Technical Parameters ■ Explosion-proof Mark: ExdeⅡBT6 *ExdeⅡCT6 ■ Rated Voltage: AC380/220V/50Hz ■ Main Circuit Current: ≤630A ■ Branch Circuit Current: ≤400A Product Features ■ Housing made of die-cast aluminum alloy with electrostatic powder coating; ■ Can select appropriate explosion-proof components based on the electrical schematic diagram and main technical parameters provided by the user, and design the dimensions of the distribution cabinet; ■ Panel layout can be customized according to user requirements, with options such as direct operation or operation after opening the door; ■ This product offers multiple solutions with various functions, which can be customized by the user based on actual needs. Common solution examples include: ① Multi-circuit power (lighting) distribution cabinet By combining multiple explosion-proof circuit breakers or power (lighting) distribution boxes with several explosion-proof junction boxes, this distribution cabinet enables power conversion, distribution, and control for lighting and power distribution equipment in a three-phase 50Hz power distribution system with a voltage of 380V and current of 630A. ② Multi-circuit electromagnetic starter distribution cabinet By combining multiple explosion-proof electromagnetic starters or electromagnetic starter boxes with explosion-proof circuit breakers, operation handles, and explosion-proof junction boxes, this distribution cabinet enables power distribution and centralized control of motors in a three-phase AC 50Hz power distribution system with a voltage of 380V. The maximum branch current can reach 160A. It can achieve remote control as per user requirements and can be equipped with signal lights, voltmeters, ammeters, and other monitoring devices as needed. ③ Multi-circuit reduced-voltage starter distribution cabinet By placing explosion-proof reduced-voltage starter boxes inside a protective cabinet, this distribution cabinet enables infrequent reduced-voltage starting for three-phase squirrel-cage motors with a capacity of 95KW or less in a 50Hz AC circuit with a voltage of 380V. It offers protection functions such as short-circuit, phase loss, overcurrent, and locked rotor protection, and can be controlled manually, automatically, or remotely. ④ Metering, monitoring, and control distribution cabinet By incorporating various explosion-proof meters or secondary instruments, this distribution cabinet enables the calculation and monitoring of various physical quantities in the circuit, such as parameters, pressure, and temperature. ⑤ Hybrid distribution cabinet Based on user requirements, corresponding explosion-proof electrical components are combined to meet on-site needs.
