GB/T 22200.5-2025 Reliability of low-voltage apparatus—Part 5:Reliability test method of residual current operated circuit-breaker for household and similar uses
Basic Information
Scope
This document specifies the reliability indicators, reliability test methods, reliability verification test plans and procedures, test records, and reliability test methods and steps under live operation for residual current operated circuit breakers (hereinafter referred to as "residual current operated circuit breakers") for household and similar applications.
This document applies to reliability test methods in accordance with GB/T 16916.1 or GB/T 16917.1, and is suitable for residual current operated circuit breakers with overcurrent protection or without overcurrent protection for household and similar applications, which comply with the requirements of AC 50 Hz, 60 Hz or 50 Hz/60 Hz, with a rated voltage not exceeding 440 V, a rated current not exceeding 125 A, and a rated short-circuit capacity not exceeding 25,000 A. The operation function is independent of or related to the power supply voltage. For residual current operated circuit breakers that comply with standards such as GB/T 14048.2, the reliability grade and test methods refer to the relevant content of this document.
