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. Under fault conditions, the remote display will go
blank if the L1 phase loses power or becomes faulty.
This is due to the isolation requirements needed for circuitry
mounted externally to the main protector unit
(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
