Product details: SPAJ140C ABB combination overcurrent and ground fault relay

SPAJ140C is a powerful, highly integrated, and flexible combination overcurrent and ground fault relay produced by ABB. It is widely used for short-circuit and ground fault protection in power systems, with high reliability and stability. For users who need efficient and reliable power protection solutions, SPAJ140C is undoubtedly an ideal choice.

Overcurrent protection function:
A three-phase low setting phase overcurrent device with timed or inverse minimum time (IDMT) characteristics.
A three-phase high setting phase overcurrent device with instantaneous or timed characteristics.
When a fault is detected, it will start, trip the circuit breaker, provide alarm signals, and record fault data according to application requirements and relay configuration.
Ground fault protection function:
Low level grounding fault device with timed or inverse minimum time (IDMT) characteristics.
High level grounding fault unit with instantaneous or definite time operation function.
When the ground fault current exceeds the set value, it will start and send a start signal for ground fault protection.
Other features:
Built in circuit breaker fault protection.
Two overload relays and four signal output relays, the output relay matrix can route the start or trip signals of the protection level to the required output relays.
Local display of measured values, set values, and data recorded during faults.
The self-monitoring system can continuously monitor the operation of electronic devices and microprocessors.
Product details and parameters: SPAJ140C ABB combination overcurrent and ground fault relay
Highly integrated: It integrates overcurrent protection and ground fault protection functions, reducing the number of devices and footprint.
Flexible configuration: It can be flexibly configured according to application requirements to meet protection requirements in different situations.
High reliability: Adopting advanced microprocessor technology and powerful software support, ensuring the high reliability and stability of relays.
Easy to maintain: By using the local display screen and front panel buttons or the serial interface of the superior system and fiber optic bus to read and write set values, it is convenient for users to set parameters and diagnose faults.

SPAJ140C ABB backup application areas:

The SPAJ140C combined overcurrent and ground fault relay is widely used for selective short-circuit and ground fault protection of radial feeders in solid grounded, resistance grounded, or impedance grounded power systems. Meanwhile, it can also be used in other applications that require single-phase, two-phase, or three-phase overcurrent protection.
