Eaton Bussmann 170M6415 1100A 690V AC aR High-Speed Semiconductor Fuse

Description

Product Overview
The Bussmann 170M6415 high-speed fuse is part of Eaton’s range of square-body semiconductor protection fuses. It is designed for industrial systems where power semiconductors and associated components require fast-acting short-circuit protection.
Its Class aR utilization category provides partial-range semiconductor protection. This means the fuse must be coordinated with the equipment’s wider protection system, including any separate overload protection required by the application.
The 170M6415 is rated at 1100A, with a 690V AC rating under IEC specifications and a 700V AC rating under UL specifications.

Installation and Compatibility Guidance
Before replacing this fuse, verify the exact model, current rating, voltage rating, Class aR designation, mounting dimensions and required time-current and I²t characteristics.
Class aR fuses do not provide complete overload protection in every application. Ensure that the fuse is coordinated with the rest of the protection system and the equipment manufacturer’s requirements. Installation should be performed by a qualified electrical professional using appropriate isolation and safety procedures.
