What to do if ABB Emax E1 Power Tool trip times are higher than expected?
- K
  Kathleen MyersAug 3, 2025
  If the trip times for your ABB Power Tool are higher than expected, consider these potential causes and solutions: * The threshold may be set too high. If so, correct the threshold. * The curve might be too high. If so, correct the curve. * The curve type might be set to "t=k/I2". If so, select curve type "t=k". * The neutral selection could be incorrect. If so, correct the neutral adjustment.

What to do if ABB Power Tool experiences a rapid trip with I3=Off?
- T
  Todd BrownAug 15, 2025
  If your ABB Power Tool experiences a rapid trip with I3=Off, it's likely due to an instantaneous trip (Iinst tripped). This is usually caused by a short-circuit with high current (FN short-circuit with high I).

Why the trip test cannot be run on ABB Power Tool?
- T
  Taylor DiazAug 27, 2025
  The trip test on your ABB Power Tool may not run due to several reasons: 1. The busbar current is greater than 0. 2. The TC (Temperature Control) is not connected. Check TC connection. 3. The PR030/B unit is not connected. Connect the PR030/B unit.
