Time delay is part of the selection

Mersen publishes ATQ as a midget time-delay family. That behavior can ride through a permitted temporary inrush that may open a fast-acting fuse. Replacing it by ampere rating alone can change circuit behavior even if the cartridge fits the holder.

Supplemental protection is a firm boundary

Mersen explicitly states that ATQ2 is not for branch-circuit protection. The application must preserve the role for which the equipment was evaluated. Do not move a fuse from an internal control circuit into a branch-protection role because voltage and ampere figures appear adequate.

FAQ

What is Ross Hill 0301-0010-00?
It is the RHCC number recorded in the GEN group as FUSE-FNQ 2 AMP, against the exact reference ATQ2.
What does Mersen publish for ATQ2?
Mersen specifies 2 A, 500 VAC, 50/60 Hz, time-delay operation, a 10 x 38 mm midget ferrule form, and a 10 kA interrupting rating.
Is ATQ2 suitable for branch-circuit protection?
Mersen explicitly classifies ATQ2 for supplemental protection and states that it is not for branch-circuit protection.
Can I select a replacement by 2 A alone?
No. Match family, time behavior, voltage, frequency, interrupting rating, dimensions, holder, protection role, approvals, and the protected load.
