AIR CIRCUIT BREAKER

MTW1-2000, MTW1-3200, MTW1-4000, MTW1-6300, MTW1-7500

The MTW1 series of intelligent breakers are expertly crafted for integration into AC 50Hz distribution networks, with a rated voltage of 400V and 690V, and a robust rated current spanning from 400Ato7500A. These breakers efficiently distribute electric energy while safeguarding circuits and power equipment from potential damage caused by overloads, under-voltage issues, short circuits and single-phase earth faults . Equipped with an intelligent protection function and precise selective protection capabilities, these breakers significantly enhance the reliability of power supplies, helping to avoid

unnecessary power outages.This circuit breaker is designed to endure an impulse withstand voltage of8000V at altitudes up to 2000 meters, with adjustments made according to differing altitude standards, not surpassing 12000V.

This product is fully compliant with the rigorous standards of GB14048.2 for low-voltage switchgear and control equipment. It meets the low-voltage circuit breaker standards as per IEC60947-2 for low-voltage switchgear and controlling equipment, second part: low-voltage circuit breakers.
