Scada-Mate^® Switches and Scada-Mate CX™: Which Switch is Right for You?

The Scada-Mate Switching System has become the premiere solution for distribution automation applications, especially when provided with the IntelliTEAM II® Automated Restoration System. The Scada-Mate CX was designed in response to customer requests for a switch that is smaller, more modular—and thus more economical than the full-featured Scada-Mate Switching System. The Scada-Mate CX can also be tailored to meet specific application requirements, providing further economies.

View the tables below for a quick comparison of these two switching systems:
