Fibre optic interconnecting devices and passive components performance standard - Sealed closures for category A. Aerial Ingestion-build-132972 voltage-operated earth-leakage circuit-breakers having rated1 Scope This part of IEC 61753 contains the minimum test and measurement requirements and severities which a sealed fibre optic closure must satisfy in order to be categorised as meeting the IEC standard for category A aerial, as defined in Annex A of IEC 617531. Free breathing closures are not covered in this standard.
