Transients (surges) on a line can cause spikes or surges of energy that can damage delicate electronic components. A SPD device contains one or more _________ that bypass and absorb the nergy of the transient.
Solution
A SPD device contains one or more non linear components (Live part like varistor, gas discharge tube etc) that bypass and absorb the energy of the transient.
It also contains a
thermal protective device (internal disconnector) which protects it from thermal runaway.
