The Benefits of Type E/F Motor Protection Circuit Breakershe
in larger enclosures, increased panel complexity, decreased configuration flexibility, and
a higher overall installation cost.

Basics:
Part 1, Contactors
There had to be a better way — Simplify the motor disconnect, control, and protection
processes by reducing the number of panel components by creating a multi-functional,
standalone replacement component.
