Fast acting distinguishes it from ATQ2

Ross Hill 0301-0010-00 uses Mersen's time-delay ATQ family. ATM30 is fast acting. The different response is not a minor naming change; it affects how the fuse reacts to transient current and fault conditions.

Supplemental is not branch protection

Mersen labels ATM30 as supplemental protection and not branch-circuit protection. Preserve that evaluated role. The 100 kA interrupting rating does not change the protection class or authorize a different use.
