A 3mA RCD (Residual Current Device) is a type of safety device designed to detect and disconnect electrical circuits in the event of a leakage current of 3 milliamperes or more. It provides protection against electric shock and reduces the risk of electrical fires by quickly interrupting the power supply when it detects an imbalance between the live and neutral currents. These devices are often used in sensitive applications, such as in medical facilities or outdoor settings, where enhanced safety is crucial.
No, the 30 mA one is the more sensitive because it is the only one that will operate at currents between 30 and 100 mA.
There are multiple meanings for the acronym RCD, depending on the location it is used. In the United States, one of the most popular is residual current device. In the United Kingdom, it is short for the Royal College of Defence.
Residual Current Device. Also known as an Earth Leakage Circuit Breaker or a Safety Switch
A Residual Current Device (RCD) in a three-phase system monitors the current flowing through the live conductors and the neutral. If it detects an imbalance, indicating that some current is leaking to the ground (which can occur due to faults), it quickly disconnects the circuit to prevent electric shock or fire hazards. The RCD operates by comparing the current in each phase and the neutral wire, ensuring that the total current entering the system equals the total current leaving. If an imbalance exceeds a preset threshold, it trips the circuit, enhancing safety in three-phase electrical systems.
Use Ohm's law: V = IR (V=voltage, I=current, R=resistance). Example: 3mA flows thru a 1kOhm resistor. V = (0.003 * 1000) = 3V.
