SPAJ115C-DA ABB

Description

Product name  : SPAJ115C-DA  ABB Programmable controller

Product details:

The ABB SPAJ115C-DA is a combined restricted earth-fault and residual earth-fault relay. It’s designed to protect electrical systems and equipment from earth faults, which are unintentional connections between a live conductor and the earth. These faults can be hazardous and cause damage to equipment if not detected and cleared quickly.   

Key Features and Benefits

• Combined Protection: The SPAJ115C-DA offers both restricted earth-fault (REF) and residual earth-fault (REF) protection in a single device. This provides comprehensive protection against various types of earth faults.  

• High Sensitivity: The relay is designed to detect even small earth fault currents, ensuring rapid response and minimizing the risk of damage.

• Fast Tripping Time: When an earth fault is detected, the relay quickly trips the circuit breaker, isolating the faulty section and preventing further damage.

• Versatile Application: The SPAJ115C-DA can be used in a variety of applications, including:

  • Power transformers
  • Generators
  • Motors
  • Switchgear
  • Cables

• Easy to Use: The relay is designed for ease of installation, configuration, and operation.

• Reliable Performance: ABB is a trusted name in electrical protection, and the SPAJ115C-DA is built to provide reliable performance in demanding environments.
