LH300 Integrated Protection Device of Arc Light

LH300 integrated protection device of arc Light is specially designed according to the bus protection characteristics of medium and low voltage systems. The main control unit of the system takes the 32-bit high-end DSP chip as the core. In the aspect of failure current recognition,we adopt the special algorithm to maximize personnel safety and reduce equipment damage caused by arc light fault.

The actuation time of LH300 is faster than the conventional protection devices, which reduce the harm as much as possible. It is the optimal scheme for quickly handling accidents and restoring power supply.
