AF0500弧闪继电器
AF0500为基于微处理器的弧闪保护继电器，可通过检测弧闪发出的亮光并快速跳闸来限制电弧故障造成的损害。
PGR-8800弧闪继电器
PGR-8800是通过UL和cUL认证的弧闪继电器，它能够通过搜寻超常光电量组合，可靠地检测出潜在发生的弧闪事故，并且不会导致误脱扣。
NEC 240.67 Arc-Energy Reduction
Arc energy reduction is critical for electrical safety in the workplace. NEC 2011 introduced an Arc Energy Reduction requirement for circuit breakers (NEC 240.87) rated 1200 A and higher. The added circuit breaker requirement has reduced arc-flash injuries since being introduced by lowering fault clearing times. The value of 0.07 s for the new fuse clearing time requirement was chosen to align with circuit breakers using zone selective interlocking.
