RCDTeil

RCDTeil is a term used in German-speaking electrical engineering literature to denote a component or subassembly within a residual-current device (RCD). The exact scope of the term is not standardized and can vary depending on the manufacturer or documentation. In general, a RCDTeil refers to a discrete element that contributes to the protection function or installation of an RCD, rather than the complete device itself.

In RCD systems, the core function is to monitor the balance between live and neutral conductors and to disconnect the circuit when an imbalance indicating leakage current is detected. RCDTeil components may include the sensing element (often a toroidal current transformer or solid-state sensor), the tripping mechanism (electromagnetic or electronic), auxiliary electronics (microcontroller, diagnostics), and mounting or connection hardware.

Applications: RCDTeil is used in residential, commercial, and industrial electrical installations as part of protection against electric shock and fire caused by insulation leakage. In modular or retrofit designs, RCDTeil parts allow replacement or upgrading of specific functions without replacing the entire device.

Standards: RCDs and their parts are typically specified to international standards such as IEC 61008 (electrical safety, RCCBs) and IEC 61009 (RCBOs), with national implementations in VDE, DIN EN, and other regional standards. Any RCDTeil accompanying an RCD would be expected to conform to applicable safety and performance requirements.
