Intelligent Circuit Breaker cw1-2000 / 3 / 630A

Scope Xiamen Hui to electrical intelligent circuit breaker, product technical parameters, classification and selection Note: a: Scope HMW2-2000 intelligent circuit breaker for 50HZ, rated working voltage up to 690V, rated current 630A-2000A distribution network for the distribution of power and protect circuits and power supply equipment from overload, harm under-voltage, short circuit, single-phase ground fault in the middle of the distribution network. Intelligent circuit breaker protection with intelligent, selective protection accurate, can improve the reliability of power supply, effectively avoid false blackout. Intelligent circuit breaker with a communication interface developed to improve the efficiency of the fieldbus connection. And to achieve the "four remote" function, to meet the control center and automation systems. Configure the transformer leakage and leakage protection intelligent controller can achieve all-weather. Intelligent circuit breaker with isolation function, rated current 630A below the circuit breaker can also be used 50HZ, 400V power distribution network as a motor overload, under voltage, short circuit, phase and ground fault protection. The distribution network as a motor overload, under voltage, short circuit, phase and ground fault protection. Under normal conditions, the intelligent circuit breaker as infrequent line conversion or frequency conversion motor use. Intelligent circuit breaker in line with GB14048.1-2006, GB14048.2-2008, GB14048.4-20032 national standards. Two: Use category classification in accordance with, installation, transmission mode and other details are as follows: 1, according to the use of category: the main circuit A, B, AC-3 auxiliary AC-15, DC-13 2, Installation: Fixed drawer 3 , Transmission: Manual operation of the motor drive 4, series: 3 4 5 suitability isolation points: for isolation, is not suitable for isolation 6, repairs are needed: in need of repair, maintenance-7, release by type: Intelligent Controller shunt release, undervoltage release 8, Intelligent Controller Category: functional, basic features, coupled with intelligent function type, this function with smart functions and communication interface type. Three: a normal working conditions, ambient air temperature does not exceed the upper limit of +40 degrees; lower limit of not less than 5 degrees; 24H average does not exceed +35 degrees; for use in ambient temperatures above +40 degrees or below is not Users shall consult the manufacturer below -5 degrees. 2, the installation site altitude of not more than 2000 m 3, the maximum temperature is +40 degrees, relative humidity less than 50%, at lower temperatures can have a higher relative humidity. 4. Pollution levels for three 5, intelligent circuit breaker installed in the cabinet, door installation, protection grade IP40. 6, intelligent circuit breaker main circuit and undervoltage release coil, power transformer primary coil installation category four, the rest of the secondary circuit, the control circuit installation category 2, the main circuit breaker intelligent universal and less voltage release coil, power transformer primary coil installation category 4, regional auxiliary circuit, control circuit installation category 3. 7, using the category of class B. 8, transport and storage conditions of intelligent circuit breaker: -25 degrees to +55 degrees up to 70 degrees in a short time. 9, intelligent circuit breaker should be installed in no danger of explosion, conductive dust, no corrosion and damage the insulation where intelligent circuit breaker vertical gradient of not more than 5 degrees.
