Manufacturer: Horstmann
Description: When a short -circuit occurs, a mixer is lifted by the magnetic field and stirs up red particles in a clear fluid. The red particles remain suspended for 6 to 8 hours in the fluid and indicate the short-circuit. When this time has elapsed, they sink by gravity, leaving the solution colourless (automatic reset).
This indicator can however be installed or removed by a hot stick.
