Weidmueller TR BD AITB RCD W/O TS

TR BD AITB RCD W/O TS refers to an electrical distribution board that combines an Automatic Insertion Type Breaker (AITB) with a Residual Current Device (RCD) for overcurrent and leakage current protection. The "W/O TS" stands for "Without Test Switch," meaning the RCD does not include a built-in test switch to manually check its functionality. This configuration is commonly used in electrical systems where RCD protection is needed, but the test switch feature is not required, typically found in residential, commercial, or industrial applications.
