TeSys D power contactor AC3 18A 4P 1NO 1NC 24VDC coil LC1D18BD

TeSys D power contactor – reliable motor control

This 4-pole TeSys D power contactor with a rated current of 18A in AC-3 category is a robust solution for controlling motors in demanding industrial and building applications. Designed for durability and efficiency, LC1D18BD provides reliable switching of electrical circuits. Equipped with a 24V DC coil, this contactor is ideal for systems powered by direct current, and the presence of one normally open (1NO) and one normally closed (1NC) auxiliary contact expands its functionality, enabling integration with various control and safety circuits.

The LC1D18BD contactor stands out from the competition in terms of mechanical endurance – it offers as many as 1.5 million switching cycles, which translates to a longer service life and less frequent replacement. Additionally, the built-in two auxiliary contacts (NO+NC) in a mirrored standard facilitate the implementation of safety-related solutions, meeting the requirements of the IEC standard. Importantly, TeSys D contactors use the same accessories for the range from 9A to 150A, simplifying component selection and minimizing storage costs.

Construction and application

The LC1D18BD contactor has been designed for easy installation and a wide range of applications. Compact dimensions (77 mm height, 95 mm depth and 45 mm width) allow for mounting in limited space. Screw connection of the main contacts ensures secure and durable electrical connections. The device is compliant with IEC60335-1, which confirms its increased resistance to fire and dust – a feature particularly important in home installations, heating, ventilation and air conditioning systems, and industrial environments. Available technical documentation in the form of a QR code facilitates access to detailed product information.
