FAQs

 

What is the main function of the NXBL-40Y RCBO?

It combines residual current protection and over-current protection, ensuring comprehensive electrical safety by disconnecting the circuit during earth leakage, overload, or short-circuit faults.

 

What types of electrical systems is it suitable for?

The NXBL-40Y is ideal for residential, commercial, and industrial TN and IT systems, protecting both people and equipment from electrical faults.

 

What’s the difference between the B and C tripping curves?

B curve (3–5 In): Protects circuits with low inrush currents and long cables.

C curve (5–10 In): Suited for circuits with resistive and inductive loads, such as motors and lighting.

 

What sensitivity options are available?

It offers 30mA, 100mA, and 300mA sensitivities—covering personal protection, equipment safety, and fire prevention.

 

How is the NXBL-40Y installed?

It mounts on a 35mm DIN rail (EN 60715) with quick-release clips, supporting top and bottom connections for convenient installation in compact panels.
