IV. Classification
1. According to the installation mode: Fixed type, draw-out type.
2. According to the operation mode: Electrical operation, manual operation (for overhaul and maintenance).
3. According to the number of poles: 3 poles, 4 poles.
4. According to the release type: Intelligent release, undervoltage instantaneous (or delay) release, shunt release.
5. According to the performance of the intelligent overcurrent controller: Mic5.0 (intelligent), Mic2.0 (multifunctional), Mic1.0 (standard). The
functions of the three types of controllers are shown in Table 1.
