Customization, ease of maintenance and enhanced safety.

Customization: standard design is highly flexible on bus arrangement, control power, relaying, and accessories.

Ease of maintenance: drawout vacuum breakers have up to 10,000 operations, drawout instrument transformers, and isolated low voltage compartment.

Enhanced safety: fully compartmentalized construction, grounded barriers, mechanical interlocks, breaker shutters, and fully insulated bus keep operators segregated from medium voltage. Remote breaker racking is an available option. Active arc extinguishing system is also an available option.

Critical main service entrance protection and control for large installations including industrial plants, buildings, data centers, hospitals, utility generation systems, and water/wastewater plants.
