Function
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 RT-18L 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.

Feature
1.After the plastic-injected case is equipped with contacts and fuse links, the bases are forms by welding or riveting both capable of being multi-phase structured.
2.RT19 are open-structure, and others are semi-concealed structure.
3.There are five fuse sizes available to choose from for the same fuse base of RT18N,RT18B, RT18C.
4.There are two sets of in-out lines for RT-18N.One is installed with fuse links of the according size.The other is a permanent open contacts with double breaking points. The whole base unit can cut the power.
5.RT18 bases are all DIN rail installed, among which the RT18L in equipped with safety lock against wrong operation in the breaking state.
