1
Temporary Overvoltage rating is for a maximum duration
of 5 seconds tested to BS EN/EN/IEC 61643.
2
The maximum transient voltage let-through of the
protector throughout the test, phase to earth and
neutral to earth.
3
The electrical system, external to the unit, may
constrain the actual current rating achieved in a
particular installation.
4
The remote signal contact (removable) adds 10 mm
to height.
