TeSys D power contactor AC3 38A 3P 1NO 1NC 24VDC coil low consumption LC1D38BL

TeSys D power contactors – reliability and efficiency in motor control

This three-pole TeSys D power contactor is designed for reliable control of motors up to 18.5 kW at 400V (AC-3). The rated operating current of 38A ensures a wide range of applications in various industrial and building installations. The contactor design is based on solid screw connections, guaranteeing secure and durable electrical connections.

This contactor is distinguished by its low coil power consumption of 24V DC, which translates into energy savings and reduced power supply load. Built-in auxiliary contacts – one normally open (1NO) and one normally closed (1NC) – with a mirrored NC certificate, facilitate integration with control and safety circuits. This allows for direct connection to PLCs, using signals with a minimum current of 1 mA.

Application and design features

The TeSys D contactor is characterized by high mechanical endurance – up to 15 million switching cycles and the ability to operate at a frequency of up to 3600 cycles per hour. Compact dimensions (45 mm wide, 85 mm high and 101 mm deep) allow for easy mounting on DIN rails or with screws. Compliance with IEC, UL, CSA, CCC, EAC and Marine standards confirms its versatility and possibility of use in various environmental conditions.

Additionally, the product meets the requirements of IEC 60335-1 standard, which means increased resistance to fire and dust – important in domestic applications, heating, ventilation and air conditioning (HVAC) systems. Digital technical documentation in the form of a QR code facilitates the selection and installation of the device. TeSys Deca contactors are also compliant with the Green Premium label, which guarantees compliance with environmental protection regulations (RoHS/REACh) and transparency regarding environmental impact.
