By using an optical sensor for arc detection and static output, arc protection operates instantaneously in less than 1ms, which is negligible in comparison with disconnection time of a circuit breaker.That feature enables early arc recognition, and greatly decreases possible damages.<\/p><p>Arc protection system gives high contribution in protection of personnel and equipment with low price and simple application.
