BUSSMANN 170E9713
The BUSSMANN 170E9713 is a high-speed fuse in a square body format for the protection of semiconductor components. It is designed for circuits where fault currents must be interrupted quickly to prevent damage to sensitive equipment. With a rated current of 375 A and a voltage rating of 3000 V AC, it is suited for demanding industrial installations.
The fuse is size 3 and features a bolted-tag connection according to DIN 43653. This makes it suitable for applications where a secure and robust installation is required. Additionally, it has a visual indicator on top, allowing for quicker identification of a blown fuse. This is a practical detail in service and troubleshooting, where it is often possible to locate a defective fuse without having to measure it first.
As a class aR fuse, it is intended for the protection of semiconductors. In practice, this means it is designed as part of the protection system for components that require fast and precise disconnection during a fault. It is therefore typically used in applications where the goal is not just to protect wiring and installations, but also the power electronics themselves.
