Description

MAR-DU Current Monitoring Relays are designed to protect motors and systems against over current or under current with current adjustment and two delay adjustments for start-up and tripping. Start-up delay is provided to prevent a false alarm arising from initial motor start-up (demurrage) currents.
MAR-DU 电流检测继电器适用于电机或低压电力系统，防止过电流或低电流。继电器提供高、低电流设定旋钮及2个时间调整按钮（启动，报警）。启动时间是为防止电机启动时，高启动电流产生误动作而设计的。
