Description

Pioneer of China’s recloser track and the first specialized source manufacturer — that’s who we are after decades of focused efforts. We’ve strengthened our foundation via tech breakthroughs, guided the industry through standard-setting, and built a fully independent full-chain system from core R&D to mass production and delivery.We are an Automatic Recloser China Factory, supporting both standard and customized production for global customers.

The RCW series automatic circuit reclosers can be used on overhead distribution lines as well as in distribution substation applications for 15 kV voltage class in 50/60 Hz power systems, and its 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 composed of integrated terminal, current transformer, permanent magnetic actuator and its recloser controller.

FAQ for Auto Circuit Recloser

Does Rockwill offer a cost-effective alternative that is more budget-friendly than the standard RCW+ series?

Yes. The RCWP, a cost-optimized option in the RCW+ series, features dual sensors, flagship controller, and 30,000 operations with permanent magnet three-phase linkage, while offering downgrade options (lock box removal, lockout removal, sensor/controller downgrade) so customers pay only for what they need.

Does Rockwill Vacuum Recloser really provide a 10-year quality warranty and free replacement?

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.

Does Rockwill vacuum recloser provide OEM/ODM services for local partners and regional manufacturers?

Yes. Rockwill provides a comprehensive OEM/ODM program for the RCW vacuum recloser. However, we are very selective in our partner selection — we specifically seek manufacturers and local partners with strong technical capabilities, solid engineering background, and local service capacity. Our goal is to partner with entities that can not only distribute but also provide local technical support to promote our advanced technology.

How to select current sensor or current transformer specifications for Rockwill Smart Recloser?

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.

Does Rockwill offer an MV Smart Auto Recloser capable of measuring primary currents as low as 0.1A?

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.
