A70, A72 Series Temperature Controls for Refrigeration and Heating

The A70 single-pole and A72 two-pole controls are supplied in a wide selection of ranges to meet most application needs. See ìTemperature Ranges.î Models may be supplied to open a circuit on temperature increase or close a circuit on temperature increase as required. An A70 single-pole control may optionally include a separate reverse-acting auxiliary contact. Models are available with a SPDT enclosed Penn switch.
All Series A70, A72 controls are designed for use only as operating controls. Where an operating control failure would result in personal injury and/or loss of property, it is the responsibility of the installer to add devices (safety, limit controls) or systems (alarm, supervisory systems) that protect against, or warn of, control failure.

  • Long life contact structure with high contact force right up to break - no bounce on make.
  • Make reset models are ìtrip-freeî.
  • Ranges available to cover most applications.
  • Auxiliary contact can be used to actuate an alarm circuit when the main contact opens.
  • Two-pole construction provides a number of application advantages (see ìGeneral Descriptionî).
  • Heavy gauge ìlow profileî stainless steel element cup to protect against mechanical damage.
