Bussmann WCF Wind CUBEFuse Class CF Dual-Element Fuse, Finger-Safe Non-Indicating

The Bussmann by Eaton WCF Wind CUBEFuse is a finger-safe, non-indicating Class CF fuse purpose-built for wind turbine electrical systems, protecting transformers, pitch and speed control circuits, and turbine HVAC and lighting loads. Built with a dual-element design and a glass-filled PES body, this CUBEFuse series is available in amp ratings from 1A up to 100A across 17 standard selections (1A, 3A, 6A, 10A, 15A, 20A, 25A, 30A, 35A, 40A, 45A, 50A, 60A, 70A, 80A, 90A, 100A), giving wind energy installers and maintenance crews a single finger-safe fuse platform sized for a wide range of turbine control and protection circuits, from small pilot and lighting loads up to larger transformer feeders.

Key Features

  • Amp Rating Range: the WCF Wind CUBEFuse is available in 17 standard ratings from 1A to 100A, covering transformer protection and turbine control circuit requirements across a single, consistent fuse platform.
  • Dual-Element Design: Class CF dual-element (Dual) construction provides coordinated overcurrent protection suited to the inrush and steady-state demands of turbine electrical equipment.
  • Finger-Safe, Non-Indicating: finger-safe body construction with non-indicating operation for safer handling and servicing inside crowded wind turbine nacelle and tower-base enclosures.
  • Durable Construction: molded from glass-filled PES (polyester) for mechanical strength, dimensional stability, and resistance to the vibration and thermal cycling found in turbine environments.
  • CUBEFuse Form Factor: compact, standardized CUBEFuse footprint shared across the entire WCF series, simplifying panel layout and fuse holder selection in space-constrained turbine control cabinets.
  • Application-Specific Design: engineered specifically for transformer protection, pitch and speed control systems, and turbine HVAC and lighting circuits found in wind generation equipment.
  • Standard Class CF Platform: Class CF, non-indicating CUBEFuse construction (Standard) gives specifiers a consistent, code-recognized fuse class across every amp rating in the WCF family.

Bussmann WCF3RN – Frequently Asked Questions

1) Is the Bussmann WCF CUBEFuse finger-safe for servicing a live turbine control panel?
The WCF Wind CUBEFuse uses a finger-safe body, so there are no exposed conductive surfaces to contact when you pull or seat a fuse in a crowded nacelle or tower-base enclosure. It's the non-indicating version, so there is no blown-fuse indicator pin on top, you diagnose an open fuse with a meter or by the holder's own indication rather than by looking at the fuse.
2) Will a WCF CUBEFuse fit in any Class CF fuse holder or CUBEFuse base?
The WCF is a Class CF CUBEFuse and shares the standardized CUBEFuse footprint across every amp rating in the series, so panel layout and holder selection stay consistent as you move up and down the amp range. Class CF is its own fuse class with its own base, it does not drop into a Class J, CC or RK clip or block, so the panel has to be built around a CUBEFuse holder.
3) What does the dual-element design in the WCF CUBEFuse actually do for a motor or transformer circuit?
Dual-element construction gives the fuse a time-delay characteristic: it rides through the inrush surge when a transformer energizes or a pitch motor starts, then still opens on a sustained overload. That's the whole reason to pick it for transformer protection and pitch and speed control circuits, a fast-acting element sized to run current would clear on every start. Configuration is listed as Dual-Element.
4) How do I order the right Bussmann WCF fuse, and what does the part number mean?
Order by amp rating, the part number is WCF plus the amps plus RN. A 30 amp is WCF30RN, a 100 amp is WCF100RN, a 1 amp is WCF1RN. The RN suffix is the non-indicating version of the Wind CUBEFuse, so every rating in the family reads the same way and you only have to change the number in the middle.
5) I need a blown-fuse indicator on my CUBEFuse, is the WCF the right one?
No. The WCF Wind CUBEFuse is the non-indicating build, the RN part numbers carry no indicator. If your maintenance procedure depends on a visual open-fuse indication at the fuse itself, you want an indicating CUBEFuse instead, or a holder that provides the indication. The WCF is the right choice where the panel or the meter does the diagnosing and you want the plain finger-safe body.
6) What amp ratings does the Bussmann WCF Wind CUBEFuse come in?
Seventeen ratings, and that is the complete set: 1, 3, 6, 10, 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90 and 100 amps. That span covers small pilot and lighting loads at the bottom end through transformer feeders at 100A, so a single fuse platform handles most turbine control and protection circuits and you stock one form factor instead of several.
7) Can the WCF CUBEFuse handle the vibration and temperature swings inside a wind turbine nacelle?
The body is molded from glass-filled PES, chosen for mechanical strength and dimensional stability under the vibration and thermal cycling a turbine sees. That is the specific reason this variant exists rather than a general-purpose CUBEFuse, it's built for nacelle and tower-base panels on wind generation equipment.
8) Which WCF amp rating should I use for turbine lighting and HVAC circuits versus a transformer feeder?
The low end of the range, 1A through 15A, is where the pilot, lighting and small control loads land, while turbine HVAC and larger transformer feeders push up into the 30A to 100A ratings. Size to the load and the circuit's overcurrent requirement, not to the fuse family, the point of the WCF series is that all 17 ratings share one Class CF footprint so a panel can mix small control legs and a transformer feeder in the same holder style.
9) Can I use the Bussmann WCF CUBEFuse outside of wind turbines, in a standard industrial control panel?
It's a Class CF dual-element fuse, so electrically it behaves like the CUBEFuse platform it belongs to and it will work in any panel built for a Class CF base within the fuse's rating. The WCF variant is specified for wind generation equipment, transformer, pitch and speed control, turbine HVAC and lighting, so the glass-filled PES body and dual-element curve are matched to vibration and inrush conditions. Nothing about it restricts it to a turbine, but if your application is a plain indoor panel, the standard CUBEFuse line is the more common specification.
