(1)
Temporary Overvoltage rating is for a maximum duration of
5 seconds tested to BS EN/EN/IEC 61643
(2)
Minimum permissable load is 5 V DC, 10 mA to ensure
reliable operation
(3)
The maximum transient voltage let-through of the protector
throughout the test (±10%), phase to neutral, phase to
earth and neutral to earth
(4)
The electrical system, external to the unit, may constrain the
actual current rating achieved in a particular installation
(5)
Rating is considered as the current capability of the protector
for equipotential bonding near the service entrance
