FAQs
The BK/JJS-3 is a current-limiting Class T fuse designed for 600 V distribution in multi-family and commercial installations. It provides fast interruption of short circuits while occupying minimal space, making it ideal for meter stacks, feeder protection, and compact switchgear. Its 3 A rating suits circuits requiring precise protection without nuisance tripping.
BK/JJS-3 is rated 3 A with a voltage rating of 600 V and an interrupt rating of 200 kAIC at 600 Vac. It features a small footprint (0.56 in length, 0.4 in width, 0.4 in height) and a bulk packaging option. The fuse is Class T and non-indicating with a rejection-style design to prevent incorrect installations.
Yes. The BK/JJS-3 provides high interrupt capability (200 kAIC) suitable for VFD line protection and feeder circuits while maintaining a compact form factor. Its Class T, current-limiting characteristics help protect drives and feeders from fault energy, making it a practical choice for multi-family meter stacks and apartment complex power distributions.
The BK/JJS-3 is CE marked and RoHS compliant, ensuring compliance with European regulatory requirements and environmental controls. While margins for other standards aren’t listed, these two signals support global applicability and responsible sourcing for engineering procurement teams.
The BK/JJS-3 is offered in bulk packaging, aligning with large-site stocking strategies and distributor procurement. Bulk notes and cataloging simplify reorder processes and inventory management for maintenance teams overseeing extensive apartment complexes or commercial facilities with frequent fuse replacements.
