Bussmann / Eaton CUBEFuse™ Circuit Fuses & Holders

Bussmann / Eaton CUBEFuse™ Circuit Fuses and Holders are a finger-safe industrial fuse system that minimizes exposure to live parts. These devices feature a dual-element fuse construction while offering interrupt ratings from 50kA DC to 300kA DC, voltage ratings of 600VAC (or less), and an amperage range from 1A to 100A. Both the holders and switches have an amp rating rejection feature to help prevent over-fusing and an operating temperature range of -40°C to +80°C or +90°C.

The CUBEFuse holders include single-pole 30A, 60A, 100A, 200A, 225A, and 400A holders. All of these holders can be dovetailed together to create the number of poles needed for an application, including mixed amp ratings between the 30A, 60A, and 100A holders.

Bussman / Eaton CUBEFuse Circuit Fuses and Holders offer a small footprint and are ideal for photovoltaic systems, including combiner boxes, re-combiner boxes, and DC safety switches.
