ABB SPAJ 110C digital power protection relay

The ABB SPAJ 110C is a reliable digital power protection relay designed to protect medium and high voltage power systems. It has a wide range of application fields and can meet the needs of various applications.

The SPAJ 110C's design features a combination of time-delay trip ground overcurrent (51G) and instantaneous trip ground overcurrent (50G) protection, making it more flexible and effective in protecting circuits. This protection method makes the SPAJ 110C especially suitable for the neutral point grounding protection of the secondary side Y connection of the transformer and the neutral point grounding protection of the secondary side Y connection of the motor.

In addition, the SPAJ 110C also has a variety of protection functions, including overcurrent, overload, ground fault, short circuit, undervoltage, etc., which can effectively protect the circuit from overload, short circuit and other faults. It supports a variety of communication interfaces, including RS-232 serial ports, gigabit network ports, etc., to facilitate connection and data exchange with other devices.

In terms of hardware specifications, the SPAJ 110C has a dual-core 4-thread processor, supports 8GB of memory and an MSATA hard drive, which can meet high data processing and storage requirements. At the same time, it also has a wide temperature working capacity, the temperature range of -40℃ to +80℃, suitable for a variety of harsh working environments.

Overall, the ABB SPAJ 110C is a powerful and stable power protection relay for the protection and control of a wide range of medium and high voltage power systems.
