TeSys Deca power contactor, AC1, 25A 4P 2NO 2NC 48VAC coil screw terminals LC1D128E7

Power contactors – reliable control of electrical circuits

This TeSys Deca four-pole power contactor, designed for operation with AC1 loads, is a solid solution for both professional installers and end users. A rated current of 25A at 400V provides effective control of motors and other electrical devices. The construction with two normally open (2NO) and two normally closed (2NC) main contacts, as well as additional auxiliary contacts (1NO and 1NC), provides great flexibility in circuit configuration.

This contactor is distinguished by its versatility – it will work perfectly in industrial plants, commercial buildings, power systems, as well as in water and sewage management or mining. Its compact dimensions (45 mm wide, 85 mm high and 92 mm deep) allow for easy mounting in tight spaces. Connection via screw terminals guarantees secure and durable electrical connections.

Design and characteristic features

The TeSys Deca contactor has been designed with reliability and durability in mind. It has built-in auxiliary contacts in a mirror configuration (NO+NC), which allows for direct use in safety circuits in accordance with IEC standards. Additionally, the auxiliary contacts are adapted to signals with a minimum current of 1 mA, allowing them to be connected to PLC controllers without the need for additional relays.

The AC coil with a voltage of 48V (50/60Hz) ensures compatibility with most standard control systems. Mechanical endurance of 15 million switching cycles and the ability to operate at a frequency of up to 3600 cycles per hour guarantee long-term and trouble-free operation even in demanding industrial conditions.

Compliance with standards and safety

This contactor meets a number of international standards (IEC, UL, CSA, CCC, EA C, Marine), which confirms its high quality and safety of use. The product also has a Green Premium certificate, which means compliance with environmental protection regulations (RoHS/REACh) and transparency in disclosing information about environmental impact. The use of high-quality materials and a solid construction ensure resistance to dust and harsh working conditions, as well as increased resistance to fire according to IEC60335-1.
