Detailed description in the Design Engineer's manual.
(2)
Locking Function available via Ekip Connect.
(3)
For all the UL versions the maximum time allowed by the trip unit is 0.4 seconds. If a higher value is set, the trip unit signals the error and forces
the parameter to 0.4 seconds.
(4)
Directional Zone Selectivity works as an alternative to S and G Zone Selectivity.
(5)
Protection not active for voltages <30V.
(6)
The protection does not detect the direction of fault current for voltages < 5V.
