Kanlux KRO6-2/B6/30 Residual Current Circuit Breaker with Overcurrent Protection 2P B 6A 0.03A Type AC

The Kanlux KRO6-2/B6/30 is a high-quality 2-pole residual current circuit breaker with overcurrent protection, commonly known as an RCBO. This device is engineered to provide comprehensive protection for electrical circuits by combining the functions of a miniature circuit breaker and a residual current device in a single compact unit. It is designed to detect and interrupt electrical circuits in the event of overloads, short circuits, or leakage currents, thereby enhancing the safety of residential and commercial electrical installations.

Advantages

The primary benefit of this device is its dual-functionality, which saves significant space in electrical distribution boards by integrating two protective components into one housing. The B-curve characteristic ensures reliable operation for standard domestic and light commercial applications, while the 30mA sensitivity is specifically calibrated to protect individuals against the risk of electric shock. Its robust construction ensures long-term reliability and consistent performance under standard operating conditions, making it an essential component for modern electrical safety systems.

Suitable for

• Residential electrical distribution boards
• Light commercial and office electrical circuits
• Protection of lighting and general-purpose socket outlets
• Single-phase electrical installations requiring combined overload and leakage protection

When it may not be suitable

This device is not intended for use in DC electrical systems or circuits where high-frequency interference is present, as it is classified as Type AC. It is also not suitable for industrial environments requiring higher breaking capacities or specific protection curves beyond the standard B-curve.

Key specifications

• Number of poles: 2
• Rated current: 6A
• Residual current sensitivity: 30mA
• Tripping characteristic: B-curve
• Device type: AC

How to use

The device must be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting on a standard DIN rail within a distribution enclosure. Ensure that the supply cables are securely connected to the input terminals and that the load circuits are connected to the output terminals, observing the correct polarity and torque specifications provided by the manufacturer.

What to consider before purchase

• Verify that the 6A rated current is appropriate for the specific load of your circuit
• Ensure the installation environment is compatible with Type AC residual current devices
• Check that the available space in your distribution board is sufficient for a 2-pole module

Usage recommendations

Regularly test the functionality of the device using the integrated test button to ensure the mechanical tripping mechanism remains operational over time. It is recommended to perform this test at least every six months.
