CT8 Thermal Overload Relays

Direct-Mount Thermal Overload Protection For Connecting To CA8 Series Contactors

The CT8 is an economical thermal overload relay that includes standard features like "Differential tripping", Automatic/Manual reset modes, and isolated alarm circuit contacts.

The consistent high quality of Sprecher + Schuh thermal overload relays is ensured by a complex current calibration procedure performed after each unit is at full operating temperature. Calibration is performed at the largest and smallest current the overload can handle. The accurate time/current characteristic curve obtained in this manner guarantees reliable motor protection every time.
