Eaton ALS-175B Fuse - Type B, 130 Vdc DC Protection
Part Number: ALS-175B
Quick Summary
ALS-175B fuse from Eaton provides reliable DC overcurrent protection for forklifts and battery chargers. Operators frequently face nuisance trips and hard-to-trace faults in high-current DC systems, which disrupt production and increase maintenance time. While the datasheet lists Compliances as Not Applicable, this fuse is designed to meet Eaton Bussmann's industrial fuse standards for demanding environments. The 175 A at 130 Vdc rating aligns with common forklift and charger protection schemes, enabling faster maintenance and lower total cost of ownership. The non-indicating design reduces alarm fatigue, and the silver-plated fuse caps improve contact reliability in dirty industrial settings, delivering consistent performance in harsh conditions.

FAQs
Begin by isolating the power source and opening the control panel. Confirm that the ALS-175B is the correct 175 A, 130 Vdc rating and that the packaging matches the equipment’s form factor. Insert the fuse with proper orientation, secure terminals, and verify continuity. Replace any damaged holders and restore power, then perform a functional test under load.
The ALS-175B provides non-time-delay DC protection at 175 A and 130 Vdc, matching typical charger surge profiles for forklifts and industrial batteries. Its Type B behavior ensures rapid response to overcurrent, while the silver-plated caps enhance contact reliability in dirty or humid environments, reducing maintenance intervals.
Key specs include 175 A amperage rating, 130 Vdc voltage rating, 3.75 in length, 1.057 in width, and 1.057 in height with a weight of 0.25 lb. These values determine the fuse’s ability to interrupt high-current faults in DC circuits commonly found in forklifts and chargers, while fitting standard Bussmann-series hardware for easy sourcing.
The data provided lists Compliances as Not Applicable for this part. While no region-specific certifications are stated here, the product is designed to fit Eaton Bussmann’s industrial fuse standards. For region-specific requirements, consult the official datasheet or Eaton’s compliance documents to confirm CE/SIL/IP ratings if applicable to your project.
By reducing nuisance trips, enabling faster fault isolation, and shortening downtimes in forklift and charger applications, the ALS-175B can lower maintenance costs and improve equipment availability. The durable construction, silver-plated caps, and standardized form factor also simplify procurement and spare-part management, contributing to reduced operational overhead over time.
