2. Functional Highlights

Combined protection: Provides over-current and earth-fault protection within a single device, simplifying switchgear panel layout.

Flexible time-current characteristics: Supports definite-time, inverse-time (IDMT), and instantaneous curves with customizable settings based on system requirements.

High reliability: MTBF over 20 years, with self-supervision for real-time monitoring of hardware and software status.

Local and remote access: Equipped with local display/buttons and supports serial/optical communication for centralized monitoring and remote diagnostics.

Compatibility: Supports ABB’s PYRAMID™ coordinated protection philosophy and integrates seamlessly with other ABB distribution automation products.

3. Typical Application Scenarios

Distribution feeder protection: Provides selective short-circuit and earth-fault protection for distribution systems with solid, resistance, or impedance grounding.

Industrial facility power distribution: Used in switchgear for large industrial plants to ensure reliable over-current and earth-fault protection.

Building automation: Ensures safe and reliable protection in commercial buildings and residential complexes.

Power system upgrades: Replaces standalone over-current or earth-fault relays in legacy systems to achieve functional integration and system simplification.

Conclusion

The ABB SPAJ140 series is a highly integrated, flexible, and reliable combined over-current and earth-fault relay, suitable for a wide range of distribution automation applications.
