TeSys D power contactor AC1 25A 4P 1NO 1NC 24VDC coil low consumption LC1DT25BL

TeSys D Power Contactor – Reliable Motor Control

This TeSys D power contactor, with a rated current of 25A, is designed for the reliable control of three-phase motors. Designed for a wide range of industrial and construction applications, it combines durability, compact dimensions, and ease of installation. It is ideal for applications requiring frequent load switching, such as heating, ventilation, air conditioning (HVAC) systems, and various types of machinery and equipment.

Design and Application

The LC1DT25BL contactor is characterized by a solid construction and high quality workmanship. It has 4 normally closed main contacts and 1 normally open and 1 normally closed auxiliary contact, providing flexibility in control circuit configuration. The rated operating power for AC-3 is 5.5 kW at 400V, and the rated current Ie for AC-3 is 12A. The possibility of connecting wires using screw connections ensures a secure and durable electrical connection. Low coil consumption (24VDC) minimizes control energy demand.

Advantages of the TeSys D contactor in points

• Durability and reliability: Designed to operate in harsh industrial conditions, with high mechanical strength – up to 15 million switching cycles.
• Compact dimensions: Width 45 mm, height 85 mm and depth 99 mm allow for mounting in limited space.
• Versatility: Compliance with IEC60335-1 and other world standards (marine, UL) enables use in a variety of applications.
• Safety: Integrated auxiliary contacts (NO+NC) allow direct use of the contactor in safety circuits in accordance with IEC standards.
• Easy identification: Short catalog number with included rated current facilitates the selection of the appropriate model.
• Low power consumption: Low coil consumption (100mA) reduces control energy consumption.
• Digital documentation: Access to technical documentation online via QR code facilitates service and maintenance.
• Compliance with standards: Meets the requirements for electrical household appliances and HVAC in the market thanks to compliance with IEC 60335-1.
