Liebert 180970P1 Switch

Liebert 180970P1 Switch

Maintain critical thermal management with the Liebert 180970P1 Pressure Switch, an OEM-spec SPDT high-pressure cutout designed for precision monitoring in Liebert HVAC units and computer room air conditioning (CRAC) systems. This automatic reset pressure switch (A/R) is engineered to trigger at 400 PSI, providing essential compressor protection by opening the control circuit during high-side over-pressurization. By integrating this HVAC high-pressure switch, technicians can effectively manage system safety and prevent catastrophic failures caused by restricted airflow, condenser fan failure, or refrigerant overcharge.

The Liebert 180970P1 features a rugged 400#CO (changeover) contact configuration, ensuring high conductivity and minimal contact resistance within high-demand industrial environments. Its single pole double throw architecture allows for simultaneous control of secondary alarm circuits or redundant cooling staged responses. With a compact form factor and standard 3-blade electrical terminals, this OEM Liebert switch facilitates rapid field replacement on Vertiv Liebert precision cooling equipment, ensuring consistent uptime for sensitive data center infrastructure.

Key Benefits
  • Precise 400 PSI Cutout: Ensures the high-pressure limit is strictly enforced to protect the compressor and microchannel coils from rupture.
  • Automatic Reset Logic: Eliminates the need for manual intervention once system pressures return to safe operating parameters.
  • Industrial-Grade SPDT Contacts: The 400#CO construction supports high current loads while maintaining signal integrity across multiple circuits.
  • Direct OEM Compatibility: Specifically calibrated for Liebert CRAC units, ensuring exact fitment and factory-standard performance.
Common Questions

What causes this switch to trip frequently in a Liebert unit?
Frequent trips usually indicate high head pressure, often caused by a dirty condenser coil, a failing condenser fan motor, or non-condensables in the refrigeration circuit.

How do I verify if the 180970P1 is faulty?
Using a multimeter, check for continuity across the contacts. If the system pressure is below 400 PSI but the switch remains open, the internal diaphragm or contacts may have failed.

Can this switch be used in 24V and 120V control circuits?
Yes, the SPDT contacts are rated for standard HVAC control voltages, provided the amp draw does not exceed the component’s technical contact rating.
