Residual Current Breaker
with Overcurrent Protection
Why UNION RCBOs?
Residual Current Circuit Breaker with Over Current Protection (RCBOs) are commonly used in applications where there is the need to combine protection against overcurrents (overload and short-circuit) and protection against earth leakage currents. RCBOs are basically combination and adjustment of MCB and RCCB.
Union RCBOs are CE, CCC certified by independent instuties in China, Europe and USA. Electronic and magnetic trip unit options are available from 10mA to 300mA leakage current sensitivity with adjustable options.
