05 标准规范
本开关及同时提供的辅助设备和特殊工具符合供货 时所涉及的法律、条例及标准。
一符合标准 IEC-60056.
电 压 高 于 1kV 的交流开关设备标准-VDE0670 第101-108 部分。
实际技术数据将以供货时的铬牌数据和所附技
术文件为准。
10 工作温度
本开关工作所适用的环流温度范围为
30°C-+55°C
The 3AP1 circuit-breaker is of the self-compression type and uses SF6-gas for insulation and arc-quench- ing purposes, It is of triple-pole outdoor design.
The breaker has for all three phases a common operat- ing mechanism and is therefore suitable for triple-polar auto-reclosing.
05 Standard specifications
The circuit-breaker, together with the equipment and special tools also supplied, is in conformity with the statutory laws, rules and standards applying at the time of delivery.
-The specifications in IEC-Publications 60056.
The regulations for AC switchgear for voltages over 1 kV-VDE 0670 Part 101 to Part 108.
The technical data actually applying to the switching device supplied are stated on the rating plate and in the appended documentation.
10 Operating temperatures
The circuit-breakers are designed for operation in an ambient temperature range from-30C to+55 ℃.
