Bussmann 170M6415 Fuse Link

Description:

The Bussmann 170M6415 Fuse Link is used in high-power electrical systems to provide ultra-fast protection for semiconductor devices, power converters, drives, and rectifier equipment against short-circuit and overcurrent conditions. Commonly installed in variable frequency drives (VFDs), UPS systems, DC drives, power conversion equipment, renewable energy systems, and industrial motor control applications requiring high-speed circuit protection. Maintenance electricians and system integrators use this fuse link for repair, retrofit, expansion, or replacement of existing semiconductor protection devices to maintain equipment reliability and minimize downtime. The fuse is rated at 1100A, 690VAC, 200kA interrupting capacity, Size 3, Class aR, and features a single top-mounted indicator.

Applications:

The Bussmann 170M6415 Fuse Link is commonly used in semiconductor protection circuits, variable frequency drives, soft starters, DC common bus systems, inverters, rectifiers, power supplies, and industrial automation equipment. Its Class aR high-speed design provides rapid fault clearing to protect sensitive semiconductor components from damage caused by short circuits and excessive fault currents. Bussmann high-speed square body fuses are widely utilized in demanding industrial and power electronics applications where equipment protection is critical.
