ASCO Sc30D Tripoint Single Stage Adjustable Pressure Switch

ASCO SC30D Tri‑Point Pressure Switch is a single‑stage, adjustable deadband switch in ASCO’s S‑Series that combines a rugged switch unit with a compatible transducer to monitor and regulate pressure in air, water, oil, and corrosive-fluid service across industrial automation and process systems. Its Tri‑Point design uses an alternating fulcrum balance to drive one or more snap‑action contacts, with all wiring terminals, adjustments, and front‑facing scales accessible for quick field setup, and it comes in general‑purpose, watertight, or explosion‑proof enclosures, with options for fixed or full‑range deadband and optional manual reset. Because the exact setpoint depends on the paired transducer, typical SC30D switch‑point ranges include 1–18 psi, 0–0.975 psi, 0.7–9 psi, or 5–60 psi, and the repeatability is +1% of the operating range.
