Tripping is ensured for sinusoidal, alternating residual currents as well as for pulsed DC residual currents, whether they be quickly applied or slowly increase.
Tripping curve
B curve (3-5 In) protection and control of the circuits against overloads and short-circuits; protection for people and big length cables in TN and IT systems. C curve (5-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.
Solve nuisance tripping problems for good. Our guide helps you diagnose why your breaker trips on startup and shows how to select the correct B, C, or D curve for motors, pumps, and other loads.
