3 Phase Over Under Voltage Protector With Overcurrent Protection
General
The RCB-02 series is a microcontroller-based transfer solution designed
for reliable power management. It ofers a wide range of features, includ-
ing a “Priority” phase selection, overoltage and underoltage protection, overcurrent protection, parameter setting via knobs, LED indication for
operating voltage, and Din-rail mounting. This series is widely applicable
across residential, commercial, and industrial environments.
