Bussmann CDN CSA Type D Time-Delay Fuse, 250V

The Bussmann CDN CSA Type D Time-Delay Fuse is part of the Eaton Bussmann series, engineered as a non-indicating, time-delay fuse for reliable overcurrent protection on 250V electrical distribution circuits. Built to CSA Type D specifications with a 10 kAIC interrupt rating, this fuse uses knife blade end x knife blade end terminations for secure connection in compatible fuse holders and blocks. This Bussmann fuse family is available in amp ratings ranging from 20A to 500A, allowing electrical professionals to match precise overcurrent protection to commercial, industrial, and panelboard circuit requirements.

Key Features

  • Amp Rating Range: Available in amp ratings from 20A to 500A, covering a wide span of circuit protection needs within a single Bussmann fuse family.
  • Voltage Rating: Rated 250V for standard electrical distribution circuits.
  • Interrupt Rating: 10 kAIC short-circuit interrupt rating supports safe fault clearing on protected circuits.

Bussmann CDN100 – Frequently Asked Questions

1) What amp ratings can I get the Bussmann CDN Type D fuse in?
The CDN family spans 20A to 500A. Orderable ratings are CDN20, CDN35, CDN40, CDN50, CDN70, CDN80, CDN90, CDN100, CDN175 and CDN500. Every one is the same 250V, 10 kAIC, non-indicating time-delay body, so you can standardize a panel on the series and only change the amp number per circuit.
2) Will a CDN fuse fit my existing fuse block?
The CDN uses knife blade end x knife blade end terminations, so it seats in blades-type blocks and holders, not in ferrule or plug-fuse clips. If what you pulled out had round ferrule caps or screwed in, the CDN is the wrong body style for that holder.
3) Can I use the Bussmann CDN on a 600V circuit?
No. The CDN is a 250V fuse and must not be applied above its voltage rating. For 600V distribution or motor circuits you need a 600V-rated fuse; the CDN is limited to 250V systems.
4) Why choose a time-delay fuse instead of a fast-acting one for a motor circuit?
Motors, transformers and similar inductive loads pull a heavy inrush for a fraction of a second at startup. The CDN's time-delay characteristic rides through that temporary surge without opening, then still clears a sustained overload or short. A fast-acting fuse at the same amp rating tends to nuisance-blow on every start. Use fast-acting where the load is resistive or electronics need quick clearing, and time-delay like the CDN on motor and equipment circuits.
5) Will I be able to tell by looking whether a CDN fuse has blown?
No. The CDN is a non-indicating fuse, so there is no pop-out pin or window to show it has opened. Maintenance crews have to check continuity with a meter or measure voltage across the holder. If you want a visual blown-fuse flag for a panel that gets serviced by non-electricians, specify an indicating fuse instead.
6) What does CSA Type D mean on this Bussmann fuse, and does it matter for a Canadian job?
The CDN is built to CSA Type D, the Canadian Standards Association classification for this fuse type. If your drawing or inspector calls out a CSA Type D fuse for a 250V panelboard or switchboard, the CDN meets that call-out. Type D is a time-delay classification, which is why it suits motor and transformer circuits.
7) I have a mix of amp ratings across a building's panels. Can I stock one Bussmann series for all of them?
For 250V circuits, yes within 20A to 500A. Ten CDN ratings cover that span (20, 35, 40, 50, 70, 80, 90, 100, 175 and 500 amps), all sharing the same knife blade ends, 250V rating and 10 kAIC interrupting rating. That lets an MRO stockroom carry one series and one holder style. Anything above 500A or above 250V falls outside the CDN family.
8) How do I order the right replacement if the old fuse is unreadable?
Match the amp rating stamped on the fuse block or the panel schedule, then order the CDN with that number after it, for example CDN100 for a 100 amp circuit. Also confirm the holder takes knife blade ends and that the circuit is 250V or less. Do not size up the amp rating to stop repeat blowing; that defeats the conductor protection.
