Mechanical Relay Power Controllers

We carry all styles of power controllers to fit your process needs.  Phoenix Thermal Supply  has Mechanical switching relays for definite ON/OFF closure in applications where you need 100% on or 100% off power.  An example of this would be a LIMIT relay application.  This can be used for a Safety cut-off for over-temperature protection.

Other areas that a definite purpose mechanical contactor can be used are where precise temperature control is NOT necessary.  Mechanical relays will allow over-temperature shooting and under-temperature drooping during the cycle.  Styles of mechanical relays that we cover are ice cube relays, standard mechanical relays, mercury relays, & e-safe relays.  Our sales engineers can help you select the correct product for your process.
