Parker Hannifin 210221 Leaded Float Switch Assembly Replacement for Refrigeration Systems

The Parker Hannifin 210221 is a leaded float switch assembly designed for refrigeration applications, specifically for monitoring and controlling refrigerant liquid levels. This assembly serves as the direct replacement for discontinued part number 208874, providing a drop-in solution for existing installations.

Key Features:

• Leaded switch assembly without CE certification, compatible with standard North American refrigeration systems
• Normally open switch that closes when the float rises to the set level
• Single pole double throw (SPDT) electrical contact for versatile wiring configurations
• 24-inch (610mm) lead length for flexible installation
• Rated for 10A at 120 VAC, 10A at 240 VAC, or 1/2A at 125 VDC
• Operates with refrigerants having specific gravity range of 0.55 to 1.70
• Corrosion-resistant construction including stainless steel float chamber

This float switch is used to control solenoid valves, activate electrical controls, energize magnetic starters for pumps and compressors, and serve as a safety device to sound alarms or activate lights during high or low liquid level conditions. The assembly features color-coded wiring for easy installation, with normally open and normally closed contacts clearly identified.
