Current Switch Adjustable 0.65-180A

APPLICATIONS

The Adjustable Current Switch is designed for use in any AC current monitoring application in which you are looking to monitor a particular piece of equipment for equipment failure, preventative maintenance, status, and electrical load status. The current switch should be installed on the line side of the power to the electrical equipment. The current switch includes a Patented 35 mm Din Rail mounting foot for easy installation in panel mount applications. The split-core works great in retro applications and for use on service technicians’ vehicles since one part will work in most applications and can be easily installed without disconnecting any wires. The adjustable current switch can be used to determine the run time of your equipment as well as basic load trending applications where you want to know when how long your piece of equipment runs when logging the contact closures on your building management system or PLC.
