FAQs

 

What makes the NB2LE-80ZT RCBO different from conventional circuit breakers?

It combines residual current detection, overcurrent protection, and intelligent control functions in one device, with smart features like remote operation, RS485/Bluetooth connectivity, and self-testing for enhanced reliability.

 

How does the communication system work?

The RCBO supports Modbus-RTU via RS485 for industrial integration and Bluetooth BLE 5.0 for mobile or gateway-based monitoring, making it suitable for smart energy management systems.

 

Can this device replace traditional breakers in existing panels?

Yes. The NB2LE-80ZT is DIN-rail mountable (TH35) and has the same form factor as standard RCBOs, allowing direct replacement while adding smart capabilities.

 

What environmental conditions can it operate under?

It operates reliably between –25 °C and +70 °C, making it suitable for a wide range of residential, commercial, and industrial environments.

 

What types of leakage currents can it detect?

Type AC: Detects sinusoidal AC residual currents.

Type A: Detects both AC and pulsating DC leakage currents from electronic loads.
