Ranco P30-5826 Lube Oil Pressure Control with 120 Second Time Delay

The Ranco P30-5826 is a lube oil protection control designed to guard pressure-lubricated refrigeration compressors against major damage caused by loss of oil pressure. This safety control features a 9 psid fixed differential pressure range with a 36-inch capillary tube and 120-second time delay module.

How It Works:

This control utilizes the built-in P30 Time Delay Switch to start timing when oil pressure drops below operating requirements. The timer tracks oil pressure recovery within the set 120-second period and alerts the control circuit to open and stop the compressor when the recovery period is exceeded, preventing catastrophic compressor damage.

Key Features:

• 9 psid fixed differential pressure range
• 120-second time delay for oil pressure recovery
• 36-inch capillary with flare nut connection
• Manual reset function
• Standard alarm circuit
• Super Cap® capillary protection system
• Ambient temperature compensated
• High impact, non-conductive cover
• Field replaceable switch module
• Front-located captive cover screw
• Industry standard circuitry and terminal identification
• 720VA pilot duty rating at 120/240 VAC

Suitable for use with commercial refrigeration systems and pressure-lubricated compressors. This control is manufactured by Robertshaw under the Ranco brand and meets industry standards for oil pressure safety controls.
