Bussmann REN-3 Renewable Time-Delay Fuse, Class H, 250VAC, 3A

The Bussmann REN-3 is part of the Eaton Bussmann Series REN line of renewable fuses, engineered to deliver dependable overcurrent protection in industrial and commercial electrical systems. Rated 3 A at 250 Vac with a 10 kAIC interrupt rating, this Class H fuse features a super lag, time lag characteristic that allows it to ride through momentary overloads while still clearing sustained fault currents. The ferrule end X ferrule end connection makes it a direct fit for standard ferrule-style fuse holders and clips commonly found on panelboards and fuse blocks. As a renewable design, the REN-3 is built to accept replacement fuse links, giving maintenance crews a practical way to restore protection without sourcing an entirely new fuse body. This makes the REN-3 well suited for facilities standardizing on Class H renewable fuses across multiple panel and switch locations.

Key Features

  • Amperage Rating: 3 A rating provides precise overcurrent protection for the intended branch circuit.
  • Voltage Rating: 250 Vac rating suits low-voltage AC electrical distribution systems.
  • Interrupt Rating: 10 kAIC interrupt rating supports reliable fault-current clearing.
  • Fuse Class: Class H classification for standardized dimensional and performance compatibility.
  • Time-Delay Performance: Super lag, time lag characteristic tolerates temporary current surges without nuisance opening.
  • Renewable Design: As a renewable fuse, the internal link can be replaced rather than discarding the entire fuse body, reducing long-term replacement cost.
  • Connection Type: Ferrule end X ferrule end connection for compatibility with standard ferrule fuse clips and holders.
  • Series Compatibility: Part of the Eaton Bussmann Series REN renewable fuse line, standardized for consistent fit and performance.
  • Packaging: Supplied in convenient packs of 10 units for stocking multiple spares.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • General Purpose Branch Circuit Protection
  • Industrial Equipment and Motor Control Circuits
  • Panelboard and Fuse Holder Replacement
  • Renewable Fuse Retrofit in Legacy Electrical Systems
  • Commercial Electrical Distribution Panels

Why Bussmann?

Bussmann fuses are built to defined Class H dimensional and performance standards, giving electricians and maintenance teams a dependable, code-compliant option for overcurrent protection. The renewable design of the REN-3 lets facilities restock link elements rather than replacing entire fuse bodies, supporting cost-effective long-term maintenance in panelboards and fuse holders across industrial and commercial sites. With its 3 A, 250 Vac, 10 kAIC rating and super lag, time lag response, the REN-3 delivers consistent, code-compliant performance for demanding electrical protection applications, and its ferrule end X ferrule end connection ensures straightforward installation into compatible fuse clips. Because the REN Series follows Class H dimensions, replacement stock remains interchangeable across compatible fuse holders industry-wide.

Bussmann REN-3 – Frequently Asked Questions

1) Will a Bussmann REN-3 fit my existing fuse holder or fuse clips?
The REN-3 is a Class H fuse with ferrule ends on both sides, so it drops into standard ferrule-style fuse clips and holders on panelboards and fuse blocks. Class H is a dimensional standard, which is why replacement stock stays interchangeable across compatible holders. If your switch takes knife-blade ends instead of ferrules, the REN-3 will not seat.
2) Is a Class H renewable fuse enough for my available fault current?
The REN-3 carries a 10 kAIC interrupting rating. If the available fault current at that point in the system is above 10 kA, a Class H fuse is the wrong choice and you need a higher interrupting current-limiting class instead. Below 10 kA, it clears properly.
3) Can I replace a blown Class H fuse in a legacy fused switch with a REN-3?
That is one of the main uses for it. Class H dimensions are standardized, so a ferrule-end REN-3 goes back into legacy panelboards and fused switches already built for Class H ferrule fuses, as long as you match the 3 A rating and stay at or below 250 Vac.
4) What does renewable mean on the REN-3 fuse, and why would a maintenance crew choose it?
Renewable means the fuse body stays in service and the internal fuse link gets replaced after it opens. For an MRO or facilities crew, that means stocking link elements rather than scrapping a whole fuse body every time a circuit faults. It only pays off if you actually stock the links, so plan the spares before standardizing on it.
5) Will a 3A time-delay fuse hold on a motor start without blowing?
The REN-3 has a super lag, time lag characteristic, meaning it rides through momentary inrush and overload while still opening on a sustained fault. That is why it shows up on motor control and industrial equipment circuits. A fast-acting fuse at the same 3 A would nuisance-trip on the same inrush.
6) What is the exact part number to order a 3 amp Bussmann renewable fuse?
Order it as REN-3, the 3 A 250 Vac member of the Eaton Bussmann REN renewable fuse line. The number after the dash is the amp rating, so other ratings in the same Class H ferrule body follow the same REN prefix.
7) How is the Bussmann REN-3 sold, individually or in a pack?
REN Series REN-3 fuses are supplied in packs of 10, which suits stocking spares across several panel and switch locations rather than buying one at a time.
