These medium-voltage indicators flash with enough illumination to allow safe viewing from outside the enclosure through an access window (IR window) on a medium-voltage starter, transformer, switchgear, and other power distribution equipment. Permanently installed into an electrical system, the indicators do not require batteries or maintenance because they receive power from the line voltage. The product also features a blown-fuse indicator.
