FAQs
BK-FWH5-12-5A6FR is designed for standard Bussmann series compatibility with common industrial control panels. It supports 500 V systems, 12.5 A current rating, and 50 kAIC interrupt capability, enabling straightforward replacement in compatible Bussmann housings and feeders without additional adapters. Ensure panel space and bus bar clearances meet equipment datasheets during retrofits.
Rely on the 12.5 A amperage rating, 500 V voltage rating, and 50 kAIC interrupt capacity. These specs enable fast fault interruption to protect motor drives and drive electronics from short-circuit events, reducing arc energy transfer and downtime. For best results, coordinate with system voltage and inrush characteristics and consider selective coordination with upstream protection.
Yes. The 12.5 A 500 V rating and 50 kAIC interrupt capacity support typical conveyor and packaging line protection requirements. Its high-speed behavior minimizes damage from faults while its non-indicating design simplifies installation in tight control panels. It also conforms to CE RoHS and CSA standards, aiding compliance in regulated manufacturing environments.
The fuse carries CE Marking, RoHS compliance, and CSA certification. CE marks ensure conformity with EU safety and performance directives, RoHS restricts hazardous substances, and CSA certification verifies electrical safety for North American markets. Together they reduce audit findings, simplify supplier qualification, and support regulatory-ready deployments.
The fuse delivers rapid fault interruption (50 kAIC) to protect expensive equipment, reducing downtime and maintenance costs. Its standard packaging and 100-unit quantity streamline procurement for OEMs and integrators, enabling cost-effective stocking. While upfront costs are modest, the long-term savings come from less unplanned downtime, fewer component failures, and smoother regulatory compliance audits.
