When you have two choices of current switches to install on a variety of motors, which do you choose: a fixed set-point or an adjustable set-point switch? In order to compare fixed and adjustable, safety, inventory, and installation time will be examined to find the best switch for any application.

Fixed Set-Point Switch

The fixed set-point switch allows for increased safety during installation, removing the chance of of dealing with an arc flash incident in live circuit. One issue with the fixed set-point switch is that you don't know the horsepower of each motor, forcing you to carry a variety of fixed set-point switches around. This kind of inventory can be costly and inconvenient for an installer.

The adjustable set-point switch is flexible enough to be used on a variety of different powered motors, eliminating excess inventory. With the convenience comes a safety issue with the potential of experiencing an arc flash hazard. A PPE (Personal Protective Equipment) Suit is required while installing the adjustable current switch, because of the direct contact with an energized circuit.
