Introduction
The S&C Scada-Mate CX™ Switching System is designed for outdoor distribution at 14.4 kV and 25 kV, suitable for remote supervisory control or automatic source transfer. It is a compact and expandable solution to meet evolving automation needs in overhead distribution systems.

Specifications
The Scada-Mate CX Switches are three-pole, group-operated interrupter switches rated at 900 amperes continuous and interrupting. They have a five-time duty-cycle fault-closing rating of 20,000 amperes RMS asymmetrical. Circuit operations occur within sealed interrupters in an SF6 environment, with a visible open/closed indicator.

Design and Features
The switches are factory-assembled on a one-piece base with an integral stored-energy operating mechanism. They offer both electrical and manual operation, with a lockable open position to prevent unintended closing. Available configurations include upright, upright with extra mounting-pole clearance, upright compact, and tiered-outboard models, all featuring S&C Cypoxy® Insulators.

Installation and Expandability
Scada-Mate CX Switches are designed for simple installation with permanent lifting means. They can be expanded with factory-installed or later-added sensors and control units. The system supports a range of control units, including the 5800 Series Automatic Switch Control for sophisticated automation and communication.

Optional Features
Optional features include a visible-break disconnect, arrester brackets, wildlife protection, and various control cable lengths. The visible-break disconnect is interlocked for safety and based on the Loadbuster Disconnect® design.

Performance and Ratings
The switches can endure 500 operations of loop-current switching at 900 amperes and have a 1-second rating of 16,000 amperes RMS symmetrical. They are available in various configurations with specific catalog numbers and ratings.

Conclusion
The S&C Scada-Mate CX™ Switching System offers a reliable and adaptable solution for automating overhead distribution systems, with options to meet diverse operational and environmental needs.
