As distribution networks become increasingly automated, utilities require more than a conventional circuit breaker—they need intelligent equipment capable of detecting, analyzing, isolating, and restoring faults automatically. Our 33KV Vacuum Circuit Breaker With Recloser is specifically developed for smart distribution systems, combining high-performance vacuum interruption with advanced protection, fault analysis, and automatic reclosing technology. It is widely deployed in utility substations, overhead distribution feeders, renewable energy collection systems, mining facilities, industrial parks, and rural electrification projects where network reliability directly affects operational efficiency.
Built upon the proven interruption platform of our 33KV Vacuum Circuit Breaker, this intelligent solution integrates the automation capabilities of an Automatic Reclosing Circuit Breaker while sharing the rugged outdoor construction of our Outdoor Recloser Circuit Breaker. For utilities seeking a complete pole-mounted automation solution, it also complements the 33KV Outdoor Recloser Circuit Breaker product family. Together, these technologies help reduce outage duration, improve SAIDI/SAIFI performance, and lower maintenance costs across the distribution network.
Unlike conventional circuit breakers that simply disconnect faulted feeders, this equipment continuously monitors electrical parameters including phase current, voltage, power quality, and fault history. The intelligent controller automatically determines whether a disturbance is temporary or permanent before executing programmable reclosing sequences. Temporary faults caused by lightning, tree branches, wildlife, or contamination are restored automatically, while permanent faults remain isolated to minimize the impact on healthy sections of the network.

A standard vacuum circuit breaker only interrupts fault current, while a recloser-equipped model automatically attempts to restore power after temporary faults through programmable reclosing sequences, improving feeder reliability and reducing outage duration.
It is ideal for utility distribution feeders, rural electrification projects, renewable energy substations, industrial distribution systems, mining operations, airports, railways, and smart grid automation projects.
Yes. The controller supports IEC 61850, DNP3, Modbus RTU/TCP, and IEC60870-5-101/104, allowing straightforward integration with most utility automation platforms.
Yes. Utilities can configure protection curves, reclosing attempts, dead times, lockout logic, coordination settings, communication parameters, and event recording functions according to their protection philosophy.
The sealed vacuum interrupter is maintenance-free. Periodic inspections mainly involve checking mechanical components, controller status, battery health, and communication functions, resulting in significantly lower maintenance costs than conventional switchgear.
