Glass Fuse Time-Delay 3.20A 300V AC
This EATON BUSSMANN GMQ series glass fuse provides time-delay protection rated at 3.20 amps and 300 volts AC. It carries a 10kA interrupt rating at 300V AC and meets UL 248-14, CSA Class 1422-01 and CE standards. The cylindrical body measures 2-1/4 inches long by 5/8 inch diameter and fits compatible HLQ series fuse blocks.
Suits circuits needing time-delay overload tolerance
The time-delay characteristic helps absorb temporary inrush currents without nuisance opening, making it suitable for motor-start or transformer loads. Circuits that require fast-acting or very fast-acting response should select a different fuse type. Installations needing a higher voltage rating or a different physical size must choose another model.
Fits HLQ fuse blocks for secure mounting
The rejection-style design ensures correct insertion into HLQ series fuse blocks, reducing the risk of installing an incorrect fuse rating. No additional accessories or software are included with the fuse itself. The glass body allows visual inspection of the element after a fault event.

Questions about this item
Which fuse block series must I already have to install this GMQ fuse?
The compatible fuse block series is HLQ, so you need an HLQ-series block that accepts a 2-1/4 in by 5/8 in cylindrical glass fuse.
Will this 3.20 A time-delay fuse protect an older circuit rated for a lower interrupt capacity?
The fuse interrupts up to 10 kA at 300 V AC, which exceeds many legacy panels, so it will safely clear faults on older circuits within that voltage.
How can I verify the fuse is operating correctly once it is fitted?
With the circuit energised, measure voltage across the fuse; a reading near zero volts confirms the element is intact and carrying current.
