Description
Generators create short voltage spikes (surges) at their out-
puts particularly when the load changes or when they are
switched off under load. However voltage spikes can also
occur with mains power. Connected units and or electronic
modules can be destroyed by such voltage spikes.
The mains protector is switched between the CEE-supply socket
and the 230 V input fuse (e.g. Truma AC-P 10 A / 30 mA). The
input voltage is compared to a cutout threshold (270 V). If the
mains protector records a voltage which exceeds the cutout
threshold, the mains protector switches off all poles of the out-
put (i.e. phase and neutral) within milliseconds.
The output for the connected input protection stays off dur-
ing approx. 6 seconds, if the mains protector detects a volt-
age spike and switches off. The mains protector unblocks the
output after this time has elapsed. The output stays off and
the off-time recommences, if the mains protector registers a
further voltage spike during the off-time.

Connections and operating elements
1 2 3 4
230 V consumer output (1)
The 230 V output is for supplying the 230 V consumers.
A 230 V distribution box may be needed here.
230 V input (2)
The 230 V input is connected to the 230 V input fuse. The
power is supplied from here through the mains or by a
generator.
Test button (3)
The test button (red) simulates a voltage spike on the mains
protector. In this way the correct functioning of the mains pro-
tector can be checked. The button is actuated for a short time
to carry out a functional test. Hereupon the mains protector
switches off the 230 V output for a short time and the operat-
ing check light goes out. The operating check light lights up
again once the mains protector enables the output again.
Operating check light (4)
The operating check light (green) shows if there is 230 V on
the output. It lights up when the 230 V output is ready. The
light goes off, when the mains protector of the 230 V output
has switched off or the test button has been actuated.
