LITTELFUSE AF0025 series arc-flash relay protection solution in our most compact package for OEM applications. The arc-flash relay significantly reduces arc-fault damage in ac and dc compartments by detecting the light from an arc-flash and rapidly providing a trip signal. With a depth of 46.23mm, the compact design can be surface or DIN-rail mounted in the smallest places. This makes it suitable for renewable energy applications such as combiner boxes and inverters, industrial applications including uninterruptible power supplies (UPS) and variable frequency drives (VFDs), as well as junction boxes and panels where space is limited. Product provides fixed light sensitivity, which does not require adjustments during installation. Device delivers internal fail-safe design providing redundant solid-state circuitry.
