1SDA054956R1 ABB - RC223/4 T4 250 4P F

The 1SDA054956R1 is an ABB RC223/4 residual current release designed for reliable protection against electrical faults. Specifically engineered for use with T4 250 fixed four-pole circuit breakers, this device offers advanced functionality and enhanced safety. Featuring Type-B residual current protection, it is sensitive to a wide range of fault currents, including AC, DC, and pulsating DC components. This ensures comprehensive protection in various applications. The RC223/4 module continuously monitors the current balance in the circuit, and it swiftly trips the circuit breaker upon detecting a residual current exceeding the set threshold. This rapid response minimizes the risk of electrical shock and prevents potential damage to equipment. Its robust design and high-quality components ensure long-term reliability and consistent performance. Suitable for industrial, commercial, and residential settings, the RC223/4 provides a critical layer of protection against electrical hazards. This residual current release is easy to install and integrate with existing T4 250 circuit breaker systems, making it a convenient and effective safety solution. By preventing electrical accidents and equipment damage, the ABB RC223/4 significantly contributes to a safer and more reliable electrical environment.
