Our French Series Adjustable RCBO (LRPG Series) is a high-performance residual current circuit breaker with integrated protection, engineered exclusively for residential and light civil electrical safety. This 1P+N leakage protection circuit breaker delivers triple protection against leakage, overload, and short circuit faults, compatible with AC 50/60Hz systems and rated voltage 230V/240V, for installations with rated current up to 60A. Also widely known as disjoncteur différentiel in French-speaking markets, it is designed for professional electrical project contractors, residential real estate developers, and power distribution equipment integrators. This adjustable residual current breaker serves as a core safety component for modern building electrical systems, supporting infrequent line switching under normal working conditions.
This residual current protection circuit breaker integrates three critical protection functions in one compact unit: reliable earth leakage protection, precise overload protection, and instant short circuit protection. It eliminates the need for separate protective devices, reducing installation complexity and potential failure points for large-scale residential projects.
With multiple rated current ranges (5A to 60A) and selectable earth leakage sensitivity levels, our 1P+N RCBO adapts to diverse residential project requirements, from single apartment units to multi-family housing complexes. The adjustable design allows on-site tuning to meet local electrical codes and project-specific safety standards.
Engineered with a space-saving footprint, this residential RCBO fits seamlessly into standard energy meter boxes and distribution panels, ideal for high-volume residential construction projects. Its cost-optimized design delivers reliable performance without compromising safety, making it the preferred choice for conventional utility service connection projects.

This leakage protection switch is tailored for professional project partners in residential construction, utility infrastructure, and building electrical retrofitting. Core application scenarios include:
Utility service connection interfaces between power grids and end-user residential installations
Integrated installation in household and multi-occupancy energy meter boxes
Incoming main switch for single-family and multi-family residential buildings
Outgoing line side protection for power grid distribution transformers
Lighting and power distribution protection for small office buildings and similar civil structures
Electrical safety retrofitting projects for existing residential properties
Pre-Installation Check: Verify the breaker’s rated voltage, current, and leakage sensitivity match the project’s electrical system design; inspect the device for transportation damage.
Mounting Installation: Secure the breaker on a standard 35mm DIN rail in the distribution panel, ensuring firm fixation and proper wiring clearance.
Wiring & Adjustment: Connect phase and neutral lines strictly following terminal markings; select the appropriate rated current and leakage sensitivity based on load requirements.
Post-Installation Test: After wiring, close the breaker and press the test button to verify normal leakage protection function before grid connection.
This residential electrical safety RCBO is designed for AC 50/60Hz 230V/240V systems, perfectly matching standard single-phase residential power networks worldwide.
Yes. It is engineered to serve as the main incoming switch for residential building entry, providing full-line protection against leakage, overload, and short circuit faults.
We offer three standard leakage operating current levels: 100mA, 300mA, 500mA, with corresponding non-operating currents of 50mA, 150mA, 250mA, to meet diverse regional safety codes.
