Bussmann BG3012SQ SC-Class Fuse Block Holder

The Bussmann BG3012SQ is an SC-Class fuse block engineered to securely mount and protect SC-series (rejection-style) fuses within electrical panels, control cabinets, and switchboards. As part of the Bussmann fuse block lineup, this SC fuse block gives electricians, panel builders, and maintenance teams a dependable mounting platform for branch-circuit and equipment overcurrent protection. Because it is built specifically for the SC fuse class, the BG3012SQ helps ensure that only the correct rejection-style fuse can be installed in the holder. The BG3012SQ model number allows for quick identification and cross-reference when specifying, ordering, or replacing fuse holders in an existing installation.

Key Features

  • SC-Class Fuse Compatibility: Designed to accept SC-series (rejection-style) fuses, helping ensure the correct fuse type is installed for the intended application.
  • Secure Mounting Platform: The fuse block provides a stable, panel-mountable base that holds the SC fuse firmly in place during operation.
  • Bussmann BG3012SQ Identification: Marked with the Bussmann BG3012SQ part designation for accurate specification, ordering, and replacement.
  • Maintenance-Friendly Access: Block construction is intended to allow straightforward fuse insertion and removal when service or fuse replacement is required.
  • Compact Fuse Holder Format: Sized to fit standard fuse-block mounting arrangements commonly used in industrial and commercial electrical enclosures.
  • Rejection-Style Fuse Support: Supports the rejection-style feature of SC-Class fuses, which is intended to help prevent installation of an incorrect fuse type in the holder.
  • Panel and Enclosure Ready: Suited for mounting within typical panel and enclosure layouts where SC fuse blocks are commonly installed.

Bussmann BG3012SQ – Frequently Asked Questions

1) What fuses does the Bussmann BG3012SQ fuse block accept?
The BG3012SQ is built for SC-series (rejection-style) fuses only. The rejection feature means a non-SC fuse will not seat in the block, so you cannot accidentally drop in a different class. If the fuses on hand are Class R, Class G, or Class J, this is the wrong block.
2) I'm replacing an old SC fuse block in an existing panel - will the Bussmann BG3012SQ work?
Replacement of existing SC fuse blocks is one of the listed uses for the BG3012SQ, and it fits standard fuse-block mounting arrangements used in industrial and commercial enclosures. Pull the old block and match the SC fuse size and the amp rating stamped on it before you order, since SC blocks are built per fuse size.
3) My drawing calls for a Class R or Class G fuse block, not SC - what should I use instead?
The BG3012SQ will not take those fuses. For Class R, the Littelfuse LFR60030-3CID is a 600V 30A three-pole Class R block. For Class G, the Littelfuse LFG60015-1SQDINR is a 600V 15A single-pole block that snaps onto DIN rail, which is handy if your cabinet is already railed out rather than drilled for screw mounting.
4) If the panel uses Class R fuses instead of SC fuses, what fuse block should be used in place of the Bussmann BG3012SQ?
The Bussmann BG3012SQ is built specifically for SC-series rejection-style fuses, so it will not seat a Class R fuse. For a Class R opening, the Littelfuse LFR60030-3CID is a Class R fuse block rated 600V 30A. Class R and SC fuses use different rejection geometry, so the block has to match the fuse class already specified on the drawing.
5) What is the DIN rail alternative if the enclosure has no room for a panel-mounted SC fuse block?
The Bussmann BG3012SQ mounts as a panel-mountable base inside panels, control cabinets, and switchboards. Where the enclosure is laid out around DIN rail, the Littelfuse LFG60015-1SQDINR is a Class G fuse block rated 600V 15A with DIN rail mounting. Note that it takes Class G fuses rather than SC-series, so the fuse itself changes along with the mounting method.
6) Do I need a bolt-in fuse block for a high-current feeder instead of an SC block?
For heavy feeder work, a bolt-in block is the usual answer, and the Littelfuse LD Series POWR-BLOKS block uses bolt-in mounting. The Bussmann BG3012SQ is a compact SC-Class holder aimed at branch-circuit and equipment-level protection inside panels and control gear, not large feeder duty.
7) We are standardizing a motor control center on one fuse block. How do the SC, Class G, and Class R options differ?
The Bussmann BG3012SQ covers SC-series rejection-style fuses for branch-circuit and equipment protection in panels, motor control centers, and switchboards. The Littelfuse LFG60015-1SQDINR covers Class G at 600V 15A on DIN rail, and the Littelfuse LFR60030-3CID covers Class R at 600V 30A. Because each block only accepts its own fuse class, standardizing means picking the fuse class first and then the block, not the reverse.
8) Is the Littelfuse POWR-BLOKS LD Series a direct replacement for a Bussmann BG3012SQ?
No. The Littelfuse LD Series POWR-BLOKS is a bolt-in mounting fuse block, while the Bussmann BG3012SQ is an SC-Class block sized for standard fuse-block mounting arrangements and dedicated to SC rejection-style fuses. Treat the LD Series as a different mounting and fuse-class decision rather than a drop-in swap for an existing BG3012SQ hole pattern.
9) What is the part number I should order for a Bussmann SC-Class fuse block?
Order by the Bussmann part designation BG3012SQ. That is the marking on the block itself, which is what you cross-reference when specifying or matching an installed holder.
10) Can maintenance staff change the fuse without pulling the block out of the panel?
Yes, the block is built for straightforward fuse insertion and removal in place, which is what you want when a maintenance tech is swapping an SC fuse on a live-adjacent panel during a shutdown window. Standard practice still applies: de-energize before reaching into the enclosure.
