Product Overview
The HNB2L Residual Current Circuit Breaker (RCCB) is designed to enhance electrical safety by detecting leakage currents that may pose a risk of electric shock or fire. When the residual current reaches 30 mA, the device instantly disconnects the power supply, preventing harm to people and protecting electrical systems.
This model provides leakage current protection only and does not include overcurrent or short-circuit protection. It is commonly installed in combination with MCBs or other protective devices to form a complete low-voltage protection system.
Key Features
Residual Current Protection (30 mA): Protects against electric shock and leakage faults
High Breaking Capacity: Rated short-circuit capacity up to 6kA
Automatic Circuit Disconnection: Rapid response when leakage current is detected
No Overcurrent Protection: Designed to work alongside MCBs for full protection
Wide Application Range: Suitable for homes, offices, commercial buildings, and industrial installations
Reliable Performance: Enhances safety for both people and electrical assets
Typical Applications
Residential electrical distribution systems
Office buildings and commercial facilities
Industrial electrical installations
Circuits requiring protection against electric shock
Electrical systems combined with MCBs for full protection
Power distribution panels focused on human safety
