Fuses for semiconductor and line protection (URL)

Product catalog summary
Overview: The document provides comprehensive details on SIBA's range of fuses specifically designed for semiconductor protection, focusing on the gRL (gS) class. These fuses are engineered to deliver high current limitation, low power losses, and protection against short circuit faults and overload currents. They comply with standards such as IEC 60269-1/-2-1 and -4, DIN 43620-1, and DIN 43653.
Specifications:
  • Voltage Rating: AC 500-690 V
  • Current Rating: 6-800 A
  • High interrupting rating up to 200 kA
  • Low I2t-values for efficient protection
Types of Fuses:
Features and Benefits:
  • Combines characteristics of aR and gG fuse classes into gRL
  • Provides semiconductor protection with Ultra Rapid “gR” characteristic
  • Offers cable protection with “gG” characteristic
Selection Guides: Extensive selection guides are included for various fuse types, bases, clips, and micro switches, detailing part numbers, rated currents, weights, and packaging information. Technical data references for each product are also provided.
Compliance and Standards: The fuses adhere to international standards, ensuring reliability and safety in their application. They are suitable for use in power electronic equipment and cable protection systems.
Additional Specifications:
  • Fuse Sizes and Rated Voltages: Sizes include 10 x 38 mm, 14 x 51 mm, 22 x 58 mm, with rated voltages from AC 400 V to AC 700 V.
  • Standards: Compliance with IEC 60269-4 and UL 248-13.
  • Operating Class and Breaking Capacity: Most fuses are of type gRL(gS) with rated breaking capacities up to 200 kA.
Electrical Characteristics:
  • Rated Current and Power Loss: Detailed tables provide rated currents, power loss, pre-arcing, and total I2t-values for various fuses.
  • Time-Current and Cut-Off Characteristics: Graphs and diagrams illustrate the time-current characteristics and cut-off current peaks for different prospective short circuit currents.
Mounting and Dimensions:
  • PCB and Fixing Centers: Dimensions for PCB mounting and fixing centers are provided for different fuse sizes.
  • Fuse Base and Nut Torque: Specifications for fuse bases, including rated current, nut torque, and power acceptance, are detailed for DIN type SQB1, 2, and 3.
Additional Information:
  • Part Numbers: Each fuse type is associated with specific part numbers for easy identification.
  • URL References: The document includes multiple URLs for further reference and detailed product information.
