The amperage of a T2L 250v fuse is typically 8 amps. It is a misconception that it has an amperage of 3.
No. A T2AH fuse is a high-breaking capacity type whereas a T2L is low-breaking capacity. Often, High-breaking capacity fuses have ceramic (hence stronger) tubes and low-breaking capacity fuses have glass tubes. High-breaking capacity fuses are able to protect against higher short-circuit currents than low-breaking capacity ones (which could explode under the same conditions).
In order to answer that question, you need to give more information.
