Eaton ALS-200B Fuse - 200 A, Non-indicating, 36 Vdc
Part Number: ALS-200B
Quick Summary
The ALS-200B fuse from Eaton provides non time-delay DC circuit protection for forklifts, battery chargers, and other 36 Vdc systems. Engineers often struggle with selecting the correct amp rating for high-current DC drives, risking nuisance blows or insufficient protection. While the unit is designed for demanding industrial environments, always verify the specific certifications in the official datasheet; common protections in the industry include SIL, CE, and IP-based approvals. With a 200 A rating and compact form, it integrates cleanly into standard Bussmann ALS fuse holders, reducing wiring complexity and maintenance overhead. By combining a robust 36 Vdc rating with silver-plated fuse caps for improved conductivity, Eaton delivers reliable protection that supports forklift powertrains and battery charging stations, delivering uptime and predictable maintenance costs.

FAQs
ALS-200B uses the standard Bussmann ALS fuse form factor and fits in common fuse holders used in material handling and power conversion systems. It is designed for easy replacement in existing 3.75 inch long assemblies, and the data sheet provides exact dimensional compatibility for mounting trays and clips. This minimizes retrofit time and supports quick field replacements.
The ALS-200B is a non time-delay DC fuse rated for 200 A with a 36 Vdc voltage rating. Its dimensions are 3.75 in length with 1.63 in height and width, and it has a light 0.15 lb weight. The fuse is non-indicating and packaged in standard bulk quantities, suitable for bulk procurement and service stock.
Yes. With a 200 A rating and a 36 Vdc rating, the ALS-200B is well matched for forklift battery charging circuits and similar DC power paths. Its non-time-delay characteristic provides immediate protection in fault conditions, helping to prevent damage to chargers, controllers, and traction components.
The product data provided lists not applicable for certain compliances, so verify required certifications in the Eaton datasheet or via Eaton support. In practice, customers should confirm CE, UL, IP, or SIL requirements directly with Eaton to ensure conformance for their specific region and application.
Using the ALS-200B reduces downtime by delivering reliable, immediate DC protection for high-current 36 Vdc systems such as forklifts and chargers. Its compact, bulk-packaged design lowers spares inventory costs, while silver-plated capacitive ends improve conductivity, contributing to longer component life and lower maintenance costs over the equipment lifecycle.
