Bussmann BCM603-3P Class CC Modular Fuse Block, 3-Pole, 600-Volt, Up to 30-Amp

The Bussmann BCM603-3P is a Class CC modular fuse block designed to deliver compact, space-saving circuit protection for industrial and commercial electrical systems. Configured as a 3-Pole block, it accepts Class CC fuses and carries a 600-Volt rating with a current rating of up to 30-Amp, making it a practical choice for branch-circuit and control-circuit protection in panels where reliable, code-aware fuse mounting is essential. The modular fuse block construction allows electricians to mount, wire, and service fuses efficiently, helping streamline panel design in three-phase applications. This combination of pole count, voltage rating, and amperage rating makes the BCM603-3P a versatile building block for panelboards, control cabinets, and power distribution assemblies that call for Class CC protection.

Key Features

  • 3-Pole Configuration: The BCM603-3P provides three-pole fuse mounting from a single modular block, simplifying protection of three-phase branch circuits and reducing the number of individual fuse holders required in a panel.
  • Class CC Fuse Compatibility: Designed to accept Class CC fuses, giving installers a compact, standardized fuse-holder option for control and branch-circuit protection.
  • 600-Volt Rating: Rated for 600-Volt systems, supporting use across a wide range of industrial and commercial power distribution applications.
  • Amperage Rating: Rated up to 30-Amp, suitable for protecting branch circuits and control circuits within that current range.
  • Modular Block Design: The space-saving modular construction allows the fuse block to be mounted, wired, and serviced without disturbing adjacent circuit poles, supporting faster panel assembly and simplified maintenance.
  • Bussmann Build Quality: Manufactured by Bussmann, a recognized name in circuit protection components, for dependable performance in demanding electrical environments.

Bussmann BCM603-3P – Frequently Asked Questions

1) What fuses does the Bussmann BCM603-3P fuse block take?
The BCM603-3P accepts Class CC fuses only, rated to 600V and up to 30A. Class CC is a specific rejection-style ferrule fuse, so Class G, Class R, or midget fuses without the CC rejection feature will not seat correctly in it. If your panel drawing calls out a Class CC fuse at 30A or less on a 600V system, this block is the match.
2) Is a Class CC block like the BCM603-3P or a Class R block the right choice for my panel?
Class CC covers you to 30A and is the compact choice for control circuits, motor control centers, and three-phase branch circuits where panel space is tight. Above 30A, or where the spec calls out Class RK1/RK5 fuses, you need a Class R block such as the Littelfuse LFR60030-3CID, a 600V 30A three-pole Class R block. For small control transformer protection at 15A on DIN rail, the Littelfuse LFG60015-1SQDINR is a Class G option.
3) Will the BCM603-3P work on a 480V three-phase industrial panel?
Yes. The block carries a 600V rating, which covers 480Y/277V and 600V three-phase distribution as well as 208/240V systems. The fuse you install sets the actual interrupting and current protection, so pair it with a Class CC fuse rated for your system voltage at 30A or below.
4) What is the closest alternative to the Bussmann BCM603-3P for a 600V 30-amp three-pole fuse block?
The Bussmann BCM603-3P is a Class CC modular fuse block, 3-pole, rated 600V and up to 30A. The nearest three-pole alternative at the same voltage and current is the Littelfuse LFR60030-3CID, a Class R fuse block rated 600V 30A. The difference that matters is fuse class: the BCM603-3P takes compact Class CC fuses, while the LFR60030-3CID is built around the larger Class R (RK1/RK5) fuse body, so the two are not interchangeable in the same panel cutout or with the same fuse stock. Confirm which class the circuit was specified for before swapping.
5) I only need to protect a single control circuit at 600V, not a three-phase branch. Is there a smaller fuse block than the BCM603-3P?
Yes. The BCM603-3P is a 3-pole block, so you are paying for and mounting three poles whether or not you use them. For a single-pole control circuit at 600V, the Littelfuse LFG60015-1SQDINR is a one-pole Class G fuse block rated 600V 15A with DIN rail mounting. Two things change: the fuse class moves from Class CC to Class G, and the current ceiling drops to 15A, so it only suits circuits at or below that. If your control circuit needs Class CC fuses specifically, stay with Class CC hardware.
6) Can I use the BCM603-3P for a single-phase or two-wire circuit?
It's a 3-pole block, so it gives you three fuse positions in one body. You can use two of the three poles for a single-phase circuit, but you'll be paying for and mounting a pole you don't need. For one- or two-pole work, order the matching single- or two-pole Class CC block instead; for three-phase branch and control circuits the 3-pole version is what you want.
7) What is the exact part number to order this Bussmann 3-pole Class CC fuse block?
Order Bussmann BCM603-3P. The BCM prefix is the modular Class CC block family, 603 denotes the 600V 30A class CC rating, and the -3P suffix is the three-pole configuration. There is one configuration on this model, so there is no finish, mounting, or amperage option to specify separately.
8) Do I get the fuses with the BCM603-3P, or do I order them separately?
The BCM603-3P is the fuse block only. You order Class CC fuses separately, sized for the circuit and not exceeding the block's 30A rating, and you supply your own panel mounting hardware and conductors.
9) Which fuse block should I use instead of the Bussmann BCM603-3P if the panel is wired for DIN rail?
The BCM603-3P is a modular Class CC block intended to be mounted and wired as a block in panelboards, control cabinets, and distribution assemblies. If the cabinet is laid out around DIN rail, the Littelfuse LFG60015-1SQDINR is a DIN rail mount fuse block rated 600V 15A. Note that it is a Class G block, not Class CC, and its 15A rating is below the BCM603-3P's up-to-30A capacity, so verify your fuse size and class before you commit the rail space.
10) Can a Littelfuse POWR-BLOK be substituted for the Bussmann BCM603-3P?
Treat them as different products rather than drop-in equivalents. The BCM603-3P is a Class CC modular block that mounts and wires as a unit in a panel, where the Littelfuse LD Series POWR-BLOKS is a bolt-in mounting fuse block. The bolt-in attachment method and the Class CC fuse opening of the BCM603-3P are not the same install, so the hole pattern and the fuse stock both have to be checked. If your existing panel already uses Class CC fuses, the BCM603-3P keeps you on that fuse inventory.
11) Can I replace one fuse pole without pulling the whole block out of the panel?
Yes. The modular construction lets you mount, wire, and service the block without disturbing the adjacent circuit poles, which is the main reason maintenance crews favor it over three separate fuse holders in a crowded control cabinet.
