Does this work as a class T Fuse?

I believe the DC IR 20kA rating is the same as a Class T fuse with a 20,000 AIC rating.

I would not trust that a product from ebay is legit.

The "AG" in the code on the label deciphered means: A = Partial-range breaking capacity (short-circuit protection only)
G = General purpose applications. General purpose fuses are not "very fast blow" like class-t. They are only "fast blow".

A proper battery fuse would have the 1st letter "G" meaning Full-range breaking capacity (overload and short-circuit protection)
The 2nd letter should be an "S" meaning lower power dissipation due to tighter melting gate values. The lower power dissipation in class gS fuses also result in lower fuse body temperatures. Typical applications include protection of battery systems, semiconductors (diodes, thyristors, triacs, etc) used in power rectifiers, UPS, converters, motor drives, soft starters, solid state relays, photovoltaic inverters, welding inverters and any application where it is necessary to protect semiconductor devices.

In other words No, they won't.

What about this one:
Will it have the same Breaking Amps as a T Class fuse?

Class-T would be perfect. Most of the rest is probably close enough.
What equipment is this getting connected to? Is 400 the correct amp rating you need?

Why would anyone NOT buy somthing meant to save your life or property from a certified dealer…

Ebay can have deals on somthings , fun stuff…fluff stuff… I would be cautious about stuff you must depend on..
