Description
The Eaton Bussmann KTK-8 is an 8A fast-acting supplemental fuse designed to provide overcurrent protection in compatible low-voltage electrical circuits. Its 600V AC rating and compact cylindrical format make it suitable for specified control, lighting, and meter circuit applications.
The KTK series is designed for fast response, particularly in circuits with resistive loads. This model is a supplemental fuse and should not be confused with the KTK-R Class CC branch-circuit fuse series.
