Product catalog summary
Technical Parameters:
The document outlines the technical parameters for semiconductor fuses, specifically the H2FH series, with current ratings ranging from 100A to 450A. Each part number corresponds to a specific current rating and configuration, with options for microswitch bases and central indicators.

Specifications:
  • Current Ratings: 100A, 125A, 160A, 200A, 250A, 315A, 350A, 400A, 420A, 450A.
  • Safety Approvals: Pending for all models, indicated by a circle (○).
  • Standards: Complies with IEC 60269-4, GB/T 13539.4, UL 248-13.
  • Interrupting Capacity: 100,000 amperes at 2000V DC.

Dimensions:
Dimensions are provided in millimeters for different configurations, including options with and without central indicators and microswitch bases. The hole depth for M10 is specified as 10-11.5 mm.

Average I-T Characteristics Curve:
The document includes a reference curve for the average I-T characteristics, showing the relationship between current (A) and time (s) for various current ratings from 100A to 450A.
