SYTW3 智能型万能式断路器
Intelligent universal circuit breaker
特点 / Characteristics
智能控制器按功能分为二种类型:
L 型 - 电子型 ( 电流柱状显示、拔码调整 )
M 型 - 标准型 ( 电流数 ( 汉 ) 字显示、按钮或按键调整 )
H 型 - 通讯型 ( 电流数 ( 汉 ) 字显示、按钮或按键调整并可通讯 )
Intelligent controllers are divided into two types according to their functions:
L-type (current column display, dial adjustment)
M type - standard type (current number (Chinese) word display, button or button adjustment)
H type - communication type (current number (Han) word display, button or button adjustment and communication)
