Littelfuse Plug fuses provide overcurrent protection to general purpose circuits and small motor loads. Edison-base Plug fuses (TOO and TLO series) feature metal threads similar to incandescent lamp bases. Type S Plug fuses (SOO and SLO series) utilize a nonmetallic threaded base and must be used with Type S adapters (SAO series). The National Electrical Code permits Edison base Plug fuses to be used for replacement purposes only. Type S fuses and adapters prevent shunting open fuses and over-fusing.
- Features
- The national electric code now permits Edison base fuses to be used only for replacements in existing installations and then, only when there is no evidence of overfusing or tampering
- All new Edison-based fuse holders must have type S fuse adapters installed before they are placed in service
- Designed to prevent installation of wrong size fuses, Type S adapters (SAO series) screw into Edison base fuse holders so they may accept Type S fuses
- Once installed the adapters cannot be removed
- To prevent shunting of open fuses or over-fusing and to reduce nuisance fuse opening, it is recommended that SAO adapters with properly rated SOO series fuses be installed in all Edison base fuse holders
- 10 kA (rms symmetrical) interrupt rating
