Transient/Surge Absorbers (T/SA’s) provide system designers with a low cost, effective method of protecting sensitive electrical and electronic equipment from damage caused by switching transients, coil and motor backlash and near miss lightning strikes. There are 3 types available; single phase (1P), 3-phase DELTA 3- wire (3PD), and 3-phase WYE 4-wire (3PY). Each of these types are available in AC voltages of 120, 208, 240 and 480VAC.
T/SA’s are designed using a ceramic and metal oxide technique which causes the resistance of the device to decrease abruptly if the rated voltage is exceeded. Voltage ranges are achieved by varying the types of oxide used in each model. Resistance changes are very fast, requiring less than 50 nanoseconds after the threshold voltage is exceeded. All models can repeatedly absorb in excess of 25,000 watt spikes without damage.
