RCBO 是电气领域常见缩写,指 Residual Current Breaker with Overcurrent protection,中文常译为带过电流保护的剩余电流断路器(也可理解为“漏电保护 + 过载/短路保护二合一”的断路器)。它在检测到漏电(剩余电流)或过载/短路(过电流)时会自动断开电路。
/ˌɑːr siː biː ˈoʊ/
The electrician installed an RCBO to protect the kitchen circuit.
电工安装了一个 RCBO 来保护厨房回路。
Because the circuit runs outdoors, an RCBO is recommended to reduce shock risk and also protect against overloads.
由于该回路在户外使用,通常建议安装 RCBO,以降低触电风险,并同时提供过载保护。
RCBO 来自首字母缩略词:Residual Current Breaker with Overcurrent protection。它强调把两类保护功能(漏电保护与过电流保护)集成在同一设备中,常用于配电箱/配电盘内的支路保护。
