Installation contactor Z-SCH24/25-22 248850

Installation contactor – reliable circuit protection

The Z-SCH24/25-22 contactor is a modular contactor designed for the reliable switching of electrical circuits. Designed by the renowned company Eaton, it combines compact dimensions with high performance, making it an ideal solution for both professional installers and end users. The device is particularly useful in building installations where effective protection against overload and short circuit is required.

Construction and application

This 2-module contactor (width 36mm) operates at a rated voltage of 440V AC and a rated current of 25A. Powered by a control voltage of 20.4-26.4V AC, it is perfect for lighting, heating or ventilation control systems. It has two normally closed and two normally open contacts, providing flexibility in circuit configuration. The mounting depth of 60mm allows for easy installation in electrical distribution boards. This contactor is compliant with the AC-1 utilization category, which means it is designed for switching resistive loads such as heaters or light bulbs.

Key features and benefits

• Contact status indicator: Allows for quick visual control of the device status directly on the housing – facilitates diagnostics and speeds up the location of any problems.
• Large terminals: Provide convenient and safe connection of wires with a cross-section of up to 25mm², which facilitates installation and minimizes the risk of errors.
• Muted operating sounds: Reduce the noise generated during contact switching, improving user comfort.
• High contact pressure force: Guarantees a stable electrical connection and minimizes the risk of electric arc formation, increasing installation safety.
• Made of flame-retardant materials: Provides additional fire safety and resistance to mechanical damage. Additionally, the plastics used are chlorine and halogen-free, which is important from an environmental point of view.
• Compliance with standards: Meets the safety requirements of IP40 standards, which means protection against the ingress of solid objects larger than 1mm – ideal for industrial and domestic environments.
• High switching capacity: The maximum switching capacity for incandescent lamps is as much as 3000W, and for fluorescent lamps (with DUO compensation) – 2552VA, which allows for servicing a wide range of lighting loads.

The Z-SCH24/25-22 contactor is a solid and reliable element of the electrical installation, which will ensure safe and efficient operation of the circuits for a long time. Its compact dimensions and ease of installation make it an ideal choice for both professionals and demanding home users.
