T/JCBD 003-2022 Plastic Enclosed Circuit Breaker with Internet of Things Functionality
T/JCBD 003-2022
Basic Information
Scope
Main technical content: This standard specifies the terms, definitions, and symbols, classification, basic requirements, characteristics, normal use, installation conditions, structure and technical requirements, testing, inspection rules, marking, packaging, transportation and storage, and quality commitments of plastic circuit breakers with Internet of Things (IoT) functionality. The standard applies to AC 50Hz, with a rated insulation voltage of 800V, a rated working voltage of 400V/690V, and a rated working current of up to 630A. The plastic circuit breakers with IoT functionality are used to protect against ground faults, overcurrent, short circuits, overvoltage, undervoltage, automatic tripping in case of power failure, and phase loss in circuits or electrical equipment. They are suitable for normal use and installation conditions, and are also applicable to plastic circuit breakers with IoT functionality that have a protection grade higher than IP30 and are used in more severe environmental conditions and high-altitude areas.
