Key Product Features

Self-Powered Reliability
Independent backup power supply maintains all critical control and protection functions during auxiliary power failure. Essential for remote, unmanned, and mission-critical installations such as data centers and primary and secondary distribution systems.
Integrated Metering Device and Loads Management
Built-in energy metering at the switching point eliminates the need for external metering panels. Enables precise energy measurement for accurate billing, load monitoring, and energy management at the distribution level, a key differentiator of the Special Use variant.
Smart Grid Architecture (IoT + Edge Control)
Delivers the three pillars of modern distribution: control, monitoring, and protection. IoT-enabled platform supports edge control, data analytics services, and advanced predictive monitoring of cable connection partial discharge for condition-based maintenance.
Motorized & Interlocked Operation
Fully motorized switching with reliable interlock mechanisms prevents mis-operation and ensures safety. Supports both manual and remote-electric actuation. IP54 enclosure enables direct outdoor deployment, reducing substation building requirements and conductor costs.

Proven Performance

Mission-Critical Reliability

Self-powered backup supply ensures uninterrupted control and protection across a 30-year maintenance-free lifecycle. Purpose-built for data centers, hospitals, primary substations, secondary substations, renewables, and industrial applications where operational continuity is non-negotiable.

Predictive Maintenance & Remote Visibility

IoT-enabled platform delivers predictive cable monitoring, data analytics, and edge control, reducing total cost of ownership through condition-based maintenance and enabling proactive digital asset management across the network lifecycle.

Decentralized Power Generation Ready

Handles fluctuating bidirectional power flows from solar and wind sources with reliable automated switching and real-time SCADA visibility, supporting stable smart grid and renewables cluster operation.

Compact Outdoor & Harsh Environment Rated

IP54 enclosure enables direct outdoor deployment without additional substation buildings. SF6 gas-insulated construction shields components from dust, moisture, corrosive gases, and contamination across coastal, industrial, and desert environments.
