Key Features

• 25A Rated Current: Suitable for low-power circuits that require protection against earth leakage currents.

• 300mA Sensitivity: Designed for fire protection, it detects larger residual currents that may not present an immediate shock risk but could lead to overheating or fire in electrical systems.

• Type AC Detection: Capable of detecting sinusoidal AC leakage currents, making it suitable for typical residential and commercial installations.

• 4-Pole Protection: Provides complete protection for all conductors in three-phase systems, ensuring that all phases and neutral are disconnected in the event of a fault.

• Instantaneous Tripping: The RCCB reacts immediately when the leakage current exceeds the rated threshold, minimizing the risk of damage or fire.

• Test Button: Allows easy testing of the RCCB to verify its operation, ensuring the system remains safe and functional.

• DIN Rail Mounting: Designed for easy integration into electrical distribution panels, saving space and simplifying installation.

• Compliance with IEC Standards: Conforms to IEC 61008-1, ensuring global safety and performance standards.

Applications

The A9R44425 RCCB is intended for use in applications where fire protection is a primary concern due to earth leakage currents, especially in three-phase systems. It is suitable for:

Industrial Installations

• Protects circuits in factories, manufacturing plants, and other industrial facilities that use three-phase electrical systems.

Commercial Buildings

• Provides protection for electrical circuits in offices, shops, and warehouses, where extended leakage currents could present fire risks, especially in older or poorly maintained systems.

Residential Applications (Three-Phase Systems)

• Suitable for large residential complexes or buildings with three-phase power systems, offering protection against potential fire risks due to earth leakage currents.

Electrical Distribution Panels

• Ideal for installation in distribution boards or control panels, offering protection to circuits in larger or more complex electrical installations.
