Time-delay – 10 seconds (minimum) at 500% of rated current (8 seconds for 1⁄10-30A sizes). From the Manufacturer Heavy duty time-delay fuse used in motor protection. When sized correctly, it helps protect motors from burnout caused by overloads or single-phasing. The time-delay feature allows the initial startup current surge for typical motors to pass, but opens prior to motor burnout when longer, dangerous overloads are present. In addition, the dual-element design opens in as little as 0.004 second if the fuse experiences short-circuit conditions. UL Listed Class R (IR: 200kA). Groove in end cap or notch in knife blade permit the fuse to be used in Class H, Class K or Class R fuse blocks. Cartridge fuses are used to protect motors and branch circuits where higher amps or volt ratings are required. They are available in a wide variety of sizes, amp and volt ratings up to 600Vac and 600 amps. Cartridge fuses are used extensively in commercial, industrial and agricultural applications as well as residential fuse panels, air conditioning, pumps, appliances and other equipment. Cartridge fuses are available in two types. General Purpose fuses have no time-delay and protect fuse panels, appliances and branch circuits. Heavy- Duty fuses have a time-delay feature, allowing momentary motor startups. Both are available in 250Vac and 600Vac versions with catalog symbol and amp rating stamped on the knife blade or end cap. ## Features - Made in Mexico ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002GLALHI | | Best Sellers Rank | #66,911 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #100 in Cartridge Fuses | | Brand Name | Bussmann | | Current Rating | 100 Amps | | Customer Reviews | 4.6 4.6 out of 5 stars (94) | | Global Trade Identification Number | 00051712100137 | | Included Components | 1 Fuse | | Item Dimensions | 3.55 x 10.05 x 1.5 inches | | Item Type Name | Bussmann, Size Bussman BP/FRN-R-100 100 Amp T/D Fuse | | Item Weight | 5.76 ounces | | Manufacturer | Bussmann | | Material Type | Metal | | Maximum Current | 100 Amps | | Model | BP/FRN-R-100 | | Mounting Type | Surface Mount | | Part Number | BP-FRN-R-100 | | Specification Met | CE, CSA, UL | | UPC | 051712100137 | | Unit Count | 1.0 Count | | Voltage | 250 Volts | | Warranty Description | Warranty | ## Product Details - **AC Adapter Current:** 100 Amps - **Brand:** Bussmann - **Item dimensions L x W x H:** 3.55 x 10.05 x 1.5 inches - **Material:** Metal - **Voltage:** 250 Volts ## Images ![Bussmann 100A FRN-R Heavy-Duty Time Delay Fuse - 1 Each - Image 1](https://m.media-amazon.com/images/I/61NV6mlLKJL.jpg) ![Bussmann 100A FRN-R Heavy-Duty Time Delay Fuse - 1 Each - Image 2](https://m.media-amazon.com/images/I/61DkjHc7szL.jpg) ![Bussmann 100A FRN-R Heavy-Duty Time Delay Fuse - 1 Each - Image 3](https://m.media-amazon.com/images/I/61KZ9N0PWDL.jpg) ![Bussmann 100A FRN-R Heavy-Duty Time Delay Fuse - 1 Each - Image 4](https://m.media-amazon.com/images/I/61QkdIS7myL.jpg) ![Bussmann 100A FRN-R Heavy-Duty Time Delay Fuse - 1 Each - Image 5](https://m.media-amazon.com/images/I/71aQoYuKXML.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/24045238-bussmann-100a-frn-r-heavy-duty-time-delay-fuse-1](https://www.desertcart.co.za/products/24045238-bussmann-100a-frn-r-heavy-duty-time-delay-fuse-1) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-22*
