This 27kV‑38kV pole‑mounted Automatic Circuit Recloser (ACR) delivers reliable protection and switching control for outdoor overhead distribution lines. Adopting magnetic actuator and vacuum arc‑extinguishing technology, it uses one single magnetic actuator to drive three‑phase vacuum interrupters synchronously, with fewer mechanical failure points, higher stability and longer service life.
The vacuum interrupters are integrally encapsulated in hydrophobic epoxy resin housing, featuring high dielectric strength, anti‑pollution and hydrophobic performance for harsh outdoor conditions. Housed inside a corrosion‑resistant powder‑coated tank, the magnetic actuator and transmission components can withstand high humidity, heavy pollution and extreme temperatures for long‑term maintenance‑free operation.
The Microprocessor based controller provides protection, control, monitoring, instrumentation and metering with integrated input and output logic, data logging & fault report.Communication functionality of the controller is achieved via electrical RS485 port for remote connection. Additional rear ports including RS232 are available for selection.
The Feeder Terminal Unit(FTU) is the core of controller. To prevent any damage to FTU from emergency, the control cubicle contains auxiliary power supply of batteries for uninterruptible power supply, electronic boards and circuit breakers.
A series of protection functions can be set via screen display.

Yes. Rockwill vacuum recloser stands behind the RCW series with one of the most comprehensive warranties in the recloser industry: a full 10-year warranty covering the complete recloser, including the vacuum interrupter, permanent magnet operating mechanism, and control electronics.
Any failure resulting from material or manufacturing defects during the warranty period is eligible for free replacement. Our warranty terms are straightforward and transparent, with no hidden conditions or complex exclusions, giving you complete peace of mind.
Two types: magnetic actuator (M/G, mechanical life 30000 times) and spring mechanism (N, mechanical life 10000 times). Magnetic type can add manual closing function with code “C”.
Yes, both single‑phase and three‑phase reclosers are available. It can be installed on single/double poles for overhead lines or inside distribution substations.
It integrates control, overcurrent protection, measurement, communication, fault detection and online opening‑closing monitoring, matched with dedicated recloser controller.
