Intelligent Universal Circuit Breaker - Low Voltage Electric Components
Introduction: Intelligent Universal Circuit Breaker [Low Voltage Electric Components]MZW2 Series Intelligent Universal Circuit Breaker has assimilated all advantages of domestic and foreign various intelligent circuit breakers. It has such features as compact structure, high reliability, short partition time and without flying arc. Besides many protection functions, it also has many auxiliary functions, such as: ammeter, voltmeter, power factor meter, malfunction finding, self-diagnosis MCR and so on. It has communication interface and can realize four remote control functions. The product has passed IEC60947-2(97) international latest EMC standards and various strict model test examinations. Its chief technical specifications have reached the advanced level of similar products.
Functions and Categories - Intelligent Universal Circuit Breaker
MZW2 Series Intelligent Universal Circuit Breaker (hereinafter refers to the circuit breaker) is of 400V, 690V rated voltage, AC 50Hz, 400A~6300A rated current. It is mainly applied to power distribution system for distributing electric energy and protecting the circuit as well as the power supply devices against overload, short circuit, single phase grounding, lack of voltage and so on. This circuit breaker has many intelligent protection functions and can provide selective protection with accurate movement, which can avoid unnecessary power failure and improve the reliability of power supply. It has open communication interface which can realize four remotes to meet the demands of the group center as well as automation system.
Its pulse voltage tolerance is 8000V at the altitude of 2000M (different altitudes can be rectified according to the standards and the maximum is 12000V). The intelligent button releaser and sensor are not attached with the circuit breaker. It can be used for isolation.
The circuit breaker meets GB14048.2 “Low Voltage Switch Equipments and Control Equipments Low Voltage Circuit Breaker” and IEC60947.2 “Low Voltage Switch Equipments and Control Equipments” standards.
