This High Pressure Control Switch is an essential safety component designed for HVAC and refrigeration systems. Engineered to protect your cooling equipment from excessive internal pressure, this fan-disc style high-limit switch ensures reliable system performance and prevents compressor damage. The switch is calibrated to automatically open the electrical circuit when the system pressure reaches a high-limit threshold of 405 PSI, halting operation to maintain safety. Once the pressure levels return to a safer range of 300 PSI, the switch closes, allowing the system to resume normal operation. This durable pressure limit control is a common replacement part for maintaining the efficiency and longevity of residential and commercial air conditioning and heating units.

Application: Commonly used in air conditioning units, heat pumps, and refrigeration systems as a high-pressure safety cutout and compressor protection device.
Specifications: Opening Pressure: 405 PSI; Closing Pressure: 300 PSI; Type: Automatic Reset High Pressure Switch
