High-Pressure SPST Pressure Switch, 300 PSI Open / 200 PSI Close

This high-pressure SPST pressure switch is for HVAC service professionals who need to control condenser fan cycling based on system pressure. It opens on a pressure rise at 300 PSI and closes at 200 PSI to support pressure-responsive operation.

The switch uses a snap-acting, hermetically sealed stainless steel sensor and a 1/4 in. SAE female flare connection with a valve core depressor for direct mounting. It has a 0 to 650 PSI pressure range, 5,000 PSI burst pressure, and a 100,000-cycle rated load life. Electrical ratings are 24, 120, or 240 V at 50/60 Hz, 6 RLA, and 36 LRA. Ambient operating temperature is 20°F to 176°F, and fluid temperature is 60°F to 250°F.

Key Features:

• 300/200 PSI switching: Opens at 300 PSI on pressure rise and closes at 200 PSI for condenser fan cycling control.
• SPST snap action: Provides responsive switching as pressure changes.
• Sealed stainless steel sensor: Uses a hermetically sealed sensing element for pressure detection.
• 1/4 in. SAE flare fitting: Allows direct mounting with a valve core depressor connection.
• 0 to 650 PSI range: Supports pressure monitoring within the specified operating range.
• 100,000-cycle rated life: Provides a stated cycle-life rating for recurring switching applications.

Choose this compact pressure switch for HVAC condenser fan cycling applications requiring an SPST switch that opens at 300 PSI and closes at 200 PSI.
