Transient voltage surges are short-term deviations from a
desired voltage level or signal that can occur at any time.
Such changes can result in an electronic device
malfunction, or cause extensive damage. Also termed
"spikes" , these occurances take place as a result of
magnetic field/inductive coupling or whenever the line
current is interrupted. They can originate from either
inside a facility, or derive from outside utility lines.
Sources within a facility involve loads that are switched,
such as electric motors that are turned ON and OFF.
Outside transient influences involve utility grid switching.
Leviton Panel Mounted devices are designed to provide
protection for microprocessor-based equipment in
industrial and commercial establishments from high
voltage transients.
