Bussmann BH-3003 – Frequently Asked Questions
1) I need to replace a Bussmann fuse block marked BH-3003 - is this the same part?
Yes. Bussmann's BH-3003 is sold as a direct-reference replacement for installations already specifying that model, and the manufacturer part number on it is BH-3003. If the block in the gear carries that stamp, order by that number and you are matching it one for one.
2) What else does ZenSupply carry if I need a Class R or Class G fuse block instead of the Bussmann BH-3003?
For a Class R application, the Littelfuse LFR60030-3CID is a three-pole Class R block rated 600V 30A. For Class G, the Littelfuse LFG60015-1SQDINR is a 600V 15A Class G block that mounts on DIN rail, which matters if your enclosure is rail-based rather than panel-drilled. Fuse class is not interchangeable, so match the block to the fuse class your overcurrent protection scheme calls for.
3) What is an alternative to the Bussmann BH-3003 fuse block if the panel needs a Class R block rated 600V 30A?
The Bussmann BH-3003 is a fuse block for holding and connecting fuses in circuit protection equipment, ordered by its BH-3003 model number. If the circuit calls specifically for a Class R block at 600V 30A, the Littelfuse LFR60030-3CID Class R Fuse Block is built to that rating in the LFR Series. Class R blocks are dimensioned for Class R fuses and include the rejection feature that prevents a lower-interrupting-rating fuse from being installed, so confirm the fuse class your drawing specifies before choosing between them.
4) Is there a DIN rail mount fuse block option instead of the Bussmann BH-3003?
The Bussmann BH-3003 is identified for ordering by its model number, and the manufacturer specification sheet is the place to confirm its mounting arrangement. Where a control panel is laid out on DIN rail, the Littelfuse LFG60015-1SQDINR is a Class G fuse block rated 600V 15A with DIN rail mounting in the LFG Series. Class G fuses are a smaller, lower-amperage body than general purpose blocks handle, so match the block to the fuse class and amperage already on the circuit rather than to the mounting style alone.
5) What is the Bussmann BH-3003 and what does it do in a circuit?
The BH-3003 is a Bussmann fuse block, the component that holds a fuse and ties it into the circuit it protects. It is used in panelboards, disconnects, and distribution equipment where a fuse-protected circuit has to be completed or a damaged block swapped out. The part is ordered by the model number BH-3003.
6) Does the BH-3003 come in more than one configuration or amp rating?
No. The BH-3003 is a single-model item, with one orderable configuration under that part number. There are no finish, amperage, or mounting variations to pick from, so the only thing to confirm before ordering is that your gear calls for BH-3003 specifically.
7) I need a bolt-in mounted fuse block for a switchboard - is there an alternative to the Bussmann block?
The Littelfuse LD Series POWR-BLOKS fuse block uses bolt-in mounting, which is what you want where the block is fastened directly to a pan or panel rather than clipped to rail. Bolt-in versus DIN rail is a mechanical decision made by the enclosure, so check how the existing block is fixed before you choose.
8) What fuse block should I look at if the block has to be bolted into switchgear rather than snapped onto rail?
For a bolt-in mounting arrangement, the Littelfuse LD Series POWR-BLOKS fuse block is specified for bolt-in mounting, which suits blocks landed directly onto a panel or switchgear backplate. The Bussmann BH-3003 is a fuse block for panelboards, disconnects, and distribution equipment and is ordered by its BH-3003 model number; check its manufacturer specification sheet against your mounting hole pattern before substituting either way.
9) Can a Littelfuse Class G block be used in place of a Bussmann BH-3003 if the amperage matches?
Not on amperage alone. The Littelfuse LFG60015-1SQDINR is a Class G block, and Class G blocks accept only Class G fuse bodies - a different physical size and rejection profile from other fuse classes. The Bussmann BH-3003 should be matched by its own model number when replacing an existing BH-3003, since specifying the exact model is what avoids ordering the wrong part for the circuit. Treat fuse class, not current rating, as the first filter when cross-shopping blocks.
10) Is the Bussmann BH-3003 a genuine OEM part or an aftermarket equivalent?
It is a genuine Bussmann component, not a look-alike. That matters on renovation and maintenance work where the original gear was built around Bussmann blocks and the inspector or the spec calls for the manufacturer's own part.
