Informasi Produk
Description
Stable protection characteristics by digital calculation High reliability by automatic monitoring (constant monitoring of internal circuits and automatic inspection of output circuits)
Driving support with multi-function display by LED display. Set value, measured value, elapsed time, error code Easy setting. Function setting by DIP switch, selection of set value by rotary knob Power failure compensation backup power supply is standard equipment. Operation lock can be controlled by both set knob and external control for each relay element.
Implemented OVGR output contact 2c
The OVGR output contact can be automatically restored / manually restored (self-holding). If manual recovery is selected, self-holding is continued even during a power failure. A simple UVR for power failure detection is implemented.
