Bold-type fuses (URB)

Product catalog summary
Overview
This document outlines the technical specifications and selection guidelines for fuses used in semiconductor protection, specifically focusing on European Standard Sizes 000 and 00. These fuses fall under class aR and are designed for voltage ratings between AC 660 V and AC 1000 V, with current ratings from 16 A to 400 A. They adhere to standards such as DIN 43653, IEC 60269-1 and -4, DIN VDE 0636-40, and UL 248-13.
Specifications
  • Voltage Ratings: AC 660 V to AC 1000 V
  • Current Ratings: 16 A to 400 A
  • Interrupting Rating: Extremely high, ranging from 100 kA to 300 kA
  • Standards Compliance: IEC 60269-1 and -4, DIN 43653, DIN VDE 0636-40, UL 248-13
  • Features: Options for top indicator and trip microswitch; available fuse-bases and accessories.
Selection Guide
The document provides a comprehensive selection guide for various fuse sizes and configurations, detailing rated voltage, fixing center, indicator options, and part numbers. For instance, size 000 fuses are available for AC 660 V and AC 690/700 V with options for top indicators or micro switch fittings.
Electrical Characteristics
Detailed electrical characteristics are provided for each fuse size, including:
  • Rated Voltage and Operating Class: Size 000 fuses have a rated voltage of AC 660 V and an operating class of aR with a breaking capacity of 100 kA.
  • Power Loss and I2t-values: Specific power loss and pre-arcing I2t-values are detailed for each current rating.
Dimensional Specifications
Dimensional details for each fuse size are included, such as length, width, and maximum dimensions.
Performance Data
Performance data for micro switches is included, covering:
  • Current with and without Top Indicator
  • I2t-values at 1000 V for various current ratings (e.g., 32 A, 40 A, 50 A, etc.)
Additional Components
Information on additional components like hammers and terminals is provided:
  • Part Numbers: 28 002 01 (Black Hammer), 28 002 02 (Red Hammer)
  • Interrupting Rating: AC 250 V, DC 33 V
  • Terminals: AMP 2.8 x 0.5 (IEC 760)
Notes
The document includes notes on the use of articles and their weight, as well as the rated voltage for GL-Switch AC 250 V for fuse-links with gripping lugs.
