FAQs

 

What is the main function of the NB2LE RCBO?

It integrates overload, short-circuit, and residual current protection in one unit. When leakage or electric shock occurs, it disconnects the circuit instantly to prevent harm to people and damage to equipment. 

 

What configurations and tripping types are available?

NB2LE is available in 1P+N configuration, with Type B and Type C tripping curves to suit different load conditions. Type B suits resistive loads; Type C handles inductive loads such as motors. 

 

What leakage current ratings can be selected?

You can choose rated residual currents of 30 mA, 100 mA, or 300 mA to match protection needs — from personal safety to fire prevention and system protection. 

 

Can the NB2LE be mounted on standard DIN rails?

Yes. The RCBO is designed for quick DIN rail (TH35-7.5) installation, making it compatible with modern electrical panels. 

 

What types of circuits is this RCBO suitable for?

It supports AC 230/240 V, 50/60 Hz systems and is ideal for residential, commercial, and industrial circuits where personnel and equipment protection are critical.
