Motor Protection Products
The 100 M series cater for protection against overloading of motors (sustained and cyclic overloading conditions), phase loss and unbalanced load conditions as well as short circuit protection with user selectable short circuit detection thresholds. The MA range of relays with its associated parts will permit up to 8 different preset parameters to be altered to meet specific motor specification setting parameters by means of a couple of key strokes and can provide LED fault indications for all fault conditions both on the relay face and remotely by means of an optional extra RDU.
