Product Details
The 6A B Curve 30mA A Type 6KA 1P+N RCBO is a compact and reliable electrical protection device designed for modern consumer units and distribution boards. This RCBO, also known as a Residual Current Breaker with Overcurrent protection, combines both earth leakage detection and overcurrent protection in a single module, giving you efficient safeguard against electric shock and circuit overload on a dedicated circuit.
Built to industry standards, this device offers a 6 amp rated current and B curve tripping characteristic that responds quickly to overcurrent without false tripping under normal loads. The Type A residual current detection provides protection against both alternating and pulsating direct current faults, making it suitable for circuits with modern electronics and motorised appliances.
With a 30mA sensitivity, this RCBO reliably detects leakage currents that could indicate a potentially dangerous fault to earth. Its 6kA fault breaking capacity ensures it can deal with significant fault currents safely, protecting both your electrical system and connected appliances.
The 1 Pole + Neutral (1P+N) configuration simplifies installation into standard DIN rail consumer units, helping to save space while maintaining high protection standards. Its compact design is ideal for both residential and light commercial installations where safety, reliability, and space economy are essential.
Whether you are wiring new circuits or upgrading existing ones, the CHINT NB3LEG-B06 RCBO offers dependable performance and peace of mind with combined protection in a single unit.
