Kanlux KRD10-4/100/30-AC Residual Current Circuit Breaker 4P 100A 30mA Type AC

The Kanlux KRD10-4/100/30-AC is a high-performance 4-pole residual current circuit breaker engineered to enhance electrical safety in various environments. This device is designed to monitor electrical circuits for leakage currents, providing rapid disconnection when a fault is detected. By maintaining a rated current of 100A and a sensitivity threshold of 30mA, it effectively mitigates the risk of electric shock, making it a critical component for modern electrical distribution boards in both residential and commercial settings.

Advantages

This residual current circuit breaker offers robust protection by continuously monitoring the balance of current in the circuit. Its 4-pole configuration allows for versatile application in three-phase systems, ensuring comprehensive coverage across all phases and the neutral wire. The device is built to high manufacturing standards, providing reliable operation and long-term durability. Its sensitivity of 30mA is specifically calibrated to provide human protection against accidental contact with live parts, while the 100A capacity supports demanding electrical loads without compromising safety.

Suitable for

• Residential electrical distribution boards
• Commercial building electrical systems
• Protection of three-phase electrical circuits
• General purpose leakage current monitoring

This device is not suitable for DC-sensitive applications, as it is specifically designed for AC type leakage currents. It should not be used in environments where high-frequency interference or specific industrial power electronics might cause nuisance tripping, as it is optimized for standard AC electrical installations.

Key specifications

• Number of poles: 4
• Rated current: 100A
• Rated residual operating current: 30mA
• Type: AC

Installation must be performed by a qualified electrician in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within an enclosure. Ensure that the supply voltage matches the device specifications before connection. Once installed, the test button should be pressed periodically to verify the mechanical functionality of the tripping mechanism.

What to consider before purchase

• Verify that your electrical system requires a 4-pole configuration
• Ensure the 100A rated current is sufficient for your total circuit load
• Confirm that the AC type is appropriate for your specific equipment
• Check available space in your distribution board for a 4-module wide device

Regular testing of the residual current circuit breaker using the integrated test button is recommended at least every six months to ensure the device remains in optimal working condition.
