T/CEEIA 509-2021 Intelligent Low-voltage Circuit Breaker
Basic Information
Scope
Scope: This document specifies the terms and definitions, classification, characteristics, product information, normal operation, installation and transportation conditions, structural and performance requirements, and test methods for intelligent low-voltage circuit breakers (hereinafter referred to as circuit breakers). This document applies to circuit breakers that comply with GB/T 14048.2—2020 "Low-Voltage Switchgear and Controlgear—Part 2: Circuit Breakers", and have functions such as electrical measurement and alarming, state sensing, diagnostic maintenance, and health status indication, as well as fault and historical recording. They can be locally and/or remotely monitored, and have the ability to connect directly or indirectly to the Internet of Things (IoT) cloud platform and meet network security requirements. This document proposes the communication connection methods, communication modes and protocols, and network security requirements for circuit breakers. Note: Intelligent low-voltage circuit breakers are also referred to as "Internet of Things circuit breakers", "IoT circuit breakers", or "IoT intelligent circuit breakers".
