Description
The Schneider Electric (Square D) 9038DG8N5 is a heavy-duty float switch engineered for dependable liquid level detection and control in a wide range of commercial and industrial HVAC, hydronic, and mechanical system applications. Backed by the trusted Square D name — a globally recognized leader in electrical control and automation — this float switch is built to deliver consistent, long-lasting performance in demanding environments.
Product Overview
Float switches are essential components in systems where liquid levels must be monitored and controlled automatically. The 9038DG8N5 actuates when the float rises or falls with the liquid surface, triggering connected pumps, alarms, solenoid valves, or other control devices to maintain safe and efficient operating levels. This makes it ideal for use in boiler feed systems, condensate receivers, sump pits, cooling towers, and similar hydronic or process fluid applications.
