FAQs
The KAC-225 is a high-speed fuse designed to protect DC bus rectifiers, power supplies, and motor-drive circuits in industrial panels. With a 225 A rating and 200 kAIC interrupt capability, it rapidly clears faults to minimize equipment damage and downtime. It uses blade-end x blade-end connections with a stud mounting option for flexible installation.
Yes. The KAC-225 carries UL Recognized certification and CE marking, confirming compliance with widely adopted safety standards. These approvals support regulatory acceptance in many regions, streamline panel approvals, and enable safer, certified integration into global electrical installations.
The KAC-225 supports blade end x blade end connections and a stud mounting method. This combination provides robust, vibration-resistant installations and compatibility with common enclosure layouts, simplifying retrofits and new builds alike while maintaining secure conductor termination.
Ideal for rectifier banks, DC buses, and power conversion equipment in industrial drives and switchgear. Its 225 A rating and 200 kAIC interrupt capability make it suitable for high-energy DC protection while maintaining compact footprint and ease of integration within Bussmann Tron family designs.
As a non-indicating fuse, the KAC-225 relies on system-level status signaling rather than an onboard indicator. Plan replacements based on ambient operating conditions and manufacturer guidance, and keep spares within standard Bussmann Tron catalog parts to ensure quick procurement and consistent protection across panels.
