What is a disconnect switch used for?

Select based on your system voltage, amperage, and the size of the equipment (HP). Also choose the enclosure type depending on whether the installation is indoor (NEMA 1) or outdoor (NEMA 3R).
NEMA 1 is designed for indoor use in dry environments, while NEMA 3R is built for outdoor use and protects against rain and weather.
Yes, these switches can be wired for 240V single-phase use depending on your setup.
