Description
The Generac 0L2917A is a 5 PSI normally‑closed (NC) low‑oil pressure switch designed to protect Generac engines by shutting them down when oil pressure drops below safe operating levels. When oil pressure reaches 5 PSI or higher, the switch opens, allowing the generator to run; if pressure falls below that threshold, it closes to trigger an automatic shutdown, preventing engine damage. This model replaces the earlier 0H1315 switch and is compatible with a wide range of Generac‑built generators, including units branded under Honeywell, Guardian, Siemens, Carrier, Watchdog, Centurion, and Bryant. The switch uses a tapered thread, requiring careful installation to avoid engine‑block damage, and features a compact brass‑body design with a 2‑pin connector.
