Specifications:
The HE7aR series semiconductor fuses are designed for use in DC circuits with a voltage rating of 750V and current ratings ranging from 10A to 100A. These fuses have an interrupting capacity of 50,000 amperes at 750V DC. They comply with standards IEC 60269-4, GB/T 13539.4, and UL 248-13.
Technical Parameters:
The fuses are available in various current ratings: 10A, 16A, 20A, 25A, 32A, 40A, 45A, 50A, 63A, 80A, and 100A. All models have received safety approvals from cURus, CCC, and TUV.
Dimensions:
The dimensions for the fuses are consistent across the range, with specific measurements provided for parameters A through K in millimeters. For example, the length (A) is 44.5±1 mm, and the width (B) is 18.0±1 mm.
Average I-T Characteristics Curve:
The document includes an I-T curve graph for reference, illustrating the time-current characteristics of the fuses. This curve helps in understanding the response time of the fuses under different current loads.
