This document provides information on the electrical characteristics and ordering information of Bussmann® 12-28-98 SB98107 Rev. A Square Body – DIN 43 653 1250V/1300V (IEC/U.L.) 50-1400A.
This document is a technical bulletin (Form No. SB98107 Rev. A) for Cooper Bussmann Square Body fuses designed to DIN 43 653 Type -T/110 standards. It covers voltage ratings of 1250V IEC and 1300V U.L., with current ratings ranging from 50A to 1400A.
The datasheet provides detailed electrical characteristics, including total clearing energy (Pt), interrupting rating (300kA RMS Symmetrical), arc voltage curves, and power loss calculations. It also lists physical dimensions for sizes 1* through 3 in millimeters.
| Rated Voltage (IEC) | 1250V |
|---|---|
| Interrupting Rating | 300kA RMS Symmetrical |
| Current Range | 50-1400A |
| Standard Compliance | DIN 43 653 Type -T/110 |
The interrupting rating is 300kA RMS Symmetrical.
Multiply the watts loss at rated current by a correction factor, Kp, based on the load current percentage.
Size 3 fuses measure 81.1mm x 139mm x 90mm with an E dimension of 76mm and H dimension of 30mm.
