The Eaton Cutler-Hammer KT3400T serves as a molded case circuit breaker trip unit within the Series C line. This unit is intended for three-pole applications, capable of safely handling a rated current of 400 A. It employs a thermal magnetic protection system that effectively safeguards electrical circuits from overload and short-circuit conditions.
The KT3400T is built to perform in environments where operating humidity does not exceed 80% (non-condensing), ensuring reliability in both operational and storage scenarios with similar humidity constraints. Designed for installation at altitudes reaching up to 1000 meters above sea level (MSL), this trip unit performs efficiently under various geographical conditions.
Temperature resilience is notable; it functions within a range of 0°C to 40°C during operation, and also endures identical temperature limits for storage. These specifications allow for versatile application across different industrial contexts, promoting stability and safety in electrical distribution systems.
