Specifications:
The HEA-B series semiconductor fuses are designed for use in circuits with a voltage of 660V AC and current ratings ranging from 125A to 200A. These fuses have an interrupting capacity of 100,000 amperes at 660V AC.

Standards:
The fuses comply with the following standards: IEC 60269-4, GB/T 13539.4, and UL 248-13.

Technical Parameters:
The part numbers and their corresponding current ratings are as follows:

• HEA-B125: 125A
• HEA-B160: 160A
• HEA-B180: 180A
• HEA-B200: 200A

All listed models have received safety approvals from cURus and CCC.

Dimensions:
The dimensions of the fuses are provided in millimeters with specific tolerances:

• Length: 98±5 mm
• Width: 78±4 mm
• Other dimensions include various tolerances for different parts of the fuse.

Average I-T Characteristics Curve:
The document includes an I-T characteristics curve for reference, showing the relationship between current (in amperes) and time (in seconds) for different current ratings (125A, 160A, 180A, 200A). The curve is intended for reference only and illustrates the time it takes for the fuse to interrupt the circuit at various current levels.
