Mersen P292 – Frequently Asked Questions

1) Does the Mersen P292 mount on DIN rail?
No. The P292 P-Block is a direct screw mount block, so it fastens to the panel or subplate with screws through the block body. For a DIN rail installation you would need a rail-mount block such as the Littelfuse LFG60015-1SQDINR, which is a 600V 15A Class G DIN rail block.
2) I need three-phase protection. How many of these Mersen P-Block fuse blocks do I order?
The P292 is a 1-pole block, so a three-phase circuit takes three of them mounted side by side on the panel. If you want a single multi-pole assembly instead, two-pole modular blocks like the Bussmann BCM603 Series or the Bussmann CHCC2DIU exist, though those are different fuse classes and lower voltage families.
3) What is the closest alternative to the Mersen P292 fuse block if I need another bolt-in style fuse block?
The Mersen P292 P-Block uses a bolt-in fuse installation method with clip-style tin-plated copper terminals and a phenolic insulator body. The nearest alternative in the same mounting style is the Littelfuse LD Series POWR-BLOKS fuse block, which is also a bolt-in mounting fuse block. Confirm the fuse form and voltage class your fuse requires before swapping, since the P292 is built for semiconductor fuses rated 1200V AC and 1200V DC (UL) at 30A.
4) Can I DIN rail mount the Mersen P292 fuse block?
No. The Mersen P292 is a direct screw mount block, so it fastens to a panel or subplate rather than snapping to rail. If your enclosure is laid out for DIN rail, the Littelfuse LFG60015-1SQDINR is a Class G fuse block rated 600V 15A with DIN rail mounting. It is a different fuse class and a lower voltage and amperage than the P292's 1200V AC/DC 30A semiconductor rating, so it is a layout alternative rather than an electrical equivalent.
5) Is the Bussmann CHPV2 photovoltaic fuse block a substitute for the Mersen P292 on a DC solar circuit?
They are not interchangeable. The Bussmann CHPV2 Series is a modular two-pole photovoltaic fuse block rated 1000 Vdc, intended for PV string protection. The Mersen P292 is a 1-pole block rated 1200V DC (UL) and 1200V AC built for bolt-in semiconductor fuses on direct screw mounting. If your drawing calls for a PV-specific modular block with two poles, the CHPV2 is the one to specify; if it calls for a bolt-in semiconductor fuse at 1200V, the P292 is.
6) I only need a 600V 30A fused disconnect point in a control panel, not 1200V. What should I use instead of the Mersen P292?
The Mersen P292 is rated 1200V AC and 1200V DC (UL) at 30A for semiconductor fuses, which is more voltage class than a standard 600V control circuit needs. For a 600V 30A application, the Littelfuse LFR60030-3CID is a Class R fuse block rated 600V 30A. Note that it is a three-pole block, while the P292 is 1-pole, so size your panel space and circuit count accordingly.
7) Is a 10 kA SCCR enough for my industrial panel?
The P292 is rated 10 kA short circuit current, which has to be equal to or greater than the available fault current at the point of installation. If your panel's available fault current exceeds 10 kA at that location, this block cannot be used there as-is. On the fuse side it will take semiconductor fuses up to 30 A maximum.
8) What else sells as a bolt-in fuse block if the Mersen P-Block does not fit my layout?
The Littelfuse LD Series POWR-BLOKS is the other bolt-in mounting fuse block family we carry, so it is the closest alternative on mounting style. The Mersen P292 itself is the 1200V AC/DC, 30A, 1-pole option with a 10 kA SCCR and a phenolic body.
9) I need a finger-safe fuse block with blown-fuse indication. Does the Mersen P292 offer that?
The Mersen P292 is an open-style block with clip terminals and a phenolic insulator body, specified by its 1200V AC/DC and 30A semiconductor fuse ratings rather than by touch-safe features. If finger-safe construction and a blown-fuse indicator are what you need, the Bussmann CHCC2DIU is a 2-pole Class CC modular fuse block that is finger-safe with an indicator. It takes Class CC fuses, not the bolt-in semiconductor fuses the P292 is built around.
10) Will a Bussmann 3833 Series AGC fuse block work in place of the Mersen P292?
No. The Bussmann 3833 Series is an AGC fuse block offered in 1 to 8-pole configurations, built for small glass-tube AGC fuses typical of low-voltage control and automotive-style circuits. The Mersen P292 is a 1-pole block for bolt-in semiconductor fuses rated 1200V AC and 1200V DC (UL) at 30A with a 10 kA short-circuit current rating. The fuse bodies are not compatible and the voltage classes are not comparable.
11) If I need two poles rather than one, what can I use instead of the Mersen P292?
The Mersen P292 is a 1-pole block, so a two-pole circuit means either two blocks or a multi-pole alternative. Bussmann offers the BCM603 Series two-pole modular fuse block and the CHCC2DIU 2-pole Class CC modular block. Both are different fuse classes from the P292's bolt-in semiconductor fuse, so match the block to the fuse your circuit is protecting rather than to pole count alone.
12) What is the Mersen P292 block body made of, and will it hold up in a hot enclosure?
The insulator body is phenolic, a thermoset laminate that resists heat and mechanical stress, which is why these blocks are used in semiconductor fuse and drive protection duty where the fuse runs warm. The connection clips are tin-plated copper for low resistance contact, and the studs, clips and mounting hardware are tin or zinc plated against corrosion.
13) Is the Mersen P-Block P292 RoHS compliant for a spec job?
Yes, the P292 is RoHS compliant. The Mersen part number to put on the submittal is P292, a 1-pole 1200V AC/DC, 30A semiconductor fuse block.
