Bussmann ABC-30-R Series Fast-Acting Small-Dimension Fuse, 125V

The Bussmann ABC-30-R is a fast-acting, small-dimension fuse manufactured as part of the Eaton Bussmann series, a well-known line of circuit protection products used across residential, commercial, and industrial electrical systems. Rated for 125V circuits, this fast-acting fuse is engineered to respond quickly to overcurrent conditions, helping to safeguard connected wiring, components, and equipment from damage caused by short circuits or current surges. The small-dimension form factor of the ABC-30-R allows it to be used in compact fuse holders, panels, and equipment enclosures where standard-size fuses will not fit. Whether specified for a new installation or used as a direct replacement in an existing 125V circuit, the ABC-30-R offers electricians, panel builders, and maintenance technicians a dependable option from the trusted Eaton Bussmann series.

Key Features

  • Fast-Acting Response: The ABC-30-R is a fast-acting (quick-blow) fuse designed to open the circuit rapidly once current exceeds its rated threshold, helping protect downstream wiring and components from damage during a fault.
  • Small-Dimension Form Factor: This fuse is manufactured in a small-dimension body style, making it well suited for equipment, control panels, and enclosures where physical space is limited.
  • 125V Rating: Rated for 125V circuits, the ABC-30-R is intended for use in low-voltage power and control applications that call for a compact, fast-acting fuse.
  • Eaton Bussmann Series Construction: Manufactured as part of the Eaton Bussmann series, the ABC-30-R reflects the engineering and manufacturing standards associated with the broader Bussmann fuse portfolio.
  • Reliable Overcurrent Protection: As a fuse, the ABC-30-R is designed to be the sacrificial link in a circuit, opening to interrupt current flow and helping protect more costly downstream components and wiring when an overcurrent condition occurs.
  • Compact Fuse Holder Compatibility: The small-dimension body style of the ABC-30-R is sized to install into fuse holders and fuse blocks designed for small-dimension fuses, simplifying installation in tight spaces.
  • Model ABC-30-R Identification: The ABC-30-R designation allows for accurate identification, cross-reference, and replacement when specifying or reordering this fast-acting fuse.

Bussmann ABC-30-R – Frequently Asked Questions

1) What voltage is the Bussmann ABC-30-R fuse rated for?
The ABC-30-R carries a 125V rating, so it belongs in low-voltage power and control circuits. Do not drop it into a higher-voltage circuit on the assumption that an ABC body style is interchangeable across voltages; the voltage rating is the limit on where a fuse can safely interrupt a fault.
2) Is the ABC-30-R a fast-acting or time-delay fuse?
Fast-acting, sometimes called quick-blow. The ABC-30-R opens rapidly once current passes its rated threshold, which suits instrumentation, control circuits and electronic equipment where downstream components will not survive a prolonged overload. If the load has a heavy inrush at startup, such as a motor or a transformer, a fast-acting fuse will nuisance-trip and a time-delay type is the right choice instead.
3) Will the ABC-30-R fit a standard fuse block, or does it need a special holder?
It is a small-dimension fuse, so it goes into holders and fuse blocks built for small-dimension bodies, not into holders sized for standard-size cartridge fuses. That is what makes it workable in control panels and tight equipment enclosures, but it also means a holder meant for a larger class of fuse will not retain it.
4) Can I use the ABC-30-R as a direct replacement for an existing Bussmann ABC fuse?
Yes, where the fuse coming out is an ABC-30-R. It is part of the Bussmann ABC series and is intended both for new installations and as a direct replacement in an existing 125V circuit. Match the printed designation on the old fuse end cap before ordering, since an ABC-numbered fuse of a different ampere designation is not the same part.
5) What is the manufacturer part number for the Bussmann ABC-30-R?
Order it as ABC-30-R, an Eaton Bussmann part. That designation is what you use for cross-reference and reorder, and the UPC on the carton is 051712542487.
6) Where is the ABC-30-R typically used on the job?
Typical placements are overcurrent protection in 125V circuits, electronic and electrical control equipment, low-voltage power supplies, instrumentation and control circuits, and panel-mounted holders where space is constrained. For MRO stock it is also used to keep existing Bussmann fuse installations running without redesigning the holder.
7) Where do I get the full electrical specs for the Bussmann ABC fuse?
Eaton publishes a spec sheet PDF for the ABC series, and that document carries the detailed electrical data behind the 125V rating. The data held here covers the essentials for ordering: Bussmann ABC series, fast-acting, small-dimension body, 125V.
