The GL314 - GL318 live tank circuit breakers are for use in every kind of energy field including high-polluted environments and extreme climate conditions.
Based on our experience with the S1, HGF and FXT types of circuit breakers, the improved GL300 series is safer and more reliable. It offers a new generation spring operating mechanism and tie rod that enable quick and easy onsite installation.
