Electronic Adjustable MCCB HKKM1E

HKKM1E series Rated insulation voltage: 800V Equipped with the advanced SCM Operation of the breaker can be controlled by means of acquisition, analysis and disposal of information got from the transformer Can be classified as type M (the higher breaking capacity) and H (the highest breaking capacity) Mounted horizontally or vertically Compact size and high breaking capacity Short arc-over distance (some breakers are of zero zrc-over distance), isolation function and shock-proof Can provide accurate protection function which is suitable for modern electric power distribution systems Differ from the traditional thermo magnetic release with two-section protection, the breaker has three-section protection, each parameters can be adjusted Used in the circuit with the working frequency of 50Hz, rated working voltage of 400V and rated current up to 1,250A Distribute electrical power and protect the circuit and power equipment from over-load, short-circuit, over/under-voltage Also be used to protect motors, turn-on or turn-off the circuit and start motors not frequently Applied standards: IEC60947-2(1995) and GB14048.2 Applied condition: can be used in the same field as that of HKKM1 breaker except in the nuclear industry
