Bussmann KAX-10 Eaton Series KAX Semiconductor Fuse, 1500 Vdc Non-Indicating

Bussmann KAX-10 Eaton Series KAX Semiconductor Fuse, 1500 Vdc Non-Indicating

The Bussmann KAX-10 is part of Eaton's Bussmann series KAX line of semiconductor fuses, engineered to protect power semiconductors and DC circuits rated up to 1500 Vdc. This Non-Indicating fuse features a Standard speed characteristic, delivering fast, reliable interruption in high-voltage DC applications such as power conversion, inverter, and drive systems. Because semiconductor devices like thyristors, diodes, and IGBTs have very limited thermal overload capacity, a fuse purpose-built for this duty — like the KAX-10 — is essential to prevent damage during fault conditions. Its compact body makes it well suited for space-constrained enclosures and panel layouts where dependable overcurrent protection for semiconductor devices is critical to system uptime.

Key Features

• Voltage Rating: 1500 Vdc rating supports protection of power semiconductors in high-voltage DC circuits and DC bus applications.
• Series: Part of the Eaton Bussmann series KAX semiconductor fuse family, model KAX-10, purpose-built for power electronics protection.
• Indication: Non-Indicating design without a visual blown-fuse indicator, suited to standard panel-mount and busbar-mount applications.
• Speed: Standard speed characteristic tuned for coordinated protection of power semiconductor devices during overload and short-circuit events.
• Compact Form Factor: Measures 2 in in height with a .56 in x .56 in body footprint and weighs .47 lb, suiting tight equipment layouts and high-density fuse blocks.
• Semiconductor-Grade Design: Constructed specifically for the fast clearing and low let-through energy demanded by semiconductor protection, unlike general-purpose branch-circuit fuses.
