Fuses acc. to british standard (URE)

Product catalog summary
Overview: This document outlines the specifications and features of fuses designed for semiconductor protection, compliant with European-British standards IEC 60269-4 and BS 88-4. These fuses are classified under class aR, with voltage ratings from AC 240 V to AC 700 V and current ratings from 5 A to 900 A. They have a high interrupting rating of 100 kA and are available with a striker for microswitch operation.
Specifications:
  • Voltage Ratings: AC 240 V – AC 700 V
  • Current Ratings: 5 A – 900 A
  • Interrupting Rating: 100 kA
  • Standards Compliance: IEC 60269-4, BS 88-4
Selection Guide: The document provides a selection guide for various fuse sizes, part numbers, technical data, and rated voltages. Sizes range from 8.4 x 38 mm to 2 x 35 x 85 mm, with voltage ratings of AC 240 V and AC 690 V.
Electrical Characteristics: Detailed characteristics are provided for each fuse size, including rated voltage, operating class, rated breaking capacity, power loss, pre-arcing, and total I2t-values.
Additional Features: The document outlines the availability of mounting clips and microswitches for indicator fuses, with specific part numbers and technical data.
Cut-Off and Time-Current Characteristics: Diagrams illustrate the virtual pre-arcing time and cut-off current peak against the RMS prospective current and prospective short circuit current, essential for understanding the fuse's behavior during fault conditions.
Additional Fuse Specifications: Details are provided for fuses with rated voltages of AC 690/700 V, with breaking capacities of 600 V/300 kA and 700 V/200 kA. Rated currents range from 32 A to 315 A, with detailed power loss and I2t-values.
Part Numbers and Accessories: Part numbers for various fuse-links and sets of clips are listed, including dimensions for indicator fuses and micro switches.
Notes: The document concludes with a section for additional notes, likely intended for further technical details or user instructions.
