Icm Controls Icm220-Lockout Relay, 18-30Vac
The ICM Controls ICM220 Lockout Relay (18–30VAC) is a protective control device designed to prevent repeated short cycling in HVAC systems. It works by monitoring system faults and locking out the compressor or equipment after a preset number of unsuccessful attempts, requiring manual reset. Commonly used in air conditioners, heat pumps, and refrigeration units, it safeguards critical components from damage. This relay enhances system reliability, reduces maintenance costs, and extends equipment lifespan, making it essential for maintaining safe and efficient HVAC operation.
