"Utilizing Solid State Relays in 3-Phase Heating Control Applications"

Not much has changed since three-phase Solid State Relays (SSRs) became available after the introduction of single-phase SSRs in 1970.

The first ones were nothing more than three individual SSRs with a common input connection packaged in a single housing. Today, however, much has changed regarding the attributes and characteristics of power circuits and the demands of three phase loads — specifically for heating control applications. This report provides a needed update on proper selection of three-phase power systems; the characteristics of common three phase heating loads; and their use in for heater control applications.

You’ll learn how & why:

  • Three-phase power provides the most consistent current supply, with at least two phases always delivering power to the load
  • Three-phase systems tend to be more economical, using less conductor material to transmit power, sometimes requiring less space
  • Three-phase systems produce a magnetic field rotating in one direction to helps simplify motor design and allow a motor to reverse a motor’s direction by swapping two of the three phases
