Transient voltage and lightning protection surge arrester / type 2 / surge arrester - max. 400 V, 40 kA | ATCONTROL/R P(T)-T

ATCONTROL/R P protectors actuate when detecting a temporary
overvoltage, triggering the connected contactor (S1, S2). This contactor
disconnects the line thus protecting down-stream installed equipment.
When the permanent overvoltage ceases, the protector reconnects the
contactor.
The temporary overvoltage warning system is formed by 2 light indicators:
green (correct power supply) and red (overvoltage). It is provided with a test
button for checking if the installation has been properly made.
