Embraco 2321004-ESP Compressor Overload Protector

The Embraco 2321004-ESP is a thermal overload protector designed to safeguard refrigeration and HVAC compressors from electrical overload conditions. This essential safety component monitors electrical current flowing through the compressor circuit and automatically interrupts power when current exceeds safe operating thresholds, preventing motor damage and potential system failures.

Key Features:

• Precision-calibrated thermal protection for consistent, reliable performance
• Automatic reset design restores operation once safe temperature conditions return
• Durable construction built to withstand demanding refrigeration environments
• Direct replacement for OEM Embraco/Nidec compressor applications
• Compact form factor for easy installation on compressor terminals

This overload protector is commonly used in commercial refrigeration systems, walk-in coolers, ice machines, and residential HVAC equipment. By detecting abnormal current draw caused by locked rotors, low voltage, or single-phasing conditions, the 2321004-ESP protects valuable compressor investments and helps prevent costly equipment downtime.
