Smart Reclosed RCBO

MT61SR

MT61SR is an integrated smart recloser RCBO with auto-recloser, residual current protection, overload protection, and over-voltage, and under-voltage protection. The device is reclosed after untimely tripping but only after an electrical circuit check.
• Voltage monitoring
• Remote control by RS485
• Dry Contact
• Data setting: Reclosing times, over/under voltage
• Current is up to 125A
