LSiS RKN2P Residual Current Circuit Breaker 2P 40A 30mA Type A

The LSiS RKN2P is a high-quality 2-pole residual current circuit breaker engineered to provide essential electrical safety in both residential and commercial environments. This device is designed to monitor electrical circuits for leakage currents, automatically disconnecting the power supply when a fault is detected to prevent electric shock and potential fire hazards. With a robust construction and reliable internal mechanism, it serves as a critical component in modern electrical distribution systems.

Advantages

The primary advantage of the LSiS RKN2P is its Type A classification, which allows it to detect not only standard alternating current residual currents but also pulsating direct current components. This makes it a versatile solution for protecting modern electronic equipment that may produce non-sinusoidal leakage currents. Its compact 2-pole design ensures easy integration into standard distribution boards, while the 40A rated current and 30mA sensitivity provide a balanced level of protection suitable for most household and light commercial applications.

Suitable for

• Residential electrical distribution boards
• Protection of lighting and power socket circuits
• Commercial office installations
• Equipment with electronic components that generate pulsating DC leakage

When it may not be suitable

This device is not intended for use in high-current industrial applications exceeding its 40A rating. It is also not suitable for protecting circuits that require a different sensitivity level, such as specialized medical equipment or high-leakage industrial machinery.

Key specifications

• Number of poles: 2
• Rated current: 40A
• Residual current sensitivity: 30mA
• Type: A

How to use

The LSiS RKN2P must be installed by a qualified electrician in accordance with local electrical regulations. It is typically mounted on a standard DIN rail within a distribution enclosure. Ensure that the input and output wires are securely connected to the designated terminals, observing the correct polarity and torque settings. Once installed, the device should be tested using the integrated test button to verify that the tripping mechanism functions correctly.

What to consider before purchase

• Verify that the 40A rated current matches your circuit load requirements.
• Ensure the 30mA sensitivity is appropriate for the intended level of human protection.
• Confirm that your installation requires Type A protection for specific electronic loads.
• Check the available space in your distribution board for a 2-pole device.

Usage recommendations

Regularly test the residual current circuit breaker using the test button at least every six months to ensure the mechanical tripping function remains operational.
