The feeder terminal type SPAC 331 C is used as a cubicle-oriented protection and remote control unit. In addition to protection, control and measurement functions, the feeder terminals are provided with the data communication facilities needed for the control of a feeder cubicle. Connection to higher-level substation control equipment is carried out via a fibre-optical serial bus.
The feeder terminal SPAC 331 C is part of ABB’s Distribution Automation concept.
If sensitive earth-fault protection is not required, the feeder terminal type SPAC 330 C is recommended.
