The RCW series automatic vacuum circuit reclosers can use on overhead distribution lines as well as distribution substation applications for allvoltage classes 11kV up to 38kV at 50/60Hz power system. and it’s rated current can reach 1250A.
The RCW series automatic circuit reclosers integrates the functions of control, protection, measurement, communication, fault detection, on-line monitoring of closing or opening.The RCW series vacuum recloser is mainly combined with integration terminal, current transformer, permanent magnetic actuator and it’s recloser controller.
Optional grades available in rated current range.
With optional relay protection and logic for user selection.
With optional communication protocols and I/O ports for users to choose.
PC software for controller testing, setup, programming, updates.
Mobile APP software supports GPRS / GSM / WIFI / Bluetooth communication.It provides map guide & location function, protection setting & modification, as well as monitoring & controlling. It enables operators to debug, inspect and maintain the recloser both on‑site and remotely.
The epoxy pole is integrally formed by APG process. The vacuum interrupter is encapsulated inside epoxy resin with compact insulation. Designed with sheds for higher creepage distance, it resists dust and salt‑spray, and passes PD & HV tests to guarantee reliable recloser operation.

Yes, Rockwill provides a comprehensive OEM/ODM program for our RCW MV Single-phase vacuum recloser.
We partner exclusively with regional manufacturers and distributors who possess robust engineering expertise and local service capabilities, ensuring they can deliver outstanding technical support alongside our advanced technology.
While the ZW32 is a basic switch requiring an external controller, the RCW MV Single-phase vacuum recloser is a fully integrated smart grid solution with built-in protection, sensors, and communication.
Furthermore, it strictly complies with IEC/ANSI standards and uses premium insulation designed specifically for international distribution automation projects.
The Rockwill standard smart recloser offers high precision with a wide measuring range (2A–16,000A). Simply ensure your normal current is within this standard range when making a selection.
Yes. In addition to the standard 2A–16,000A range, Rockwill provides custom-configured units for ultra-low current measurement and protection in the 0.1A–2A range.
