Mersen 60608R – Frequently Asked Questions

1) Can I use the Mersen 60608R on a 480V three-phase motor circuit?
Yes. The 60608R is a 3-pole block rated 600VAC/600VDC, so a 480V three-phase feeder or motor branch circuit is well inside its rating. Its 60A rating sets the ceiling on the fuse you can install. Common uses are motor control centers, distribution panels, and HVAC circuit protection.
2) Can I use a Class G fuse block instead of the Mersen 60608R?
No, they are not interchangeable. The Mersen 60608R is built for Class R fuses, which have a rejection feature and a body dimension specific to that class, and it is rated 60A. The Littelfuse LFG60015-1SQDINR is a Class G block rated 600V 15A. Class G fuses are physically smaller and the ampere ceiling is far lower, so a Class G block will not accept the Class R fuses your drawing calls out. Match the block to the fuse class specified on the print.
3) What is the closest Class R fuse block alternative to the Mersen 60608R for a 600V circuit?
The Littelfuse LFR60030-3CID is the nearest Class R equivalent. Both are Class R blocks rated for 600V service, and both are three-pole, so either will carry a three-phase branch. The difference is ampere rating: the Mersen 60608R is a 60A block, while the LFR60030-3CID is rated 30A. If the fuses in the opening are 35A or larger, the 60608R is the one that accepts them; for circuits fused at 30A or below, the Littelfuse block is sized for it. The 60608R also carries a 600VDC rating alongside 600VAC, which matters on DC drives and battery circuits.
4) Is the Mersen 60608R the right fuse block for a solar PV array?
For a photovoltaic string the Bussmann CHPV2 Series block is the purpose-built choice - it is a modular two-pole photovoltaic fuse block rated 1000 Vdc, which covers the higher string voltages typical of PV. The Mersen 60608R is rated 600VAC/600VDC in a three-pole arrangement, so it suits DC circuits at or below 600V but not a 1000 Vdc array. On the AC side of the system, or on 600V DC equipment, the 60608R applies.
5) Is the Mersen 60608R fuse block rated for DC, like a battery or drive circuit?
It carries a dual rating of 600VAC and 600VDC, so it is usable on DC systems up to 600 volts as well as AC. Make sure the fuse you install is also DC rated at your system voltage; the block rating does not carry the fuse.
6) What short circuit current rating does the Mersen 60608R fuse block have?
200 kA SCCR when used with Class R fuses. That matters on a panel SCCR calculation: if your available fault current at the service is 65 kA or 100 kA, this block with properly rated Class R fuses does not become the limiting component in the assembly.
7) I need a Class R block but only 30 amps. What else is there besides the Mersen 60608R?
The Mersen 60608R is a 60A 3-pole Class R block. For a smaller circuit, the Littelfuse LFR60030-3CID is a Class R block rated 600V 30A, also three pole. Pick by the fuse amp rating your branch circuit calls for, not by the load, since the block sets the maximum fuse size it will hold.
8) What is the difference between the clip-in Mersen 60608R and a bolt-in fuse block?
The Mersen 60608R uses a reinforced clip-in fuse installation, so the fuse pushes into spring clips and can be pulled and replaced by hand during maintenance. The Littelfuse LD Series POWR-BLOKS is a bolt-in mounting block, where the fuse is fastened down with hardware. Clip-in favors fast fuse changes in motor control centers and distribution panels; bolt-in favors installations where the connection is set once and not disturbed. Choose based on how often the fuse is expected to be serviced and what the panel layout allows.
9) I need a fuse block that mounts on DIN rail instead of screwing to the panel - what should I order?
The Mersen 60608R is a direct screw mount block that fastens to the panel or subpanel surface. If the enclosure is built around DIN rail, the Littelfuse LFG60015-1SQDINR is a DIN rail mount block, though it is a Class G device rated 600V 15A rather than Class R at 60A. That means the DIN rail option is only a substitute if the circuit is small enough and the fuse class can change; on a 60A Class R feeder, plan on screw-mounting the 60608R.
10) Which fuse block should I standardize on across a facility with mixed 30A and 60A Class R circuits?
Two Class R blocks cover that range: the Mersen 60608R at 60A, three-pole, 600VAC/600VDC, and the Littelfuse LFR60030-3CID at 600V 30A. Both are Class R, so the fuse class and the rejection feature stay consistent across the plant and your fuse stock stays simple. Stocking the 60608R for feeders and motor circuits at 35A to 60A and the 30A Littelfuse block for smaller branches keeps you on one fuse class facility-wide while sizing each block to its circuit.
11) What is the body of the Mersen 60608R fuse block made of?
Glass filled polycarbonate. That gives it mechanical strength and thermal stability for enclosure mounting where the block sees heat from the fuses and vibration from nearby contactors. The block is also RoHS compliant, which matters on export machinery builds.
