WebThe D curve is delayed by 4 seconds when compared to the K curve. The additional 4 seconds allows a circuit more time to “ride through” high in-rush at start-up and prevent nuisance tripping. Thermal Element Bandwidth: The K curve tripping bandwidth at 2X rated current is between 6 and 350 seconds. WebJul 1, 1996 · At this point, the tripping time is approximately 25 % compared to that of a cold overload relay. Curve 3 shows that a NEMA Class 20 overload relay, even at warm condition, may not trip within 2 min of a 150% overload. Note that none of the curves shows a tripping time under 2 min from a cold start.

Tripping Characteristics of MCB: B,C,D,K,Z Trip Curves

WebThe tripping curve is a definite time curve with a constant tripping time. Short-time overcurrent protection is based on the true RMS current of phases and neutral, up to harmonic 15. In order to trip on an intermittent fault, the control unit accumulates the intermittent currents in the short-time tripping range that do not last long enough to ...
