概览

KA2803B 适用于接地漏电流断路器，用于直接关断断路器中的交流线路。差分放大器的输入联接 ZCT（零电流变压器）的辅助线圈。差分放大器的放大输出集成在外部电容器处，以获取 KSC4613 中规定的充分时间延迟。当接地漏电流大于固定电平时，电平比较器则生成高电平。

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
