These fuse holders are supporters for fuses with size up to 22*58mm. They are capable of working under hear cased by rated current and expected short impacting current up to 100kA. It can also function as a fuse disconnecting switch by multi-phase combination. There are two in/out lines at the RT18N fuse base, providing a power cut function. The RT18L type has a safety lock to lock the fuse carrier when disconnected to avoid wrong operation; it can also be equipped with an indicator, which goes on when the fuse links breaks.Rated insulate voltage up to 690V; Working frequency 50Hz AC(DC); Conventional free air thermal current up to 125A;Compliant with GB13539.1, GB13539, GB13539.6, GB14048.3 and IEC60269-1, IEC60269-2, IEC60269-2-1, IEC947-3.
