Description

  • The ABB 1SDA051400R1 Circuit Breakers RESIDUAL CURRENT RELEASE is a critical accessory designed to enhance the functionality and safety features of ABB circuit breakers with a fixed three-pole configuration, specifically those designated as "T1" models. This residual current release, often referred to as an RCD (Residual Current Device) or RCCB (Residual Current Circuit Breaker), plays a pivotal role in protecting electrical circuits and ensuring the safety of personnel and equipment.


  • The primary functions of this residual current release is to detect and respond to imbalances in the electrical current flowing through the circuit. It is specially designed to monitor the difference between the current entering the circuit and the current returning from it, commonly referred to as the residual current. This capability is crucial for identifying ground faults, which can occur when electrical current unintentionally flows to ground through unintended pathways, such as a person touching a live conductor.


  • The ABB 1SDA051400R1 residual current release takes prompt action. It rapidly disconnects power by tripping the associated circuit breaker, effectively isolating the affected circuit and preventing electrical shocks, fires, or equipment damage. This quick response is essential for ensuring the safety of both individuals and property in electrical installations.
