NTAA81 series air circuit breaker is suitable for AC 50/60Hz, rated working voltage 415V/690V power supply and distribution network, used to distribute electric energy and protect lines and power equipment from overload, under voltage, short circuit, grounding and other faults. The circuit breaker adopts precise selective protection and multi-function intelligent controller with complete protection and communication functions.

In order to improve the reliability of power supply and avoid unnecessary power outages, an advanced intelligent controller with a communication interface can be selected, which can be connected through the field bus to realize the four remote functions of telemetry, remote adjustment, remote control and remote signaling to meet the needs of the intelligent power distribution network.
