Three-Phase Automatic Recloser
Integrated casting ensures reliable insulation; permanent magnet mechanism provides fast and stable operation; precise fault identification and isolation comprehensively enhance distribution network power supply reliability.
Product Description
The HXD811 series three-phase recloser includes three models: HXD811-15, HXD811-27, and HXD811-38. A complete three-phase recloser system consists of the primary three-phase recloser switch and the secondary three-phase recloser controller. It is primarily used for fault identification, fault location, and fault isolation, thereby improving the power supply reliability of distribution network feeder lines. It has been widely applied. While similar to a pole-mounted circuit breaker with FTU, the key differences are that the three-phase recloser requires higher insulation performance, uses a permanent magnet mechanism that is simple and reliable, operates faster, has a longer mechanical lifespan, offers richer protection functions, and supports more communication protocols.
