The J636 Gould Fuse Reducer is designed to safely convert 60A fuses to 30A. This reliable reducer ensures optimal performance and enhances circuit protection in your electrical system. Its durable construction and easy installation make it a perfect choice for both new and existing applications, providing stability and efficiency for your project needs.
The J636 adapter inserts into a 60A-rated fuse holder or fusible disconnect and reduces the accepted fuse size down to 30A. This lets you protect a smaller circuit or load without replacing the entire fuse block or disconnect enclosure — a cost-effective solution for retrofits and load changes.
Gould's fuse product lines have transitioned through several owners over the years. If the J636 is no longer in current production, Northern Breaker Group specialises in sourcing obsolete and hard-to-find electrical components. Contact our Calgary, Edmonton, or Vancouver counters and we'll check our stock and supplier network for you.
The J636 is designed for use with standard cartridge-type fuses up to 30A, 600V. You should always match the fuse class (e.g., Class H, K, or RK as appropriate) to your circuit's protection requirements and ensure the fuse is rated for the available fault current. Consult the Canadian Electrical Code (CEC) and your AHJ if you're unsure which fuse class is required for your application.
