The 250A 3P MCCB Molded Case Circuit Breaker is a high-performance electrical protection device designed for industrial applications. This circuit breaker combines advanced international technologies to provide reliable overload, short circuit and under voltage protection for power lines and equipment.
With a rated insulation voltage of 800V and suitable for AC 50Hz systems, this MCCB operates at working voltages up to 690V. It features three breaking capacity classifications: L type (standard), M type (high breaking), and H type (ultra-high breaking) to meet various application requirements.
The breaker can be installed in either vertical or horizontal orientation and is designed for use in environments with elevations up to 2000 meters. It operates reliably in ambient temperatures ranging from -5°C to +40°C, with pollution level 3 and installation category III/IV ratings.
Key features include compact size, high breaking capacity, short arcing characteristics, and excellent vibration resistance. The instantaneous action characteristic setting is 10In±20% for distribution protection and 12In±20% for motor protection applications.
This MCCB is ideal for both land and marine applications where reliable circuit protection is required. The thermo-electromagnetic (double) tripping device ensures precise protection coordination, while the fixed installation design provides stability in various operating conditions.
