USES: ZBW1 Series Intelligent Universal Circuit Breaker (hereinafter referred to as circuit breaker) is applied to distribution network with AC 50Hz, Rated current 400A ~ 6300A and Rated working voltage 400V or 690V, and Used to allocate power and protection circuit and power equipment from overload, under voltage, short circuit, single-phase ground fault and other hazards. Circuit breaker have multiple protection features, high-precision selective protection, improve supply reliability. Circuit breaker have isolation function in order to ensure the safety of outage overhaul personnel. Normal operating conditions and installation conditions Ambient air humidity: upper limit value =60?, lower limit value =-10?(For the L/M/2M/2H controller, upper limit value = 70 ?, lower limit value = -10 ?),(For 3M/3H controller, 24-hour average value =+35?). Note: If the surro=2000m emperature exceeds Standard Value within the provisions working conditions, Users should consult with the factory. Elevation: The installation site elevation =2000m Atmospheric conditions: At the highest temperature is +40 ?, air relative humidity = 50%. At a lower temperature allows a higher relative humidity, for example, +20 ? and up to 90%, For the occasional temperature change produces moist must be taken special measures. Pollution Level: 3 Level Installation Type:the main circuit breaker and Under-voltage tripping coil, power transformer primary coil installation of category is ? , the remaining auxiliary circuit, control circuit installation of category is ?. Installation Conditions : Circuit breaker should be installed in accordance with the instructions of the installation requirements, circuit breakers, the vertical gradient of no more than 5 °. Installation Protection Level: IP30 (installed in the cabinet room and the installation of a small door to IP40). Use Category: B type Circuit Breaker Characteristics High Breaking Capacity, zero flashover distance, high security. Smart, better protection, and can interface with communication and achieve "remote control, telemetry, Remote Communication , Remote control to adjust ." Whole series of modular design , provide different electrical accessories, machinery accessories and intelligent controller unit, so that circuit breakers to meet different user needs. Compact structure, small size, the contact system is separated in a small room, high strength insulation, disjunction operation safe and reliable. With a wide choices: 3 pole or 4 pole, fixed or drawer-type and multi-controller type selected. Attached to communication interface, can connect with computer to achieve remote monitoring and management. Power can be motivated lines, can also be entered under the line, Ics unchanged
