The ABB SPOC 110 C-AA Network Control & Protection Module is a control and measuring unit designed for medium-voltage switchgear automation and substation remote control applications. It provides an interface between switchgear equipment and higher-level control systems by collecting binary signals, processing measurement data, and transmitting control information through serial communication networks.

The SPOC 110 C-AA belongs to the ABB SPOC 100 Series control and measuring units. It is designed for cubicle-based remote control applications, supporting circuit breaker control, disconnector status monitoring, alarm signal acquisition, analog measurement, and communication with substation automation systems.

This module is commonly used in electrical distribution substations, switchgear panels, and industrial power systems where legacy ABB protection and control equipment remains in operation. The SPOC 110 C series has been discontinued as an active product and is maintained mainly through spare-part replacement channels.
