What does RCD mean?

[LeAthena]

RCD has the following meanings: 1. In building electrical systems: RCD refers to Residual-Current-Device, which primarily functions to prevent fires and equipment damage caused by leakage currents. 2. RCD also stands for Room Temperature Catalytic Decomposition: It involves the long-term stable catalytic oxidation of formaldehyde pollutants in the air into water and carbon dioxide using ambient heat at room temperature. The Residual-Current-Device (RCD) is a leakage protection device. Leakage protection devices are low-voltage safety protection appliances with the following functions: 1. Preventing single-phase electric shock accidents caused by leakage currents; 2. Preventing fires and equipment damage caused by leakage currents; 3. Detecting and interrupting various single-phase ground faults; 4. Some leakage protection devices can also provide overload, overvoltage, undervoltage, and phase-loss protection.
