High performance surge protector for 230V ~ applications
Snap-on housing for DIN rail or wall mounting
Visual function indicator (green and red LED)
Remote signalling contact (Pk)
EnerPro220Tr/20kA is used for
categories C and D 230V ~ inputs.
Its use is especially recommended
where no primary and/or secondary
protection is installed. It is built into
an easy to handle snap-on housing
for 35mm DIN rail mounting.
A green LED signal shows that
the operating voltage has been
achieved and that the protective
circuit is in full working order.
The protection elements are automatically
extinguishing valve
conductors which lead to the PE
respectively high performance
varistors placed between phase and
neutral conductor. Once they have
acted as surge arresters with subsequent
discharge of the partial lightning
current pulses, the follow-on
currents are switched off automatically.
The gas-filled performance
arrester leading to the
PE blocks any leakage current
pulses that may come from the
varistors.
EnerPro220Tr/20kA has a thermal
disconnection device which will
respond if the varistors emit excessive
leakage current pulses due
to overloading. The thermal disconnector
is situated in the cross
section thus cutting off only the
surge protective device from the
mains (no operating disruption);
when this happens, the red LED
signal will light up and the optional
potential-free contact will open.
