FAQs
BK/JJS-200 is designed for standard Bussmann JJS style fuse blocks and fit within commonly used panel footprints. With dimensions of 3.25 in by 3.25 in and a slim 0.88 in height, the unit installs in space-constrained enclosures and supports straightforward field replacement without special adapters. This compatibility minimizes retrofit time and ensures reliable, repeatable installations across projects.
The BK/JJS-200 carries a 200 A amperage rating and a 200 kAIC interrupt rating at 600 V. It is a current-limiting fuse with Class T designation and non-indicating operation, designed to provide fast fault interruption while maintaining compatibility with 600 V power systems. These specs support protection of VFD drives, feeders, and high-current distribution paths.
Yes. The 200 A rating and high interrupt capacity make BK/JJS-200 appropriate for large meter stacks and feeder protection in multi-family buildings. Its compact form factor aids dense installations, while bulk packaging lowers procurement complexity for scale projects. The fuse’s reliability helps minimize downtime during faults and service windows.
BK/JJS-200 is CE marked and RoHS compliant, aligning with European and global safety and environmental requirements. It uses a Class T fuse design with non-indicating indicators, providing predictable protection behavior. This combination supports regulatory audits and international deployments without extra accessory needs.
The fuse is sold in bulk, reducing unit cost and simplifying large-scale stocking for projects like apartment complexes and commercial facilities. Its robust interruption rating and standardized dimensions speed maintenance, while regulatory compliance reduces lifecycle risk. Overall, expect lower downtime, faster replacements, and improved asset protection over time.
