HP SWITCH (MRD-12-00628-34)

The HP Switch in transport refrigeration plays an integral role in regulating system operation by interfacing with control circuitry and pressure-sensitive components.

• System Monitoring: It continuously tracks refrigerant pressure levels on the discharge side of the compressor.
• Electrical Interlock: When pressure thresholds are exceeded, the HP switch interrupts electrical flow to key components, such as the compressor clutch or controller.
• Integrated Control: The switch communicates with onboard electronics to prevent operation under unsafe conditions, promoting responsive control logic.
• Reset Options: Units may feature either automatic resets for transient faults or manual resets for critical events that require technician review.
• System Feedback: Data from switch activation can assist in evaluating system load, airflow efficiency, or the need for refrigerant system servicing.

The HP switch acts not just as a passive safety device but as a smart control interface that supports automated, protected refrigeration system performance.
