The emergency electrical cutoff switch to CUTOFF removes power from which component?

Explanation:
The emergency electrical cutoff is designed to shut down the engine by interrupting fuel supply through the high‑pressure line. In this helicopter, removing power from the 2000 psi isolation valve causes that valve to close, isolating the high‑pressure fuel and stopping fuel flow to the engine. With fuel no longer reaching the engine, rapid shutdown is achieved and fire risk is reduced. The generator and battery remain part of the electrical power system and are not the target of this emergency switch, and the fuel pump is controlled separately, not by this cutoff.
