Ross Hill 0301-0013-00 Fuse, ATQ10

Ross Hill 0301-0013-00 identifies the 10 A ATQ10 time-delay midget fuse, cataloged by Mersen as ATQ10. The exact item is rated 500 VAC at 50/60 Hz in a 10 x 38 mm ferrule format. Mersen classifies ATQ as a 500 VAC midget time-delay series for supplemental protection. The family data publishes a 12-second time delay at 200 percent rating and a 10 kA interrupting rating.

Part-number identification

ATQ10 fixes the manufacturer family, 10 A rating, time-delay characteristic, voltage class, and physical format. Match all of those fields with the fuse holder, protected load, and available fault current.

The complete installed label remains the ordering reference. Match the part number, electrical ratings, physical interface, and circuit duty before approving a replacement.

ATQ time delay protects control circuits through inrush

Control transformers, solenoids, and motor-control circuits can draw temporary inrush. The published ATQ delay prevents a permitted short-duration inrush from being treated like a sustained overcurrent. Coordination still depends on the actual load and equipment design.

Supplemental protection is the application boundary

Mersen states that ATQ10 is not for branch-circuit protection. Use it only where the equipment design calls for a supplemental midget fuse. A matching ampere and voltage marking does not authorize a different protection role.

The holder is part of the selection

The 10 x 38 mm (1-1/2 x 13/32 in.) cartridge must be checked with the installed holder. Confirm the holder catalog number, voltage rating, terminal condition, rejection or indication features, required approvals, and the circuit fault duty before returning it to service.

Ten amperes does not identify the time-current curve

A 10 A cartridge can be fast-acting, time-delay, branch-rated, or supplemental. ATQ10 specifically identifies the ATQ time-delay supplemental form. Preserve the complete catalog number so a general 10 A search does not substitute a different protection characteristic.
