Plug Fuses

Littelfuse’s 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.

Littelfuse offers four types of plug fuses: TLO Series, TOO Series, SLO Series and SOO Series.

TLO Series

Littelfuse’s TLO Series are a medium time-delay Edison-base fuse. The National Electrical Code permits Edison base plug fuses to be used for replacement purposes only.

Amps (A): 15, 20, 25, 30

Vac (V): 125

Interrupting rating: 10kA rms symmetrical

Datasheet

TOO Series

The TOO Series dual-element time-delay Edison-base fuses. The National Electrical code permits Edison-base plug fuses to be used for replacement purposes. 

Amps (A): 0.3, 0.4, 0.5, 0.6, 0.8, 1, 1.125, 1.25, 1.4, 1.6, 1.8, 2, 2.25, 2.5, 2.8, 3, 3.2, 3.5, 4, 4.5, 5, 6, 6.25, 7, 8, 9, 10, 12, 14, 15, 20, 25, 30

Vac (V): 125

Interrupting rating: 10kA rms symmetrical

Datasheet

SLO Series

Littelfuse’s type S plug fuses (SOO and SLO series) utilise a non-metallic threaded base and must be used with Type S adapters SAO series). Type S fuses and adapters prevent shunting open fuses and over-fusing.

Amps (A): 15, 20, 25, 30

Vac (V): 125

Interrupting rating: 10kA rms symmetrical

Datasheet

SOO Series

The SOO Series is a dual-element time-delay Type S fuse. Type S fuses and adapters prevent shunting open fuses and over-fusing.

Amps (A): 0.25, 0.3, 0.4, 0.5, 0.6, 0.8, 1, 1.125, 1.25, 1.4, 1.6, 1.8, 2, 2.25, 2.5, 2.8, 3, 3.2, 3.5, 4, 5, 6, 6.25 7, 8, 9, 10, 12, 14, 15, 2.5, 2.8, 20, 25, 30

Vac (V): 125

Interrupting rating:10000A@125Vac
