Manitowoc 13577 High Pressure Cutout Switch 350/250 Psi

Product Description

The MANITOWOC 13577 is a normally closed high-pressure cutout (HPC) switch designed for use in commercial ice machine refrigeration systems. It opens the control circuit when refrigerant discharge pressure reaches 350 psi and automatically resets when pressure drops to 250 psi, protecting the compressor and system components from damage caused by abnormally high head pressure. Licensed refrigeration technicians and commercial appliance service professionals install this switch as a safety control in the high-side refrigerant circuit.

This switch is intended for commercial ice machine applications where reliable high-pressure protection is required. It fits into the high-side service port or dedicated pressure port in the refrigerant circuit, typically on the discharge line between the compressor and condenser. The normally closed configuration keeps the control circuit active under normal operating conditions, interrupting it only when the set-point pressure is exceeded.

Key Features

• Normally closed (NC) contact configuration for fail-safe pressure protection
• Cut-out set point at 350 psi to interrupt compressor operation on high head pressure
• Auto-reset at 250 psi when system pressure returns to safe operating range
• Designed for high-side refrigerant circuit installation in commercial ice machines
• OEM replacement part sourced from Manitowoc Ice parts and accessories

Compatibility

Designed as an OEM-style replacement high-pressure cutout switch for Manitowoc Ice commercial ice machine refrigeration systems.

Installation Notes

Installation should be performed by a licensed HVAC-R or refrigeration technician in accordance with applicable local codes and EPA Section 608 refrigerant handling regulations. Recover refrigerant and depressurize the high-side circuit before removing the existing switch. Verify the replacement switch threads and pressure ratings match the original before installation. Restore refrigerant charge and confirm proper cut-out and reset function before returning the unit to service.
