FAQ for outdoor vacuum recloser

Q: What are the key differences between Rockwill's RCW series recloser and a ZW32-type vacuum circuit breaker?

The ZW32-type VCB is a basic circuit breaker or demarcation switch without built-in auto-reclosing logic, whereas the RCW series is specifically engineered as a full-function recloser with integrated protection, sensors, and communication for smart grid applications.

Unlike the ZW32, which requires an external controller for automation, the RCW series complies with IEC 62271-111 and ANSI C37.60, and is supported by complete type test reports.With silicone rubber or epoxy insulation offering superior aging resistance and low water absorption, the RCW series is the professional choice for international distribution automation projects.

Q: Does Rockwill really provide a 10-year quality warranty and free replacement?

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.
