Trip class:
AC Class – Trip is guaranteed for alternating sinusoidal currents, whether applied suddenly or increasing slowly.
Class A – Trip is guaranteed for residual alternating sinusoidal currents, as well as residual pulsating DC currents, whether applied suddenly or slowly.
Trip curve – Curve C protection (5-10 In) and control of circuits against overloads and short circuits, protection for resistive and inductive loads with low inrush current.
