• Ground-level reset: Safely restore power after a lockout with a hot stick, minimizing exposure to arc flash and other hazards.
• Enhanced safety: Visible break, secure latching and guided closure ensure safe operation during linework.
• Rapid fault identification: Flashing beacon and wide-angle semaphore make locating tripped units fast and intuitive.
• Grid reliability: Automatically clears temporary faults and isolates permanent ones to reduce outage duration and crew deployment.

• Three configurable modes of operation: A programmable electronic control allows for application versatility with multiple operational settings.
• Single-phase trip lockout: If a permanent fault occurs on one phase, that phase will lock out and the other two phases will trip open, preventing damaging “single-phasing” conditions for three-phase motor loads.
• Three-phase lockout: All three phases trip and reclose simultaneously.
• Enhanced system reliability: By isolating only the faulted phase for most temporary faults, triple-single operation can significantly improve utility reliability indices.

• Air-insulated dead-front design: The internal components are insulated using air and dead-front connectors within a sealed switching compartment, minimizing exposure to energized parts.
• Enhanced safety: The dead-front design, external operator and visible break windows reduce the risk of electrical exposure for utility workers and the public.
• Reduced maintenance: Constructed from heavy-gauge steel with corrosion-resistant coatings and compatible with multiple pad configurations.
• Operational efficiency: Large viewing windows, replaceable bushings and external operators streamline maintenance and fault identification.

• Solid dielectric technology: Vacuum interrupters encapsulated in hydrophobic cycloaliphatic epoxy (HCEP) material.
• Integrated sensing: Standard switches include three voltage sensors and three current sensors for advanced monitoring and control.
• Manual operation and lockout: Manual operating handle with hookstick use and a mechanical blocking mechanism to prevent unintended closure.
• Integrated solution: Controllers, cables and switching devices assembled, configured, integrated and tested to meet your needs.

• Optimize power quality: Supplies the reactive power needed by inductive loads, bringing the voltage and current waveforms closer together for greater system efficiency.
• Pre-wired and pre-configured: Designed for rapid installation with one standard package, making ordering straightforward.
• Reliable performance: Stabilizes voltage levels within the distribution system, helping maintain reliable equipment performance.
• Grid efficiency: Minimizes reactive power flows, reducing resistive energy losses in transmission and distribution lines.

• Enhanced safety: Containing electrical connections within a protective enclosure minimizes risk of electric shock, accidental contact with live wires, and short circuits.
• Secure and organized: Built-in terminal blocks, rails and cable management features keep wiring neat and structured.
• Protection from elements: Durable fiberglass, steel or aluminum construction protects components from dust, moisture and impact.
• Easier maintenance and troubleshooting: Organized layout and easy access points simplify fault identification and repair, reducing downtime.
