aR FUSE HE7aR 750V DC 125A-200A

Product catalog summary
Product Overview: The HE7aR series semiconductor fuses are designed for protection in DC circuits with a voltage rating of 750V and current ratings ranging from 125A to 200A. These fuses have an interrupting capacity of 50,000 amperes at 750V DC.
Standards and Approvals: The fuses comply with international standards IEC 60269-4, GB/T 13539.4, and UL 248-13. All models (HE7aR125, HE7aR160, HE7aR180, HE7aR200) have received TUV safety approvals, indicated by a filled circle (●).
Technical Parameters: The document lists part numbers and their corresponding current ratings: HE7aR125 (125A), HE7aR160 (160A), HE7aR180 (180A), and HE7aR200 (200A). Dimensions are provided in millimeters with specific tolerances for each measurement.
Dimensions: The dimensions of the fuses are specified as follows: 98±5 mm, 78±4 mm, 14±0.7 mm, 9±0.5 mm, 20±1 mm, 23±1.2 mm, 50±3 mm, 3±0.2 mm, and 26±1.3 mm.
Performance Characteristics: An average I-T characteristics curve is provided for reference, showing the relationship between current (in amperes) and time (in seconds) for different current ratings (125A, 160A, 180A, 200A).
