POCT (Smart Power-Free Shockproof Overcurrent Trip) POCT is like a vaccine for power accidents. It can accurately detect the fault current and trip the circuit breaker within 0.02 seconds (faster than IEEE-39.07 std. 0.025~0.033 seconds), effectively avoiding the expansion of short-circuit accidents. The high-voltage circuit breakers in the world can only trip when there is control/working power supply. But Long Men POCT can work without power POCT completed all functions and seismic verification and certification in 2018, wining glory for Taiwan. So far, it has obtained invention 12 patents in 10 countries (U.S.A, U. K., Germany, France, Russia, India, China, Japan, South Korea, Taiwan) and 10 awards from 6 countries.
