BUSSMANN KBC-50 Fuse

The BUSSMANN KBC-50 is a 50 A high‑speed semiconductor fuse from Eaton’s Bussmann series, engineered to provide rapid protection for power‑electronics circuits against overcurrent faults. This non‑indicating, stud‑mount device ships in standard Bussmann packaging, and is designed for straightforward mounting in compatible fuse holders and chassis. It is rated for up to 1200 V DC with an interrupt rating of 200 kAIC, enabling fast fault clearance in high‑energy DC paths and helping limit damage to downstream semiconductor devices. The KBC‑50 designation identifies the 50‑ampere current threshold, delivering predictable protection while supporting coordinated protection schemes in demanding industrial and high‑voltage environments. By combining a robust current rating with a high voltage rating, the KBC‑50 offers a reliable, compact solution for safeguarding power supplies, drives, and other high‑energy power electronics in modern facilities.
