Description

Hyundai HiRC, HiRO and HiRD type residual current circuit breakers are mainly used to protect against earth leakage current under
the alternating current 50/60Hz, rated voltage AC240V or AC415V and with rated current 1 to 125A.
They open circuit automatically in the event an earth fault between phase and earth, or neutral and earth by detecting the residual
current and comparing with the rated residual current through ZCT.
HiRO and HiRD type, which are combinations of residual current device and miniature circuit breaker, also offer protection against
overload and short circuit as well as earth leakage. All products comply with IEC/EN standard, and can be applied to industry,
commerce, high-rise buildings, household and other similar installations
