Danfoss 060b205066 Differential Pressure Switch MP54

Product Description

The DANFOSS 060b205066 is a differential pressure switch in the MP54 series, designed to monitor pressure differentials in refrigeration and HVAC systems. It features a manual reset function, meaning the switch must be manually reset after a pressure trip event before the system can restart. The pressure connection uses a 1/4 inch flare nut fitting. The enclosure carries an IP20 rating, suitable for installation in protected indoor equipment panels and control enclosures. This switch is installed by licensed refrigeration technicians and HVAC mechanics as a safety or control device within refrigerant-circuit and pressure-monitoring applications.

The MP54 differential pressure switch is used in commercial and light-commercial refrigeration equipment, chillers, and HVAC systems where monitoring the difference between two pressure points is required for system protection or control logic. Typical installations include compressor protection circuits, oil pressure safety applications, and filter-drier monitoring setups. The manual reset configuration is common in safety-critical applications where automatic restart after a fault is not permitted by system design or code.

Key Features

• Manual reset function requires deliberate operator action before system restart after a pressure trip
• 1/4 inch flare nut pressure connections for secure, leak-resistant refrigerant-side hookup
• IP20 enclosure rating suitable for protected indoor panel installations
• Maximum working pressure of 17 bar for compatibility with medium- and high-pressure refrigerant systems
• Part of the Danfoss MP54 switch and thermostat product group, a recognized platform in commercial refrigeration controls

Compatibility

Designed as an OEM-style replacement or service component for refrigeration and HVAC systems requiring a differential pressure switch with manual reset, 1/4 inch flare nut connections, and a maximum working pressure of 17 bar.

Installation Notes

Installation should be performed by a licensed refrigeration technician or HVAC mechanic. Recover or isolate refrigerant and depressurize the circuit before disconnecting or installing any pressure switch. Verify that system working pressure does not exceed the rated maximum of 17 bar. After installation, confirm all flare nut connections are properly torqued per the equipment manufacturer guidelines and check for leaks before returning the system to service.
