The operating principle of the 2P 63A/30mA RCD AC Type is based on the residual current transformer. When an unbalanced current (i.e. leakage) occurs in an electrical system, the residual current transformer detects this unbalanced current and generates a magnetic flux proportional to the leakage current. This magnetic flux triggers the RCD's internal release mechanism, causing the RCD to quickly cut off the power supply.

2P: Indicates that this RCD (Residual Current Device) is a bipolar switch, i.e., it can control the on-off of two lines at the same time. This design is usually used where both phase and zero lines need to be cut off at the same time to ensure that the circuit can be completely cut off in the event of a leakage or fault, preventing safety accidents such as electrocution or electrical fires.
63A: Indicates that the RCD is rated at 63 amps. The rated current is the maximum current value that the RCD can carry continuously without causing overheating or damage. In practical applications, the appropriate rated current should be selected according to the load of the electrical system.
30mA: Indicates that the leakage action current of this RCD is 30 mA. The leakage action current is the minimum current value at which the RCD detects leakage current and triggers an action. When the leakage current in the electrical system exceeds this value, the RCD will quickly cut off the power supply to protect personal safety and prevent accidents such as electrical fires.
RCD: Residual Current Device is an electrical safety device used to detect residual current (i.e. leakage current) in an electrical system and cut off the power supply. It is widely used in various low-voltage electrical systems to provide comprehensive protection for electrical equipment and personnel.
AC Type: Indicates that this RCD is suitable for alternating current (AC) systems. Alternating current (AC) is a common way of transmitting electricity and is characterized by periodic changes in the direction of voltage and current compared to direct current (DC). Therefore, when selecting an RCD, the appropriate model should be chosen based on the type of electrical system (AC or DC).
