Ranco O10-1402 Single Pressure Control
The Ranco O10-1402 is a single pressure control switch designed for HVAC systems. It operates with an SPST contact form that opens on pressure fall and features an automatic reset. The control handles a pressure range from 12 in Hg minimum to 50 psi maximum.
Suits technicians needing a 1/4 in flare connection
This control suits technicians who need a 1/4 inch female flare connection and a pressure differential adjustable between 5 psi and 35 psi. It supports multiple AC voltages including 120V, 240V, 24V and 277-600V. Buyers who require a manual reset or a different contact configuration should look elsewhere.
Pressure range 12 in Hg to 50 psi decides fit
The operating pressure range of 12 in Hg vacuum to 50 psi positive pressure is the primary specification that determines compatibility. The switch actuates on falling pressure within this window. Verify your system's cut-in and cut-out requirements match this range before purchasing.

Questions about this item
How can I confirm the Ranco O10-1402 is working correctly after installation?
Apply pressure within the 12 in Hg to 50 psi range and verify the SPST contacts open on pressure fall at the set point, then close automatically when pressure rises above the 5 to 35 psi differential.
What components are included with the Ranco O10-1402 and what must be purchased separately?
The control includes a 1/4 in female flare pressure connection for direct line mounting; tubing, flare fittings, electrical wire and a NEMA-rated enclosure are not included.
Which voltage rating should I select for the Ranco O10-1402 in my application?
Choose the model rated for your supply voltage — available ratings are 24V AC, 120V AC, 240V AC or 277-600V AC — matching the control to the circuit it will switch.
