第三部分：产品详细说明
[型号]+产品概述
这玩意儿是Cutler-Hammer FDB系列的“配电铁闸门”。为啥工程师都选它？因为它能扛住数据中心和工厂配电柜的“电流洪流”——300A三相稳供，400V电压直通，电机过载直接跳闸，烧毁风险清零。老工程师最看重的两点：省心（IP65防水防尘，暴雨/沙尘暴环境零故障）、稳定（抗爆震设计，机房/车间连续运行寿命比普通断路器长2倍）。
核心参数解析
额定电流：300A（驱动200kW电机无压力）。
电压等级：400V AC（适配中高压工业场景，省去变压器降压烦恼）。
分断能力：40kA（短路电流瞬间切断，设备保护零延迟）。

Part 3:Product details
[Model]+Product Overview
This thing is the”distribution iron gate”of the Cutler-Hammer FDB series.Why do engineers choose it?Because it can withstand the”current torrent”of data centers and factory distribution cabinets-300A three-phase stable supply,400V voltage is straight through,the motor is directly tripped overload,and the risk of burning is cleared.Two of the most important points of old engineers:worry-free(IP65 waterproof and dustproof,zero fault in heavy rain/sandror storm environment),stability(detonation-resistant design,continuous operation life of the computer room/workshop is twice as long as that of ordinary circuit breakers).
Core parameter analysis
Rated current:300A(drive 200kW motor without pressure).
Voltage level:400V AC(adapted to medium and high voltage industrial scenarios,eliminating the trouble of transformer step-down).
Breakout capacity:40kA(short circuit current is instantly cut off,equipment protection zero delay).
