NO) and one normally closed (1NC), which allows for the implementation of various control and signaling functions. A coil powered by 24VAC (50/60Hz) ensures compatibility with most standard control systems.

Construction and user features

TeSys Deca contactors are distinguished by a modern design and high quality of workmanship. Compliance with IEC 60335-1 standard guarantees increased resistance to fire and dust, making them an ideal choice for demanding work environments. Compact dimensions (77 mm height, 45 mm width and 86 mm depth) allow for easy installation even in tight spaces.

It is worth noting a few key advantages of this model:

• Durability: TeSys D contactors are characterized by extremely high mechanical durability – up to 15 million switching cycles at a frequency of 3600 cycles/hour, which translates to a long service life of the device.
• Safety: Integrated auxiliary contacts in a standard mirror arrangement (NO+NC) allow direct use of the contactor in safety circuits in accordance with IEC standards, and their adaptation to signals with a minimum current of 1 mA allows direct connection to PLCs.
• Versatility: A wide range of accessories available for TeSys D contactors allows you to adapt the device to the most demanding applications.
• Simple selection: A short catalog number containing the rated current in AC-3 category facilitates identification and selection of the appropriate model.
• Digital documentation: Easy access to technical documentation online using the QR code on the device housing.

This contactor not only meets applicable industrial standards and global standards (including marine and UL certificates), but is also compliant with the requirements for electrical appliances for household use and HVAC systems, making it a versatile solution for various industries – from industrial plants to residential buildings and wastewater management. Choosing the TeSys D power contactor is an investment in a reliable and durable solution that will ensure safe and efficient motor control for years to come.
