Reduce maintenance costs and downtime with reliable vacuum technology. Most power circuit breakers require maintenance and lubrication every two years and proper maintenance can require 6–8 man-hours per circuit breaker. Thanks to our advanced lubrication system that creates a protective layer between wearing surfaces, we have taken maintenance intervals to the next level. Coupled with our utility hardened mechanism and applied in normal applications as defined by IEEE Std C37.04™-1999, the VR-Series+ circuit breaker will only require maintenance once every 10 years or 10,000 operations, whichever comes first. Both the mechanism and control components can be easily maintained and can take as little as an hour to service.
Solve parts availability issues
Replacement parts for old air-magnetic circuit breakers are becoming harder to find and may not comply with the original manufacturer’s specifications. VR-Series+ mechanism and control components are compatible with Eaton’s VCP-W and VR-Series+ circuit breakers and are current production items. This means that replacement parts are in stock and available, saving you time and money, should you ever need them. Additionally, spare parts inventory is considerably reduced because VR-Series+ circuits breakers have 50% fewer parts than traditional air magnetic circuit breakers.
Increased interrupting capability
Power demands may have increased your available short current beyond your existing switchgear’s capabilities. VR-Series+ circuit breakers along with the appropriate bus bracing upgrades can increase your switchgear’s interrupting capabilities in the same space as your original air-magnetic circuit breakers. This provides a cost-effective alternative to a complete switchgear replacement.
Eliminate arc chutes
Arc chutes degrade with usage and must eventually be replaced. VR-Series+ circuit breakers use sealed vacuum interrupters and do not require arc chutes. Arc chutes raise environmental and legal issues due to asbestos.
Designed and tested to exceed current IEEE/ANSI standards
All VR-Series+ medium-voltage circuit breakers are designed and tested to meet or exceed IEEE/ ANSI C37.59™-2018 standards. This assures compatibility with existing installations and IEEE/ ANSI application guidelines. IEEE/ANSI certification and certified factory production test reports are available.
