The Littelfuse Arc-Flash Relay protects electrical systems by detecting arc flash incidents fast. This relay should be used whenever working on energized equipment throughout general industrial facilities, and is both easy to install and loaded with features and capabilities. The Arc-Flash Relay can use up to 24 light sensors, including optional fiber-optic cable sensors to protect difficult-to-reach compartments. It reliably detects developing Arc-Flash incidents in less than one millisecond by looking for a combination of excess light and current and offers programmable definite-time overcurrent protection and adjustable light trip-level to minimize nuisance tripping.
