ABB SPAU110C Advanced Residual Overvoltage Relay, Ensuring Electrical Safety
The ABB SPAU110C is a protective relay designed for feeder protection in medium-voltage networks. Key specifications include adjustable overcurrent and earth-fault protection, with a wide setting range from 0.5 to 2.5 times the rated current. It features a user-friendly interface and supports multiple communication protocols like Modbus and IEC 60870-5-103. Typical applications include industrial power distribution and utility substations. Compared to the ABB SINT4510C, the SPAU110C offers more flexible settings but lacks the advanced fault recording capabilities of the SINT4510C.
