Bussmann ANN-125 ANN Series Stud-Mount Fuse, 130V

The Bussmann ANN-125 is a stud-mount fuse from the Bussmann ANN Series, rated 130V for applications that call for a stud-mounted overcurrent protection device. As a member of the ANN fuse family, the ANN-125 is manufactured by Bussmann, a recognized name in circuit protection components used across commercial, industrial, and electrical distribution equipment. The stud-mount configuration allows this fuse to be installed directly into compatible stud-mount fuse blocks, fuse holders, and disconnect switches, providing a secure mechanical connection that helps maintain consistent electrical contact. Like other fuses, the ANN-125 is intended to open and interrupt current flow when a circuit experiences an overcurrent condition, helping protect connected wiring and equipment. Electricians and maintenance teams specifying stud-mount fuses for 130V-rated circuits can identify this component by its Bussmann ANN Series model designation, ANN-125.

Key Features

  • Model Designation: ANN-125, part of the Bussmann ANN Series of stud-mount fuses, making it straightforward to identify and cross-reference for replacement or specification purposes.
  • Voltage Rating: Rated 130V, matching this fuse to electrical systems and equipment designed to operate within that voltage range.
  • Stud-Mount Design: Engineered with a stud-mount configuration, allowing the fuse to install directly into compatible stud-mount fuse blocks, panelboards, and disconnect switch fuse holders for a secure, vibration-resistant connection.
  • Product Type: Classified as a fuse, a fundamental overcurrent protection device used to interrupt current flow when a circuit experiences a fault condition.
  • Bussmann Brand: Manufactured under the Bussmann brand name, a recognized supplier of fuses and circuit protection products for electrical professionals.
  • ANN Series Family: Belongs to the broader Bussmann ANN Series lineup of stud-mount fuses, offering continuity of design and mounting style across the family.
  • Replacement Compatibility: As a Bussmann ANN Series stud-mount fuse, the ANN-125 is well suited as a like-for-like replacement in equipment originally specified with ANN Series stud-mount fuses.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

The stud-mount format and 130V rating of the Bussmann ANN-125 make it well suited to installations such as:

  • Stud-Mount Fuse Blocks and Fuse Holders
  • Disconnect Switches and Safety Switches
  • Overcurrent Protection in Electrical Panels
  • Commercial and Industrial Power Distribution Equipment
  • Motor Control Centers and Switchgear
  • Equipment and Systems Requiring 130V-Rated Fuse Protection

Why Bussmann?

Bussmann has long been recognized within the electrical industry for its circuit protection products, and the ANN-125 stud-mount fuse continues that focus with its 130V rating and stud-mount construction. Selecting a Bussmann ANN Series fuse for stud-mount fuse blocks and disconnect switches means specifying a component designed to fit an established mounting standard, simplifying installation and future replacement. For electrical contractors, panel builders, and maintenance professionals who value straightforward sourcing and consistent fit across a fuse family, the Bussmann ANN-125 offers a dependable stud-mount fuse option rated for 130V applications.

Bussmann ANN-150 – Frequently Asked Questions

1) What amp ratings are available in the Bussmann ANN Series stud-mount fuse?
The ANN Series stud-mount fuse comes in 60, 125, 150, 175, 225, and 400 amp ratings, ordered as ANN-60, ANN-125, ANN-150, ANN-175, ANN-225, and ANN-400. Pick the amp rating to match the circuit or the fuse you are replacing, since all of them share the same 130V rating and blade stud-mount body style.
2) Can I use a 130V ANN fuse on a 240V or 480V circuit?
No. The ANN fuse is rated 130V AC, so it belongs on low-voltage circuits at or below that rating, typically DC and low-voltage AC equipment. Putting it on a 240V or 480V system exceeds its voltage rating and it cannot be relied on to interrupt a fault safely. For higher system voltages you need a fuse rated at or above the circuit voltage.
3) How does the ANN fuse mount, and will it fit my existing fuse block?
It is a stud-mount fuse with blade terminals, so it bolts down through the blade holes onto the studs of a stud-mount fuse block, holder, or disconnect switch rather than clipping in. If the equipment was originally fitted with ANN Series fuses, the same amp rating drops straight back in. If your block uses ferrule or clip-style fuses, this will not fit.
4) Is the ANN a fast-acting or time-delay fuse?
Very fast acting, and circuit limiting. That makes it a protection choice for equipment that cannot tolerate let-through energy, such as semiconductor and rectifier circuits or sensitive switchgear. It is the wrong choice where you need to ride through motor inrush, since the fast element will open on starting current; a time-delay fuse is what that application calls for.
5) What size is the ANN-125 fuse body, and will it clear inside my panel?
The ANN-125 is listed at 2.8 inches wide and 1 inch high, weighing .27 pounds. Measure the stud center spacing in your block against the fuse before you commit, since the mounting holes have to line up on the studs for the blades to seat flat.
6) I manage a building and need to replace a blown fuse on a disconnect switch. How do I know I am ordering the right ANN?
Read the markings on the old fuse. If it says ANN followed by a number, that number is the amp rating and you order the same one, for example ANN-150 for a 150 amp. The ANN body style, 130V rating, and blade stud mounting are the same across the family, so matching the amperage is the only decision. Never go up in amp rating to stop nuisance blowing, the rating is set by the wiring and equipment it protects.
7) Where can I get the full time-current curve and dimensional data for Bussmann ANN fuses?
Bussmann publishes a spec sheet for the ANN Series that carries the detailed electrical and dimensional data, and it is linked from the product record as a PDF. For element melting curves and let-through data, that manufacturer document is the authority to work from when you are sizing coordination between the ANN and upstream devices.
