TeSys Deca power contactor, AC1, 25A 4P 2NO 2NC 24VAC coil screw terminals LC1D128B7

Power contactor – reliable control of electrical circuits

This four-pole TeSys Deca power contactor (2NO + 2NC) is a robust solution for controlling electrical loads. Designed to operate at 24VAC, it is perfect for a wide range of industrial and construction applications. Its construction based on proven Schneider Electric technologies guarantees long-lasting and trouble-free operation. This contactor is particularly recommended for applications requiring frequent switching and high reliability.

Construction and application

The LC1D128B7 contactor has screw connections, which ensures a secure and durable connection of wires. Built-in auxiliary contacts (1NO + 1NC) increase the functionality of the device, allowing the implementation of additional control circuits. Compact dimensions (85 mm height, 45 mm width and 92 mm depth) allow for easy mounting in limited spaces. Designed for AC-1 circuits with a current of 25A at 400V and AC-3 with a current of 12A at 400V, it will find application in controlling motors, heaters and other electrical devices. It provides effective protection of the circuit against overload and short circuit - like most circuit breakers in this class.

Key features and benefits

• Versatility: Suitable for a wide range of applications, both in industry and construction.
• High reliability: Mechanical endurance of 15 million switching cycles and the ability to operate at a switching frequency of up to 3600 cycles per hour guarantee a long service life of the device.
• Safety: Compliance with IEC, UL, CSA, CCC, EAC and Marine standards ensures safe use in various conditions.
