Bussmann LKS Replacement Fuse Link, Non-Current-Limiting Renewable, 600V

The Bussmann LKS Replacement Fuse Link is a non-current-limiting, renewable fuse link engineered as the internal replacement element for Bussmann RES renewable fuseholders rated 600V. Rather than replacing an entire fuseholder assembly after a fault, maintenance teams simply install a fresh LKS link, restoring circuit protection quickly and at lower cost. This fuse link family is offered across a wide amp rating range — from 3A up to 500A — so a single RES fuseholder platform can be matched to the exact overcurrent protection level a circuit requires, from small control and lighting branch circuits up to large feeder and equipment loads.

Key Features

  • Broad Amp Rating Range: Available in 3A, 5A, 6A, 12A, 25A, 35A, 45A, 50A, 70A, 80A, 90A, 110A, 125A, 150A, 175A, 225A, 250A, 300A, 350A, and 500A ratings to match the exact protection requirement of the installed RES fuseholder.
  • 600V Rating: Rated for 600V systems commonly found in commercial and industrial power distribution equipment.
  • Non-Current-Limiting, Renewable Design: The internal fuse link is field-replaceable, letting maintenance personnel renew the fuse element in place instead of discarding and replacing the entire fuseholder body.
  • Direct RES Fuseholder Compatibility: Engineered as a replacement link for Bussmann RES-series renewable fuseholders, simplifying maintenance planning and spare-parts stocking.
  • Manufacturer Documentation Available: Detailed specification documentation is published for this fuse link family, including the LKS-110 reference configuration, to support proper selection and replacement.
  • Standardized Platform: Stocking one RES fuseholder design paired with the correct amp-rated LKS link reduces the number of unique fuse assemblies a facility must maintain.

Typical Applications

  • Renewable Fuseholder Element Replacement
  • Commercial and Industrial Power Distribution
  • Panelboard and Switchgear Circuit Protection
  • Feeder and Branch Circuit Protection at 600V
  • Maintenance and Retrofit of Existing RES Fuse Systems

Why Bussmann?

Bussmann is a long-established name in circuit protection, and the LKS replacement fuse link is built to restore RES renewable fuseholders to full 600V protection without the cost of replacing the complete fuse assembly. With ratings spanning from 3A through 500A, electricians and facility maintenance teams can standardize on a single renewable fuseholder platform while stocking only the specific amp-rated links their systems actually require, supporting reliable, code-compliant power distribution and faster turnaround after a fault.

Bussmann LKS-35 – Frequently Asked Questions

1) Will the Bussmann LKS fuse link fit my renewable fuseholder?
The LKS link is the internal replacement element for Bussmann RES-series renewable fuseholders rated 600V. It is not a standalone fuse and won't drop into a standard Class H, R, J or T fuse clip arrangement. If the holder in your gear is an RES renewable body, pull the old link and install the LKS of the same amp rating. If it isn't an RES holder, this is the wrong part.
2) Is the LKS link current-limiting?
No. The LKS is a non-current-limiting renewable design. If your equipment label or the drawing calls for a current-limiting fuse (for example to hold a downstream device within its series-rated or short-circuit current rating), the LKS will not satisfy that requirement and you need a current-limiting class fuse instead.
3) Can I use a 600V Bussmann LKS link on a 240V or 480V circuit?
Yes. The LKS link is rated 600V, and a fuse may be applied on any system at or below its voltage rating, so 240V and 480V distribution are both within range. What you cannot do is go the other way and use a lower voltage-rated link in a 600V holder.
4) Why replace just the fuse link instead of the whole fuse?
That is the point of a renewable design. After a fault, maintenance pulls the blown element out of the RES holder and installs a fresh LKS link rather than scrapping the complete fuse assembly. For a facility with a lot of 600V renewable holders in panelboards and switchgear, it means stocking small links by amp rating instead of full fuse bodies.
5) What do I order to stock spares for a facility running RES renewable fuseholders at 600V?
Stock LKS links in only the amp ratings your circuits actually use. Control and small lighting branches typically sit at the low end (LKS-3, LKS-5, LKS-6, LKS-12), motor and equipment circuits in the middle (LKS-45 through LKS-125), and feeders at the top (LKS-225 up to LKS-500). One RES holder platform plus the right links keeps the spare parts list short.
