Description
Transient/Surge Absorbers
(TSA’s) provide system designers with allow cost and 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 models
available: single-phase (1P), 3-phase delta 3-wire (3PD),
or 3-phase wye 4-wire (3PY). Each model is available to cover
nominal AC voltages of 120, 208, 240 and 480.
TSA’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 24,000 watt spikes without damage.
