Bussmann C14M2 – Frequently Asked Questions

1) Is a gG/gL fuse the right class for motor circuits, or do I need aM?
Class gG/gL is a general-purpose characteristic: it protects against both overload and short circuit, which is what you want on cable, feeders and general distribution. The C10M1 is a gG/gL fuse. Motor circuits with high inrush are usually protected with an aM (motor-rated) fuse that ignores starting current and handles short circuit only, backed up by a separate overload relay. If your drawing calls out aM, gG/gL is not a substitute.
2) Can I use a 690V AC Bussmann C10M1 fuse on a 480V or 400V panel?
Yes. The 690V AC rating on the C10M1 is a maximum, so it can be applied at any lower system voltage, including 480V and 400V three phase. What you cannot do is go the other way, and you should not use it on DC, since it carries an AC rating only and its frequency window is 45 Hz to 62 Hz.
3) What amp ratings does the Bussmann C10M1 14x51mm cylindrical fuse come in?
Seventeen ratings, 1A through 125A: 1, 2, 4, 6, 8, 10, 12, 16, 20, 25, 32, 40, 50, 63, 80, 100 and 125 amps. Every one of them is the same 14 x 51 mm ferrule body, so you can standardize a panel on one holder type and stock the ratings your circuits actually call for.
4) What fault current can the Bussmann 14x51mm gG/gL fuse interrupt?
80 kA breaking capacity. That covers the available fault current at most commercial and industrial service and distribution points, so on a panel whose short circuit study lands under 80 kA the fuse clears without needing a supplementary current-limiting device ahead of it.
5) Does the Bussmann C10M1 fuse have a blown-fuse indicator?
No. The C10M1 is a non-indicating fuse, with no striker pin or visual flag on the end cap. Troubleshooting means pulling the carrier and metering the element, or using a holder with its own indication. If you are maintaining a panel where a tech needs to spot the open fuse at a glance, specify an indicating version of the 14 x 51 mm instead.
6) Does the Bussmann C10M1 meet IEC 60269 for a European-spec panel?
The C10M1 is built to IEC 60269, which is the standard cited for low voltage fuses on European and IEC-designed equipment. That is the compliance line to put on a submittal for gear specified to IEC rather than to a North American UL-fused design.
7) What is the part number for a 32A Bussmann 14x51mm gG/gL fuse?
The 32 amp rating in the 14 x 51 mm gG/gL range is Bussmann C22G32. The part number changes with the amp rating across the family, so ordering by amps alone is not enough: 10A is C14M10, 63A is C22M63, and 125A is C22M125. Match the number to the rating your circuit is sized for.
8) Will this Bussmann cylindrical fuse work on a 60 Hz North American system?
Yes. The rated frequency band runs 45 Hz to 62 Hz, which brackets both 60 Hz North American and 50 Hz systems. It is not rated for DC or for higher-frequency output such as the load side of a variable frequency drive.
9) Where is a 14x51mm ferrule fuse actually used on a job?
It goes in modular fused disconnects and fuse carriers on IEC-style panelboards and switchgear, protecting feeders, distribution blocks and control circuits. The gG/gL characteristic handles cable and general circuit overcurrent duty. The ferrule end x ferrule end body means there are no bolted lugs or blade terminals to torque, so replacement is a pull-and-drop in the carrier rather than a wired connection.
