Technical Parameters:
The document provides technical specifications for a series of fuses with part numbers ranging from HBA70 to HBA400. Each part number corresponds to a specific current rating, starting from 70A up to 400A. All listed fuses have received safety approvals denoted by '●', indicating cURus certification.

Dimensions:
The dimensions of the fuses are provided in millimeters, with specific measurements such as 29.4 mm, 47.1 mm, and 67.4±0.8 mm.

Class of Operation:
The fuses operate under class aR, which is a protection characteristic.

Interrupting Capacity:
The fuses have an interrupting capacity of 100,000 A at 150V AC and 20,000 A at 150V DC.

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

Average I-T Characteristics Curve:
The document includes a reference graph showing the average I-T characteristics curve for various current ratings (70A to 400A). The graph illustrates the relationship between current (in amperes) and time (in seconds), indicating the time it takes for the fuse to operate at different current levels.
