Bussmann provides the easiest and fastest way to select and specify the right fuse. By grouping our low voltage fuses into three tiers of protection, and four fuse families within those tiers, we've sped up specification and selection and made replacement easy. Leveraging our ultimate protection fuses, the Bussmann Low-Peak™ Upgrade program couples the industry's most advanced circuit protection with our extensive technical knowledge to deliver enhanced safety, improved system reliability and simplified inventory.

Current-limiting fuses are designed to limit the amount of current that can pass through them. This feature is particularly beneficial in electrical systems where fault currents can reach high magnitudes. Here’s how these fuses support safety, reliability, and efficiency:

1. Enhanced Safety: Current-limiting fuses enhance workplace safety by reducing the incident energy personnel are exposed to under fault conditions. This minimizes arc flash hazards and prevents thermal and magnetic forces that could pose risks to personnel and equipment. This safety feature is particularly important in the context of Bussmann’s Low Peak Upgrade program, which revolves around the advanced current-limiting characteristics of their fuses.

2. Improved System Reliability: The fast response speed of current-limiting fuses allows them to clear fault currents within the first half or quarter cycle, protecting downstream equipment from damage. This capability ensures uninterrupted operation of critical systems and reduces downtime.

3. Selective Coordination: Current-limiting fuses simplify selective coordination requirements by maintaining a minimum amp ratio between upstream and downstream fuses. This ensures that only the faulted circuit is interrupted, preventing unnecessary power loss to upstream circuits and improving system performance.

4. Reduced Inventory: By offering versatile fuse options that can replace multiple fuses in various applications, programs like Bussmann’s Low Peak Upgrade simplify inventory management. This reduction in stocking requirements streamlines maintenance processes and reduces costs associated with managing multiple fuse types.

Enhanced safety

• Superior current-limitation performance minimizes incident energy associated with an arc flash. This helps to reduce arc flash hazards to their lowest levels possible. Replacing fuses with Bussmann series Low-Peak fuses improves the safety level of the electrical system.

• UL® Listed interrupting rating up to 300 kA allows the fuse to safely interrupt a circuit under the worst fault conditions.

• Finger-safe design of the Class CF CUBEFuseTM offers protection against shock hazards.

• Compliance with safety standards such as NFPA 70E, NEC® 110.16, IEEE® 1584, OSHA® 29 CFR® 1910 and 1926 and UL 508E helps minimize risk to employees

Improved system reliability

• Type 2 "No damage*" motor starter protection allows the contactor and overloads to be put back in service after a fault without an expensive outage for repair or replacement. Preventing equipment damage helps reduce downtime associated with destructive fault currents.

• Optional fuse indication** on Class CF, J and RK1 fuses allows for faster troubleshooting.

• Superior current-limitation feature helps increase equipment shortcircuit current ratings by reducing fault currents and can help comply with NEC 110.10.

• 2:1 amp ratio between upstream and downstream Bussmann series Low-Peak fuses makes confirmation of selective coordination quick and easy, which helps prevents blackouts

Simplified inventory

• Bussmann series Low-Peak fuses are available in UL Class CC, CF, J, L and RK1, so there is a fuse to meet the vast majority of 250 and 600 V overcurrent protection needs.

• One Low-Peak fuse can be used for multiple applications, which reduces the number of SKUs that need to be kept in stock by up to 33%. This saves time and money associated with ordering and stocking fuses. The estimated annual savings is calculated at $125 per SKU eliminated.

• Signature Low-Peak yellow label enables visible recognition and allows for quick and easy replacement. Each label has been designed with a consistent look and feel with critical information presented in an easy-to-read format.

How the Low-Peak Upgrade program works

How much does this program cost? FREE

We are so confident that our Bussmann series Low-Peak fuses will help you achieve ultimate protection while reducing your inventory, that we offer this service free of charge.

How long does the process take? APPROXIMATELY 1 WEEK

Once your inventory is physically counted and submitted to our team, the development of the reports generally takes about 5 business days. We'll let you know if we need more information.

What will I receive? DETAILED REPORT

When we've completed our analysis, we'll provide a detailed consolidation report that includes:

• Number of SKUs eligible for upgrade and elimination

• Percentage of inventory reduction

• Estimated annual savings

• Quote to purchase new Bussmann series Low-Peak fuses

• One-time buy back credit offer in exchange for existing inventory being recommended

• Detailed recommended inventory list When the Low-Peak Upgrade program is implemented, we provide training on our Bussmann series Low-Peak fuses and any other circuit protection topic needed as well as convenient cross reference materials for your storeroom.

Case study

A power plant used various types and sizes of fuses in their facilities panelboards, motor control centers and control panels. Over the years, they had accumulated a mixed inventory and stocked over 236 different fuse SKUs.

After completing the Bussmann series Low-Peak Upgrade program and implementing the proposed consolidation, the customer eliminated 55 fuses from inventory. At $125* per line item, this amounted to an annual savings of $6,875 and a 23% reduction in fuse inventory.

Additionally, the customer took advantage of our buy-back program to establish a fresh, optimized inventory

*Estimated cost savings based on the cost of forecasting, purchasing, receiving, invoicing, stocking and shipping inventory

The Low-Peak Upgrade program offers superior performance while reducing the number of SKUs that need to be in stock. Bussmann series Low-Peak fuses feature a high degree of current limitation to help provide the superior component protection and help mitigate arc flash hazard.
