Kanlux KRD10-4/25/30-A Residual Current Circuit Breaker 4P 25A 30mA Type AC

The Kanlux KRD10-4/25/30-A is a high-quality 4-pole residual current circuit breaker engineered to enhance electrical safety in various environments. This device is designed to monitor electrical circuits and detect leakage currents, automatically disconnecting the power supply when a fault is identified to prevent potential hazards. With its robust construction and reliable performance, it serves as a critical component for protecting both users and electrical equipment from the dangers of ground faults.

The primary advantage of this residual current circuit breaker lies in its ability to provide rapid and precise protection against electrical leakage. By maintaining a consistent 30mA sensitivity threshold, it ensures that the circuit is interrupted immediately upon detecting an imbalance, thereby minimizing the risk of electric shock. Its 4-pole configuration allows for versatile installation in three-phase electrical systems, offering broad compatibility and dependable operation in demanding residential and commercial settings.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Protection of lighting and socket circuits
• General electrical safety upgrades

When it may not be suitable

This device is designed for AC type leakage detection and may not be suitable for circuits containing electronic equipment that produces DC components or high-frequency interference, as these may interfere with the tripping mechanism. It is also not intended for use in environments where the rated current exceeds 25A.

Key specifications

• Number of poles: 4
• Rated current: 25A
• Rated residual operating current: 30mA
• Type: AC

How to use

The installation of the Kanlux KRD10-4/25/30-A must be performed by a qualified electrician in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within a distribution board. Ensure that all wiring connections are tightened securely to prevent overheating. After installation, it is recommended to use the integrated test button to verify that the mechanism functions correctly and triggers the disconnection as expected.

What to consider before purchase

• Verify that the 25A rated current is sufficient for your specific circuit load.
• Ensure the 4-pole configuration matches your electrical system requirements.
• Confirm that the AC type protection meets the safety standards required for your connected appliances.

Usage recommendations: Regularly test the residual current circuit breaker using the built-in test button at least every six months to ensure the mechanical parts remain operational and the device continues to provide effective protection.
