aR FUSE H2FF 250A-800A

Product catalog summary
Product Overview: The document provides technical specifications for the H2FF series fuses, ranging from 250A to 800A, designed for high interrupting capacity applications. These fuses are classified under the operation class 'aR' and are suitable for both AC and DC circuits.
Interrupting Capacity: The fuses have an interrupting capacity of 100,000 amperes at 1250V AC and 50,000 amperes at 1000V DC.
Standards and Approvals: The fuses comply with IEC 60269-4, GB/T 13539.4, and UL 248-13 standards. They have safety approvals from TUV, CCC, and CE.
Technical Parameters: The document lists various part numbers corresponding to different current ratings (250A to 800A) and their respective voltage ratings (1250V AC and 1000V DC). All listed models have obtained safety certifications.
Optional Accessories: Microswitches (HMC-01) are available as optional accessories for these fuses.
Dimensions: The dimensions are provided in millimeters, with specific measurements for different parts of the fuse.
Average I-T Characteristics Curve: A reference curve is included, showing the relationship between current (in amperes) and time (in seconds) for various current ratings.
