CFM3E series moulded case circuit breaker is our new high-tech products. The product is characterized in advanced design, reliable performance, high technical indicators, beautiful appearance, small size and using the microelectronics technology. It has intelligent over-current protection. It is suitable for AC 50Hz with rated insulation voltage 690V and rated voltage up to690V with rated current up to 800A, mainly used to distribute electric energy and protect circuit and power supply equipment from overload, short circuit and under-voltage, also can control the unfrequent operation of motor.
The intelligent over-current release of this breaker is controlled by microprocessor, has the characteristic of three section protection, that is overload inverse time limit time-delay protection, short circuit time-delay protection and short circuit instantaneous protection. Because of its adjustable short circuit short time-delay protection, the breaker belongs to category B. This series breaker definitely can reach the requirement of protecting the load side in series from another short circuit. The product has the indicators of operation current, overload pre-warning, release power supply and self diagnose.
