Fuse protection selection guide

Product catalog summary

Overview: This document serves as a comprehensive guide for selecting fuse protection, focusing on cylindrical and NH knife fuses. It includes specifications, standards, and recommendations for various fuse types and their applications.

Cylindrical Fuses: The guide details cylindrical fuses in sizes 00 to 2, with specifications for gG, aM, and gPV curves. Key parameters include current ratings (In), voltage (V), and breaking capacity (kA). Fuses are available with or without indicators, and are designed according to IEC 60269 standards.

Fuseholders: Information on cylindrical fuseholders is provided, covering sizes 00 to 2 with different pole configurations. The guide specifies the reference numbers, packaging details, and weight for each type.

NH Knife Fuses: The document outlines NH knife fuses with gG and aM curves, detailing current ratings, voltage, and reference numbers for sizes NH00 to NH3. It also includes NH fuse bases and switch disconnectors, specifying dimensions and configurations.

Ultraquick Fuses: These fuses are designed for semiconductor protection, with a rated voltage of 690VAC and 440VDC. They offer high current limitation and short-circuit breaking capacity, featuring a steatite ceramic body for temperature stress resistance.

Dimensions and Specifications: Detailed dimensions for various fuse sizes and configurations are provided, including NH fuse bases and switch disconnectors. The document includes tables and diagrams to illustrate the physical characteristics of the fuses and holders.

Key Recommendations: The guide emphasizes selecting the appropriate fuse type based on application requirements, considering factors such as current rating, voltage, and breaking capacity. It also highlights the importance of using fuses with indicators for easy status monitoring.
