Mersen GPM-G – Frequently Asked Questions
1) What voltage and amperage can the Mersen GPM-G fuse holder handle?
The GPM-G is rated 15 to 30 amps, 250 to 600 VAC, and up to 600 VDC. That AC/DC dual rating is what makes it usable in DC bus and drive circuits as well as standard 480V three-phase control panels. It is a single pole holder, so a three-phase circuit needs three of them.
2) Will the Mersen GPM-G meet the short circuit current rating on my control panel drawing?
The GPM-G carries a 100kA/200kA SCCR, which covers the 100kA series rating most industrial control panel specs call out. Pair it with a correctly sized current-limiting fuse, since the holder's rating only holds when the fuse in it is rated for the available fault current.
3) Is the Mersen GPM fuse holder UL listed or UL recognized?
It is a UL Recognized Component to Standard 4248-1 under File E52283, and CSA Certified under Class 6225, File 32169. Recognized, not Listed, means it is approved as a component inside an end product such as a control panel, which is how these holders are normally used. Inspectors looking for a standalone Listed device should know the difference before the panel gets submitted.
4) How does the GPM-G fuse holder mount, and does it go on DIN rail?
The GPM-G is a panel mount holder, so it fastens through the enclosure panel or subpanel rather than clipping to DIN rail. If your layout is built around a DIN rail assembly, you would need a DIN-mount holder instead.
5) Can I use one Mersen GPM-G to protect a three-phase motor circuit?
No. One GPM-G protects one pole. A three-phase feeder needs three holders, one per phase, each with its own fuse. For a 15 to 30 amp three-phase branch that means three GPM-G holders wired side by side in the panel.
6) For a 400A three-phase service feed, should I use the Mersen GPM-G or something else?
The Mersen GPM-G is not the right device for that duty. It is a single pole fuse holder rated 15 to 30 A, so it is sized for control circuits, instrumentation, and small branch loads inside an industrial or commercial panel. For a 400 A three-phase main lug application, the ABB MeterMod III 400A three-phase main lug panelboard is the class of product that fits. The GPM-G would still be used downstream inside a control enclosure fed from that distribution.
7) Is the Mersen GPM-G fuse holder body suitable for a damp or washdown industrial environment?
The body is thermoplastic polycarbonate and the contacts are tin-plated copper. Tin plating resists corrosion better than bare copper or brass in humid plant air, and polycarbonate handles the mechanical knocks of a working panel. Neither spec is an enclosure rating, so the environmental protection comes from the box you mount it in.
8) Is a Mersen GPM fuse holder the same thing as a panelboard for my distribution job?
No, and this is worth getting straight before ordering. The GPM-G is a single pole fuse holder for one circuit inside a panel. If you need a full distribution panelboard with a bus and multiple branch circuits, that is a different product entirely, such as the ABB ReliaGear Pro-Stock 42-circuit panelboard or the ABB MeterMod III 400A three-phase main lug panelboard. The GPM-G goes inside or alongside equipment like that, not in place of it.
9) Can an ABB ReliaGear Pro-Stock panelboard be used in place of a Mersen GPM-G fuse holder?
No, they do different jobs. The Mersen GPM-G is a single pole panel mount fuse holder that carries one fuse for overcurrent protection on a circuit, rated 15 to 30 A at 250 to 600 VAC and 600 VDC with a 100kA/200kA SCCR. The ABB ReliaGear Pro-Stock is a 42-circuit panelboard, an enclosure and bus assembly that distributes power to many branch circuits. If the job is protecting a single circuit or a control panel feed, the GPM-G is the device; the ReliaGear serves a distribution role and would not be ordered as a one-for-one replacement for a fuse holder.
10) What is the Mersen part number to order for the GPM panel mount fuse holder?
The model is GPM-G, Mersen's GPM Series single pole panel mount holder covering the 15 to 30 amp, 250 to 600 VAC range. That is the designation to quote or cross-reference at the counter.
11) What is the difference between the ABB MeterMod III and the ABB ReliaGear Pro-Stock when I already have Mersen GPM-G fuse holders in the control panel?
Both ABB units are distribution equipment feeding the panel, not replacements for the fuse holders. The MeterMod III is a 400 A three-phase main lug panelboard, while the ReliaGear Pro-Stock is a 42-circuit panelboard with copper bus at 240 V three-phase. The Mersen GPM-G fuse holders sit inside the control panel downstream of either one, each holding a single fuse for 15 to 30 A at 250 to 600 VAC or 600 VDC, so the choice of upstream panelboard does not change the fuse holder selection.
