Three phase series (208 V, 415 V or 480 V) include fixed (D1)
or remote (D1R) LED or LCD options, e.g. ESP 415 D1,
ESP 415 D1/LCD, ESP 415 D1R, ESP 415 D1R/LCD

Temporary Overvoltage rating is for a maximum duration of
5 seconds tested to IEC/BS EN 61463
(3)
Min. permissable load is 5 V DC, 10 mA to ensure reliable operation
(4)
The maximum transient voltage let-through of the protector
throughout the test (±10%), phase to neutral, phase to
earth and neutral to earth
(5)
The electrical system, external to the unit, may constrain the
actual current rating achieved in a particular installation
(6)
Rating is considered as the current capability of the protector
for equipotential bonding near the service entrance
