MRA12054-12026
The Carrier MRA12054-12026 Compressor Overload is a safety device crucial for Carrier HVAC systems. It safeguards the compressor, the heart of the system, from electrical overload damage. Functioning like a sentry, the overload relay continuously monitors the current draw of the compressor. If the current surpasses safe limits, the relay trips, interrupting power to the compressor and preventing burnout. This compact device, weighing only 0.07 lbs and measuring 3 x 1 x 1.25 inches, is designed for use with 208-230V systems. By automatically protecting the compressor, it ensures the longevity and efficient operation of your Carrier HVAC system.
