Eaton Specification Sheet - BK/ALS-250B
250 A at 36 Vdc rating provides direct protection for high-capacity power circuits within lift trucks and their battery chargers, reducing the risk of downstream damage and costly downtime. Business impact: fewer unplanned outages and less wear on critical components; application: use on primary power paths and charging circuits to ensure rapid isolation of faults. Bulk packaging simplifies inventory management, reduces procurement cycles, and lowers stocking costs in fleet maintenance programs. The non-indicating design minimizes field indicators to monitor, shifting status awareness to centralized systems and saving labor during routine checks. Silver-plated fuse caps enhance contact reliability and longevity, delivering consistent performance in dirty or high-vibration environments. Compatibility with the Bussmann ALS family ensures straightforward replacement and standardized maintenance across mixed forklift fleets, while a compact form factor (3.75 in L × 1.63 in W × 1.63 in H) fits crowded panel spaces without compromising protection. Industry context: ideal for material handling and manufacturing sites seeking dependable, low-maintenance electrical protection that scales with rising energy demands.

FAQs
The product listing marks warranty and compliances as Not Applicable, and regional certifications should be confirmed with Eaton’s datasheet. In practice, ALS fuses are commonly evaluated against CE, UL, and other market-specific standards; always verify the latest approvals for your region and application to ensure regulatory compliance and safe operation in lift truck and charger environments.
Yes, the BK/ALS-250B is part of the Bussmann ALS family designed for compatibility with standard ALS fuse holders and trays used in forklift power circuits and charging stations. When selecting, match the amperage rating and voltage (250 A, 36 Vdc) and ensure the physical dimensions align with your holder to ensure secure installation and reliable protection.
The fuse measures 3.75 inches in length with a cross-section of 1.63 by 1.63 inches and weighs 0.15 lb. It is offered in Standard Bulk packaging, with catalog notes indicating Bulk availability. This sizing fits compact panels and supports bulk stocking strategies to reduce downtime when replacements are needed in busy fleet operations.
Non-indicating fuses are favored in environments where centralized fault monitoring is standard or where visual indicators could be obscured by dust or vibration. For forklift and charger systems, this simplifies field maintenance while relying on software or panel indicators for status, enabling faster replacement cycles and improved reliability in high-duty industrial settings.
The BK/ALS-250B is rated for 250 A at 36 Vdc, intended to protect high-current DC circuits in lift trucks and battery chargers. For safe operation, ensure proper coordination with downstream protection and follow Eaton’s datasheet guidance on installation, derating, and replacement intervals to maintain protective performance and system safety.
