Yes. Rockwill 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.
Yes. Rockwill provides a comprehensive OEM/ODM program for the RCW series reclosers. 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.
