Ross Hill 0301-0009-00 identifies a 0.6 A, 500 V time-delay midget fuse; confirm the exact ATQ or FNQ family marking and installed holder before ordering. Use the complete installed identifiers and equipment ratings as the ordering reference. Availability, condition, price, and lead time are confirmed for each request.

The trap, in both numbering systems at once

A control circuit protected by a 6 A fuse where 0.6 A was intended is protected by very little. The failure is not immediate and not obvious, which is what makes it worth a page.

The whole fuse block on this equipment

Five fuses in the 0301 block share a family and a voltage and differ only in rating.

Two things are worth noticing. The 3.5 A row uses a decimal point in the reference the same way the 0.6 A row does, so the punctuation is doing real work throughout. And the block spans two system groups, so a store that files by group will have these five in two places.

What is worth knowing is that the FNQ family has a rejection-style variant, FNQ-R, and rejection-style fuses and holders exist specifically so that the wrong fuse will not go in. We did not establish which holders this equipment uses, so we are not telling you whether an FNQ and an FNQ-R will interchange in your panel. Send us the holder and we will treat it as a real question rather than a guess.

What to send with your request

The printing on the fuse body settles this one in about ten seconds.

• The complete printing on the fuse body, read character by character including any slash or decimal point
• A photograph of the fuse and, if you can, of the holder it came out of
• Whether the circuit is control, indication, or something else, if you know
• Quantity required, remembering that these are usually held in tens
• The condition you can accept and your need-by date

We do not need a purchase order to answer an identification question. Send the number and the photograph and we will tell you what we can establish.
