What is a Type T plug fuse?
Type-TL and SL fuses are considered to be regular duty fuses. Type T and Type-S are heavy duty fuses for high inrush current applications and typically use a dual-element design. From a technical sense, plug fuse and circuit breakers are both capable of performing equivalent overcurrent protection.
What is the difference between Type-S and Type T fuses?
Type-S and Type-T Heavy-Duty Time-Delay Fuses However, just like the SL and TL fuses, the only difference between the S and the T heavy-duty fuses are the bases: type-S has a rejection base; type-T has an Edison base. Heavy-duty time-delay fuses contain a spring-loaded metal fuse link attached to a solder plug.

What is the difference between a class T fuse and ANL fuse?
An ANL fuse can interrupt up to 2700 amps. Perfect for an automotive starting battery that sees a dead short. Class T can interrupt up to 20,000 amps.
What are the classes of fuses?
UL Fuse Classification Chart
UL CLASS | FUSE OVERLOAD CHARACTERISTICS | INTERRUPTING RATING, AMPERES |
---|---|---|
CD | TIME-DELAY | 200,000 |
G | TIME-DELAY | 100,000 |
K5 | FAST-ACTING | 50,000 |
H | RENEWABLE FUSES FAST-ACTING | 10,000 |
What is the difference between AMG and ANL fuses?
ANL fuses have a higher AIC rating – 6000 amps. AMG fuses only have a 2000 amp AIC rating. That is the largest difference. It relates to battery bank size and the unique ability of a fuse with a low AIC rating to keep the circuit closed after blowing – in effect welding shut.

What is ANL fuse used for?
ANL fuses are used for general cable protection, providing a ‘medium blow’ (around 1 second) protection. These ANL fuses all feature fixing holes suitable for 5/16″ studs and range from 50 amps to 500 amps. Fuse holders designed for ANL fuses are also available.
