Patented magnetic technology provides clear confirmation of proper blade depth and rotation, helping operators verify a full disconnect switch closure from the ground.
Verifying proper blade depth and rotation of a high-voltage disconnect switch has long challenged ground-level operators. Southern States MACI® uses magnetic actuation to deliver highly visible, foolproof confirmation of a proper switch closure. This assurance helps minimize costly unplanned outages and strengthens operator confidence in the field. MACI®’s reflective “closed” pattern can be seen from up to 100 feet away and remains visible and functional even in icy conditions.
