The objective of ERMS is to reduce arcing fault time duration.

Explanation:
Reducing arcing fault time duration minimizes the energy released during an arcing fault. Arcing faults can release a lot of heat and molten material in a very short time, so the quicker the fault is detected and interrupted, the less damage, fire risk, and exposure to personnel. Increasing the duration would allow more energy to flow, increasing risk. Eliminating arcing entirely isn’t practical, though systems aim to interrupt as fast as possible. Stabilizing the arc doesn’t address the problem of excessive energy over time. So the objective is to reduce the duration of the arc.
