Bussmann ANN-100 Circuit Limiter Fuse, 100A, Stud Mount, Non-Indicating

Bussmann ANN-100 Circuit Limiter Fuse, 100A, Stud Mount, Non-Indicating

The Bussmann ANN-100 is an Eaton Bussmann series ANN circuit limiter engineered to deliver precise overcurrent protection in commercial and industrial electrical distribution equipment. This 100A-rated circuit limiter is built to Eaton Bussmann's exacting standards, offering an interrupt rating of 2.5 kAIC at 125 Vac and 2.7 kAIC at 80 Vdc for dependable performance across both AC and DC circuits. With a voltage rating up to 130V, the ANN-100 is constructed with a blade end X blade end configuration and is also available for stud mounting, giving panel builders and electricians flexible termination options. As a non-indicating device, the ANN-100 delivers straightforward overcurrent protection for applications where a blown-fuse indicator is not required, making it a practical component for panelboards, switchboards, and other power distribution assemblies.

Key Features
