The RP-Onesto RCCB is a two-pole Type A residual current device rated at 40A with a 30mA fault-current trip threshold. It detects ground-fault currents caused by direct or indirect contact with conductive parts and disconnects the circuit before they reach dangerous levels.

The 6kA short-circuit capacity withstands typical domestic and small-commercial fault levels, while the AC 230V / 50Hz electromechanical operation suits standard mains installations. The 35mm DIN rail format integrates with conventional consumer units and distribution boards.

Key Features

• Two-pole Type A construction — detects AC and pulsating DC residual currents
• 40A rated current handles the load of most domestic sub-circuits
• 30mA rated fault current for personal protection against electric shock
• 6kA short-circuit breaking capacity
• Standard 35mm DIN rail mounting for easy panel integration

Product Benefits

• Type A sensitivity protects against modern loads that draw pulsating DC residual currents
• 30mA trip threshold meets the personal-protection level required for habitable areas
• Electromechanical trip mechanism operates without auxiliary supply
• IP20 indoor rating suits installation inside a closed consumer unit or panel
• 50Hz rated frequency matches European mains supply
