Mersen 20326R – Frequently Asked Questions

1) Which Mersen part number do I order for a 1, 2, or 3 pole Class CC block?
Pole count is the ordering choice. Single pole is 20326R, two pole is 30322R, and three pole is 20328R. All three carry the same 600VAC/600VDC and 30A ratings, so pick purely on how many circuits you are fusing.
2) Can I use this Class CC fuse block on a 600V DC circuit, not just AC?
Both. The block is rated 600VAC and 600VDC, listed as AC/DC, with a 50/60 Hz frequency rating on the AC side. That makes it usable for DC control and power circuits up to 600V as well as standard 60 Hz branch circuits.
3) What is the difference between a Class CC block like this and a Class R or Class G block?
Fuse class is not interchangeable, and the block is built around the fuse body it holds. The Mersen 30322R takes Class CC (and 13/32 x 1-1/2 inch midget) fuses up to 30A at 600V. If your drawing calls for Class R, that is a physically different, larger fuse and you want something like the Littelfuse LFR60030-3CID Class R block, 600V 30A. For Class G, the Littelfuse LFG60015-1SQDINR is a 600V 15A Class G block on DIN rail. Match the class on the print, then the pole count.
4) Can I use the Mersen 30322R fuse block on a 1000 Vdc photovoltaic string circuit?
No. The Mersen 30322R is rated 600VAC/600VDC, so a 1000 Vdc PV array is above its voltage rating. For that application the Bussmann CHPV2 Series photovoltaic fuse block is a modular two-pole block rated 1000 Vdc. Keep the Mersen for 600V and below AC or DC branch circuit protection.
5) What is the closest Class CC equivalent to the Mersen 30322R two-pole fuse block from another manufacturer?
The Bussmann CHCC2DIU is the nearest peer: it is a 2-pole Class CC modular fuse block, matching the Mersen 30322R's two-pole Class CC configuration. The Bussmann unit is described as finger-safe with an indicator, while the Mersen block uses a clip-in fuse installation method with a glass-filled polycarbonate body and carries a 200 kA SCCR at 600VAC/600VDC. If the panel spec calls for finger-safe touch protection or blown-fuse indication, the CHCC2DIU addresses that; if the spec is a straight 30A Class CC clip block, the Mersen covers it.
6) What torque should the terminals be tightened to on the Mersen 30322R?
20 lb-in on the pressure-plate connectors. The connector accepts a wide range of stranded or solid copper wire, and hitting that torque figure is what keeps the connection low resistance under load.
7) I need more than 3 poles of Class CC fusing. Can I gang these blocks together?
Yes. The design uses an adder block that snaps onto any pole count, so you can build segmented multi-pole assemblies beyond the 3-pole unit rather than being capped at three circuits.
8) Is there a finger-safe Class CC fuse block alternative with a blown fuse indicator?
The Mersen 30322R is an open clip-in block without an indicator. If you need touch-safe terminals and a visual blown-fuse indication, the Bussmann CHCC2DIU is a 2-pole Class CC modular block that is finger-safe with an indicator. Same fuse class, so your Class CC fuse inventory still applies.
9) Is the Littelfuse LFG60015-1SQDINR a substitute for the Mersen 30322R Class CC fuse block?
No. The LFG60015-1SQDINR is a Class G fuse block rated 600V 15A for DIN rail mounting. The Mersen 30322R family is Class CC, rated 30A at 600VAC/600VDC. Different fuse class and a different current rating, so the two are not drop-in alternatives. Choose the Littelfuse when the design specifies Class G on DIN rail, and the Mersen when it specifies 30A Class CC.
10) I need more than three poles in one fuse block. What are my options versus the Mersen 30322R?
The Mersen Class CC family is offered in 1, 2, and 3 pole blocks, with an adder block design that snaps onto any pole count so multi-pole assemblies can be segmented and built up. If you would rather buy a single block with a higher native pole count, the Bussmann 3833 Series is offered in 1 to 8 pole configurations -- note that it is an AGC fuse block, so it takes a different fuse than the Mersen's Class CC clips.
11) What is the difference between a clip-in block like the Mersen 30322R and a bolt-in block?
The Mersen 30322R uses a clip-in fuse installation method -- the fuse pushes into reinforced tin-plated copper alloy clips, with a pressure-plate connector terminating stranded or solid copper wire at 20 lb-in. The Littelfuse LD Series POWR-BLOKS uses bolt-in mounting instead. Clip-in blocks let a technician change a fuse by hand without tooling the fuse itself; bolt-in styles are chosen where the design calls for a bolted termination.
12) Is the insulating body on this fuse block rated for a 600V industrial panel?
The body is glass filled polycarbonate with verified dielectric strength in excess of 2500V, well above the 600V circuit rating. The fuse clips are reinforced tin-plated copper alloy for a low-resistance hold on the fuse.
13) Is the Mersen 30322R RoHS compliant for our procurement spec?
Yes, RoHS compliant. That is the compliance statement carried on the block, and it applies across the 1, 2, and 3 pole versions.
14) Is the Bussmann BCM603 a direct swap for the Mersen 30322R two-pole block?
They are both two-pole modular fuse blocks, but they are not interchangeable without checking the fuse. The Bussmann BCM603 is from the BCM series; the Mersen 30322R takes 30A Class CC fuses and 30A midget fuses, is rated 600VAC/600VDC, and carries a 200 kA SCCR with a glass-filled polycarbonate body. Confirm the fuse class your panel drawing specifies before treating either as a substitute for the other.
