Présentation du produit
The ABB PR122/P-LSIG E1-E6 1SDA058198R1 Overcurrent Release is a precision-engineered electromechanical protection module designed to safeguard circuit breakers and switchgear against overcurrent conditions. Its primary function is to detect current levels exceeding predefined thresholds and trigger disconnection to prevent equipment damage and ensure operational safety.
This release integrates advanced thermal and electromagnetic mechanisms to provide fast and reliable tripping. It is suitable for use in low- and medium-voltage applications, industrial plants, and process automation systems. Engineered for robust performance, the module ensures repeatable operation under high-stress conditions while maintaining electrical isolation and mechanical durability.
