1、 Scope of application
Mainly used in power lines with AC frequency of 50Hz or 60Hz and rated working voltage up to 380V, for the input or disconnection of low-voltage reactive power compensation equipment and low-voltage parallel capacitors. The contactor is equipped with surge suppression devices, which can effectively reduce the impact of closing surge on capacitors and suppress overvoltage during opening and closing.
2、 Model and meaning

Basic Parameters
structural characteristics
1. The contactor is equipped with a current limiting resistor, which can suppress the inrush current during closing within the allowable range.
2. The contactor book adopts a direct acting double break structure, with flexible action mechanism and manual mechanism, convenient manual inspection, compact structure, and easy replacement of contacts.
3. The insulation cover of the contactor terminal book ensures safety and reliability.
4. Installation can be fastened with screws, or standard installation rails with a diameter of 35mm or 75mm can be fastened to the vehicle rail book.
