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)
Rating is considered as the current capability of the protector
for equipotential bonding near the service entrance
(5)
The electrical system, external to the unit, may constrain the
actual current rating achieved in a particular installation
