The following are the trip curves of the protections available with Ekip G Hi-Touch trip units.
NOTE: the protections S(V) with S2(V), and RQ with RQ2, share the same calculation algorithm.
For graphical convenience only one curve is shown for each protection (S(V) and RQ in the
previous chapters).
