Product catalog summary
Average I-T Characteristics Curve: This document provides the average I-T (current-time) characteristics curve for the H0FD series fuses, which are designed for reference purposes. The fuses operate at 690V AC and 500V DC with current ratings ranging from 40A to 630A. They are classified under the operation class 'aR' for protection characteristics.
Standards and Interrupting Capacity: The fuses comply with standards IEC 60269-4, GB/T 13539.4, and UL248-13. They have an interrupting capacity of 200,000 amperes at 690V AC and 50,000 amperes at 500V DC.
Technical Parameters: The document lists various part numbers (H0FD40 to H0FD630) with corresponding current ratings from 40A to 630A. Each part number is available in three types: Type-A (with visual indicator), Type-C (with micro indicator), and Type-D (no visual indicator). Safety approvals are indicated by a filled circle (●) for approved and an empty circle (○) for pending approval.
Optional Accessories: Microswitches (HMC-01) are available as optional accessories for the fuses.
Dimensions: The dimensions for each type (A, C, D) are provided in millimeters, with specific measurements for width, height, and mounting hole size (M8).
Graphical Data: The document includes a graph plotting current (in amperes) against time (in seconds) for various current ratings, illustrating the time it takes for the fuse to interrupt the current at different levels.
