Product Overview

The composite switch -HRDQ-FS is mainly used in low-voltage reactive power compensation systems with an AC frequency of 50Hz to 60Hz and a rated voltage of 220V or 380V to connect and disconnect power capacitors.

Its main features are no inrush current during input, low energy consumption and no noise during operation, stability and reliability. The composite switch -HRDQ-FS is composed of three independent synchronous switches and is suitable for the on-off control of low-voltage reactive power compensation capacitor banks. The basic working principle of the composite switch -HRDQ-FS is to use a magnetic latcher relay. The composite switch -HRDQ-FS has the advantage of zero-crossing switching at the moment of connection and power-off, and during the normal connection period, it also has the advantage of no power consumption of the contactor switch.
