⚡ Optical Point & Fiber-Loop Sensors (1.0ms Optical Detect + 40ms Total Clearing)

Arc Flash Optical Point Sensor Calculator

Size optical light point sensors and fiber-optic loop arc detection relays (SEL / ABB / Arcteq) installed in medium/low-voltage switchgear compartments under IEEE 1584: calculate ultra-fast clearing time (1.0 ms optical light flash detection combined with current threshold to trip the main breaker in <40 ms, dropping incident energy below 1.2 cal/cm² Category 0), and safety margins.
