## Summary description

The LSiS RKN-4P-40A/30mA is a 4-pole residual current circuit breaker (RCCB) designed for electrical safety. It features a 40A rated current and 30mA sensitivity, operating on Type AC characteristics. This device provides essential protection against leakage currents in residential and commercial electrical installations, ensuring reliable circuit disconnection during faults to prevent electrical hazards.

## Long description

The LSiS RKN-4P-40A/30mA is a high-quality 4-pole residual current circuit breaker (RCCB) 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. By providing a reliable barrier against electrical hazards, it serves as a critical component for protecting both personnel and electrical infrastructure in residential and commercial settings.
Advantages
This residual current circuit breaker offers robust protection by reacting quickly to residual currents, which helps prevent electric shocks and potential fire hazards caused by insulation failures. Its 4-pole configuration allows for versatile application in three-phase electrical systems, ensuring comprehensive monitoring across all phases and the neutral wire. The device is built with high-quality materials to ensure long-term operational stability and consistent performance under standard electrical loads.
Suitable for
Residential electrical distribution boards
Commercial office building power systems
Protection of lighting and socket circuits
General electrical safety in industrial facilities
This device is not suitable for DC-sensitive applications, as it is specifically designed for Type AC leakage current detection. It should not be used as a primary overload or short-circuit protection device, as it does not contain an integrated miniature circuit breaker (MCB) mechanism.
Key specifications
Number of poles: 4
Rated current: 40A
Rated residual operating current: 30mA
Type: AC
The device 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 board. Ensure that the supply cables are correctly connected to the input terminals and that the load is properly wired to the output terminals. After installation, the test button should be pressed to verify the mechanical operation and the tripping function of the breaker.
What to consider before purchase
Verify that the 40A rated current matches the requirements of your electrical circuit
Ensure the 30mA sensitivity is appropriate for the intended level of protection
Confirm that the installation environment is compatible with Type AC residual current devices
Check the available space on the DIN rail within your distribution enclosure
Usage recommendations: It is recommended to perform a manual test using the integrated test button at least once every six months to ensure the device remains in good working order and that the tripping mechanism is not seized.
