Mersen CEP-FS30CC1 – Frequently Asked Questions

1) Will the Mersen CEP-FS30CC1 fusible switch take Class J or Midget fuses, or only Class CC?
Class CC only. The CEP-FS30CC1 is built around the Class CC fuse body, with a maximum fuse rating of 30 A, so a Class J or a standard midget fuse will not seat correctly. Size the fuse at or below 30 A for the circuit you are protecting.
2) Can I use this 30A fusible switch on a 480V circuit?
No. The UL voltage rating on the CEP-FS30CC1 tops out at 347 VAC (and 125 VDC), so a 480 V circuit is outside its listed rating. It suits 347 V line-to-neutral single-phase loads common on 600/347 V systems, or DC control circuits up to 125 V.
3) How does the Mersen CEP-FS30CC1 mount in a control panel, and how much rail space does it eat?
It snaps onto standard DIN rail, no panel drilling or separate bracket. The body is 0.69 in wide, so a single pole occupies well under an inch of rail run, and it stands 3.4 in high by 3.65 in long. Plan gutter depth around that 3.65 in dimension before you lay out the subpanel.
4) What wire sizes will the terminals on this Mersen fusible switch accept?
Box-type terminals take #4 through #18 AWG, which covers everything from a small control conductor up to the feeder size you would realistically land on a 30 A single-pole circuit. The terminals are zinc-plated steel, so they hold up in damp or lightly corrosive panel environments.
5) I need to switch all three phases. Is one CEP-FS30CC1 enough?
No. It is a 1-pole device, so it opens a single conductor. For a two or three phase disconnect you need the matching multi-pole version of the CEP fusible switch, or gang the appropriate number of poles. Ordering a single unit for a 3-phase motor circuit leaves two legs live.
6) Is this a disconnect switch or just a fuse holder?
Both functions in one device. The CEP-FS30CC1 is a UL 98 fusible switch, meaning it provides a switching mechanism to open the circuit for service plus the Class CC fuse carrier for overcurrent protection. A plain fuse holder gives you the fuse only and is not a load-break disconnect.
7) Is the Mersen CEP-FS30CC1 RoHS compliant for a spec that requires it?
Yes, it is RoHS compliant, which matters on OEM equipment and institutional projects where the submittal package calls for it. Order by the manufacturer part number CEP-FS30CC1.
