(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
