The LW8 universal conversion switch is suitable for converting electrical control circuits and electrical measuring instruments in AC 50Hz, voltage up to 380V and below, and DC voltage up to 220V and below. It can also directly control small-capacity three-phase AC cage induction motors (2.2kW and 5.5kW). It complies with the GB14048.5-93 standard.
About this manual
The LW8 universal transform switch is designed for AC circuits up to 380 V (50 Hz) and DC circuits up to 220 V. It can be used to switch electrical control lines and measurement instruments, and it can directly start small‑capacity three‑phase cage induction motors (2.2 kW or 5.5 kW).\n\nThe manual lists the main technical parameters such as working voltage, current, insulation voltage, heating current, electrical and mechanical life, and operation frequency. It also describes the different switch types (self‑return and positioning) and their contact sections, as well as the dimensions and installation guidelines. This manual is written in Chinese.
