Mersen USCC1 – Frequently Asked Questions

1) What size fuses does the Mersen USCC1 fuse holder take?
The USCC1 accepts Class CC fuses up to 30 A. Class CC is a 13/32 x 1-1/2 inch rejection-style fuse, so only Class CC fuses will seat in the clips, which is the point of the holder: it keeps someone from dropping in a non-current-limiting fuse. Fuses are clip-in, so replacement needs no tools.
2) Can I use the Mersen USCC1 on a 600V DC solar or battery circuit, or is it AC only?
It's rated 600 V on both sides: 600 VAC and 600 VDC, UL rated, marked AC/DC. That's why it turns up in PV combiner and DC control work as well as standard 50/60 Hz AC panels. The DC rating applies to the holder; the fuse you install has to carry its own DC rating at your voltage.
3) What wire size and torque do the terminals on the Mersen USCC1 take?
Copper conductors from #14 up to #6 AWG, tightened to 15 lb-in. Use a torque screwdriver on it, since loose terminals on a fused branch are the usual cause of heating at the holder. Copper only, per the wiring range.
4) Will the Mersen USCC1 hold up on a panel with a 200 kA available fault current?
Yes. The holder carries a 200 kA short circuit current rating, which is what lets a panel builder claim a high SCCR on the assembly when it's fused with current-limiting Class CC fuses. The body is glass filled polycarbonate, chosen for dielectric strength and mechanical hold-up at fault.
5) Can a Littelfuse WPB1 in-line watertight fuse holder be used in place of the Mersen USCC1 in a control panel?
No, they solve different problems. The Mersen USCC1 is a Class CC fuse holder that clips onto DIN rail inside a panel, takes 1-pole Class CC fuses up to 30 A, and is rated 600 VAC/600 VDC with a 200 kA short circuit current rating. The Littelfuse WPB1 is an in-line watertight fuse holder, meaning it is spliced into a cable run rather than mounted on rail inside an enclosure. If you are landing Cu #6-14 conductors at 15 lb-in inside a control panel or motor control center, the USCC1 is the DIN rail device; the WPB1 addresses an exposed or wet in-line splice instead.
6) Is a Littelfuse LSRY plug fuse box cover unit an alternative to the Mersen USCC1 Class CC holder?
They are not interchangeable. The Littelfuse LSRY series is a plug fuse box cover unit rated 125 V, 15 A, which uses screw-in plug fuses at a box cover. The Mersen USCC1 accepts clip-in Class CC fuses, is rated 600 VAC and 600 VDC at 30 A, and mounts on DIN rail. For a 600 V industrial control panel or a DC solar circuit, the USCC1 is the applicable device; the LSRY addresses low-voltage plug fuse work at a box cover.
7) I need a fuse holder for a wet outdoor location, not a control panel. Is the USCC1 the right one?
No. The USCC1 is a DIN rail holder for enclosed panels, with no weather protection of its own. For a wet or exposed run, look at the Littelfuse WPB1 Series in-line watertight fuse holder instead, which is built to be spliced into the cable rather than mounted on rail.
8) Can the Mersen USCC1 replace a plug fuse box cover unit on a 125V circuit?
Different animal. The USCC1 is a 600 V, 30 A Class CC holder for DIN rail inside an industrial panel. A residential-style plug fuse application is served by something like the Littelfuse LSRY Series plug fuse box cover unit, rated 125V 15A. Don't cross them.
9) I need fuse protection on a wet outdoor cable run, not inside a panel. What should I use instead of the Mersen USCC1?
The USCC1 is a glass filled polycarbonate DIN rail device intended for mounting inside industrial control panels and distribution enclosures, so it depends on the enclosure for environmental protection. For a fuse placed directly in an exposed cable run, the Littelfuse WPB1 series is an in-line watertight fuse holder built for that position. Keep the USCC1 for the panel side of the circuit where Class CC current limiting at 600 V is required.
10) Is the Mersen USCC1 RoHS compliant for an export control panel?
It is RoHS compliant, which is usually what a machine builder shipping into the EU needs on the bill of materials for the fuse holder line item.
