Ashcroft LPAN4HT25 Pressure Switch

Ashcroft LPAN4HT25 Pressure Switch is a four-port LP-Series snap‑action pressure switch designed for reliable process control in harsh industrial environments. The LPAN4 family provides a single adjustable setpoint with deadband and is built into a NEMA 4/4X enclosure with IP66 protection, making it suitable for washdown and corrosive settings. This model specifies a 60 psi nominal range and operation at 125/250 VAC (WL15-2), with four pressure connection ports to simplify piping layouts. It carries UL, CSA, CE, and CRN approvals and RoHS compliance, reflecting Ashcroft’s emphasis on safety, regulatory adherence, and environmental responsibility. Typical applications include pressure control, safety shutdown, and alarms for pumps, compressors, and turbines, across refineries, chemical plants, power generation, water treatment facilities, and other demanding industrial systems requiring a field‑adjustable setpoint and dependable performance. The LP-Series is designed for straightforward field calibration and wiring of its snap‑actuated switch elements, enabling engineers to tailor deadband and response to match specific process needs while maintaining reliability in tough environments.
