These are designed to shut down the electrical supply to the pump on your flammable liquid lines or hydraulicly driven machinery using a fusible link technology. REMEMBER, if the 120 Volt power to the controller goes off, then the 3-phase pump or equipment will shut down too!!
On large equipment, you may need to wire several of these in a series and a "halo' ring around your machine. It is also suggested that a pilot lamp be installed at eye level so you can be sure power is getting from the source, through the roof or elevated Fire Safety Switches and is available at your controller without having to get to the roof level when an outage occurs. Replacement links are available from Globe. These switched will meet your insurance company's requirement for "auto shutoffs" on your equipment.
