About This Item
C37.48.1-2011 is a technical standard for voltage above 1000 V current-limiting fuses, presented as a redline edition for easier review of changes. It supports engineers and purchasers working with power, energy, and industrial applications where fuse performance, interruption behavior, and system protection must be carefully specified. For high-voltage equipment, this standard helps define expectations that can improve selection, documentation, and compliance decisions.
What is C37.48.1-2011?
C37.48.1-2011 addresses the requirements and technical context for current-limiting fuses used in circuits above 1000 V. As a redline document, it is intended to show revisions against a prior edition, which can help users understand what changed in the specification. The standard is relevant to product development, engineering review, and procurement where fuse ratings, protective behavior, and consistent terminology matter in high-voltage power systems.
Where is C37.48.1-2011 used?
This standard is typically used in high-voltage power distribution and industrial electrical equipment that relies on current-limiting fuses for protection. It may apply to switchgear, fused interrupter assemblies, transformers, capacitor banks, and related apparatus in utility or plant environments. Because the subject includes components, circuits, devices, and systems, C37.48.1-2011 is useful where fuse selection, installation, and coordination need to align with the surrounding electrical design.
Why is C37.48.1-2011 important?
C37.48.1-2011 matters because fuse specifications affect safety, interruption capability, and system coordination in higher-voltage applications. Using a clear standard helps reduce ambiguity during design, testing, and procurement, especially when comparing products or documenting compliance. A redline version is also valuable for tracking revisions, since engineers and specifiers can quickly identify updates that may influence performance expectations, interchangeability, or acceptance criteria for a protection scheme.
