Relays and Contactors
Conductors and relays are a staple for switching larger loads than a pilot device or PLC output can handle.
You'll see how to use contactors to build reversing motor starters and two often-overlooked components: the manual motor starter and overload protection. We'll walk through how to properly interlock your contactors, both mechanically and electrically, and how to correctly wire the overload's auxiliary contacts to protect your motor. You'll also learn the crucial difference between a contactor's amperage rating and its horsepower rating.
