IEC TS 63107:2020

IEC TS 63107:2020 provides technical guidance for the integration of internal arc-fault mitigation systems in power switchgear and controlgear assemblies (PSC-Assemblies) according to IEC 61439-2. It is relevant for engineers and compliance teams evaluating how arc-fault mitigation concepts are incorporated into low-voltage assemblies without compromising expected assembly performance or safety objectives. For organizations managing technical documentation, conformity assessment, or procurement review, IEC TS 63107:2020 supports a more structured understanding of design intent, verification activities, and risk management around internal arc-fault mitigation.

IEC TS 63107:2020 standard overview

This technical specification is intended to support the integration of internal arc-fault mitigation systems within PSC-Assemblies, with the broader framework of IEC 61439-2 in view. Its likely purpose is to help clarify engineering expectations for how mitigation functions are considered during design, verification, and technical assessment of assemblies. In practice, it can be used as a compliance reference when documenting safety-related design decisions, reviewing protective measures, or aligning product evaluation and test planning with assembly-level requirements.

Applications of IEC TS 63107:2020

IEC TS 63107:2020 is most applicable in the development, specification, and verification of low-voltage switchgear and controlgear assemblies where internal arc-fault mitigation is part of the design strategy. It may be used by manufacturers, test laboratories, project engineers, and procurement teams involved in technical validation, conformity assessment, or quality workflows for electrical equipment. The document is also relevant during tender preparation, product evaluation, and technical review where safety functions, assembly integration, and documented evaluation need to be aligned.

Why IEC TS 63107:2020 matters

This technical document matters because it helps organizations apply a consistent approach to arc-fault mitigation in PSC-Assemblies, which can support safety, interoperability, and operational consistency. It is useful for reducing ambiguity in engineering documentation, strengthening verification activities, and improving the traceability of compliance decisions. For procurement and certification workflows, it can also provide a clearer basis for comparing products, preparing conformity assessment evidence, and managing technical risk during deployment or acceptance testing.
