This is Bussmann's 40-2000A Electrical Characteristics Ordering Information table.
The Square Body DIN 43 653 fuse from Cooper Bussmann is a high‑current, high‑voltage protective device designed for use in industrial and commercial electrical systems. It is rated for IEC/U.L. voltages of 660 V/700 V and can handle continuous currents from 40 A up to 2000 A.
The datasheet provides detailed electrical characteristics, including total clearing current, arc voltage curves, power loss calculations, and an interrupting rating of 300 kA RMS symmetrical. Dimensional data for the various DIN 43 653 type configurations (‑/80, ‑TN/80, ‑/110, ‑TN/110) are also included to aid in panel layout and installation.
