Klixon® 46PS Series Pressure Switch for HVAC, Commercial, and Industrial Uses

-10°C to 85°C, Automatic Reset HVAC Pressure Switch

Features and Overview

  • Electrically rated up to 480 Vac
  • High current capability
  • Capable of 2.5 million cycles (requires Sensata/customer specification closure and validation testing before application approval)

A breakthrough in Sensata Technologies’ pressure switch technology enables direct line break capability in applications that have been traditionally controlled in pilot duty circuits by contactors or relays.

The 46PS HVAC Pressure Switch is capable of breaking 2 amp loads at 480 Vac for 2.5 million cycles (requires Sensata/customer specification closure and validation testing before application approval).  It is ideal for cycling condenser fan motors to maintain an acceptable condensing pressure during low ambient temperature conditions.

In applications such as split room air conditioning systems, the 46PS as a head pressure control can result in significant cost savings when used instead of a pilot duty switch and relay.  Other potential uses include fluid pressure sensing in commercial and industrial applications.
