Note: When the current exceeds 10A, a heat sink is required. When the current exceeds 30A, a heat sink with a suitable heat dissipation area and air cooling or water cooling is required. Matching heat sinks B20~B80 are single-phase heat sinks; B140~B360 are three-phase heat sinks; B90 is a three-phase two-control heat sink.
