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.

FAQ
What does the 30 mA rating mean?
It indicates the leakage current level at which the RCCB will trip to protect people from electric shock.
Does this RCCB protect against overload or short circuit?
No, this model provides leakage current protection only and must be used with an MCB for overcurrent protection.
Where is the HNB2L RCCB typically used?
It is used in residential, commercial, and industrial electrical installations where human safety is a priority.
