- Comprehensive range of three phase vacuum reclosers with mechanically ganged operations. Suitable for overhead distribution lines up to 38kV.
- Compliance to IEC62271 - 111 / IEEE C37.60
- SmartOn circuit reclosers can drastically reduce the SAIDI/SAIFI on overhead networks with impressive ROI. Reduces the downtime due to temporary faults by 90%.
- With effective deployment in coordination with Sharika’s range of Smart LBS, Smart FIDs and FPIs, the solution can help manage complex meshed networks, where protection coordination on secondary networks is otherwise impossible.
- Comprehensive protection and control elements help customers substantially improve network and substation performance.
- With technical collaboration with S. Korea, Sharika presents customizable switchgear options to suit different applications and budgets.
- Choose between motorized or magnetic actuators, 12.5kA to 25kA interruption capabilities, and from simple current-based protections to advanced protection modules.
- For large remote deployments, Sharika offers industry-first advanced lithium batteries with built-in BMS.
- Sharika is likely the only OEM offering custom-built MV switchgear to meet evolving customer needs.
