Contactor D 3P AC3-25A, NZ+NO, 42V 50/60Hz LC1D25D7

TeSys Deca Contactors – Reliability and Compactness in Motor Control

This 3-pole contactor from the TeSys D series is a robust solution for controlling motors with a rated current of up to 25A in AC-3 circuits. Designed for performance and durability, it is perfect for both industrial and commercial applications. Equipped with a 42V AC (50/60Hz) coil and built-in 1NO+1NC auxiliary contacts, it provides flexibility and reliability in control circuits.

Construction and Mounting

The contactor features a compact design (dimensions 85 x 45 x 92 mm) and can be mounted on a DIN rail or with screws. Screw connection of the main contacts guarantees secure and safe wire connections. The built-in auxiliary contacts, configured in a mirrored arrangement (normally open and normally closed), facilitate integration with various control systems and provide additional safety features. Designed to operate at speeds of up to 3600 cycles per hour, it withstands intensive use without loss of performance.

Application and Compliance with Standards

The LC1D25D7 contactor complies with many standards (IEC, UL, CSA, CCC, EAC, Marine), confirming its versatility and usability in various environments. It meets the requirements of IEC 60335-1, making it suitable for applications in residential buildings, heating, ventilation and air conditioning (HVAC) systems. Additionally, it has a Green Premium certificate, which means compliance with environmental protection regulations (RoHS/REACh) and transparency regarding environmental impact. It can be used in industries such as: industrial plants, construction, water and wastewater management, and mining.

Performance and Operating Parameters

This contactor allows for effective control of motors with a rated power of up to 11 kW at 400V AC (AC-3) and 5.5 kW at 400V AC (AC-4). The rated operating current is 25A for AC-3 and 12A for AC-4 at 400V. It provides reliable operation even under heavy loads and frequent switching cycles – it withstands as many as 15 million mechanical cycles. The operating voltage is 440…440 V for both 50Hz and 60Hz frequencies.
