1SDA054954R1 ABB - RC222/4 T4 4P F

The 1SDA054954R1 is an ABB RC222/4 T4 4p F residual current release, designed to enhance the safety and protection of electrical systems. This device is specifically engineered for use with T4 fixed four-pole circuit breakers with a current rating of 250A. As a Type-B residual current release, it offers advanced detection capabilities, responding to both AC and DC residual currents, as well as pulsating DC residual currents. This broader sensitivity makes it suitable for applications with electronic equipment that may generate DC fault currents. The RC222/4 provides reliable protection against earth faults and leakage currents, minimizing the risk of electrical shock and fire hazards. Its robust design ensures dependable performance in demanding industrial and commercial environments. By quickly interrupting the circuit upon detection of a fault, it prevents damage to equipment and reduces downtime. This residual current release is an essential component for ensuring compliance with safety standards and regulations. It contributes to a safer electrical installation by providing an extra layer of protection against potentially dangerous electrical faults.
