FAQs

 

What is the NB2LE-40ZT used for?

It’s a smart RCBO that combines residual current protection and over-current protection with real-time monitoring and remote control for modern electrical systems.

 

How is the NB2LE-40ZT different from traditional RCBOs?

Unlike standard RCBOs, it supports RS485 and Bluetooth communication, fault self-diagnosis, and remote operation via CHINT’s SMG-WL1SR Smart Gateway.

 

What protection functions are built into this device?

It offers comprehensive protection — overload, short-circuit, over/undervoltage, leakage, and phase loss — ensuring maximum safety for connected circuits.

 

What kind of electrical data can it measure?

The breaker can measure voltage, current, and power with high accuracy (±1% for voltage/current, ±2% for power), enabling effective energy management.

 

Can it be remotely managed and monitored?

Yes. It communicates via RS485 (Modbus-RTU) and integrates seamlessly with smart energy management systems, allowing remote operation and fault alarm functions.
