TransAX™: A superior protection !
Usually there are two methods used to absorb
transients: RC networks and Metal Oxyde
Varistors (MOV). Both methods are unsufficient
in certain cases.
The new TransAX™ option eliminates the
problems normally associated with RC networks
and MOV’s.
It is an active component that can quickly switch
very high currents. Instead of absorbing
excessive energy endlessly, at a predetermined
programmable trip point it passes the energy
back to the line. During normal operations the
switch sits idle and is always ready to activate.
