Product Details
Product Details
The NB310L-2P-B16 is a high-performance 2-pole RCBO engineered to streamline your installations by replacing the need for separate MCBs and RCDs.
With a 16A rating and a B curve characteristic, it provides effective overload and short-circuit protection while remaining stable during moderate inrush currents. For modern environments filled with electronic devices, the Type A residual current detection is essential, as it senses both standard AC and pulsating DC leakage.
This unit is designed for maximum efficiency, occupying just two modules of width on a standard 35mm DIN rail. It offers a 6kA breaking capacity and 30mA residual current sensitivity, ensuring it meets the rigorous safety requirements of residential, commercial, and light industrial applications. Whether you are upgrading an existing consumer unit or building a new distribution board from scratch, this RCBO offers a professional-grade solution that ensures site safety and reduces the risk of electrical fire or shock.
