the LT (10K) 63 Ampere 30mA, 2-Pole (DP) RCCB is a circuit protection device manufactured by LT, capable of handling a maximum current of 63 amperes, with a sensitivity of 30 milliamperes for detecting ground faults. It has two poles and can interrupt both the live and neutral conductors.This stands for Residual Current Circuit Breaker. It is a type of circuit protection device designed to quickly disconnect the electrical circuit when it detects a leakage current (residual current) flowing to the ground, thereby preventing electric shock or fire hazards.

10K: Indicates the breaking capacity of the RCCB, which is 10 kiloamperes (10 kA). This value represents the maximum fault current that the RCCB can safely interrupt under specified conditions.

63 Ampere: Denotes the nominal current rating of the RCCB, which is 63 amperes. This rating indicates the maximum continuous current that the RCCB can handle without tripping.

30mA: Indicates the sensitivity of the RCCB, which is 30 milliamperes. This sensitivity allows the RCCB to detect leakage currents as low as 30 milliamperes. Detecting such currents is crucial for quickly disconnecting circuits in the event of a ground fault, reducing the risk of electric shock or fire.

2-Pole (DP): Indicates that the RCCB has two poles or circuits. "2-Pole" means it can simultaneously disconnect both the live and neutral conductors. "DP" stands for "Double Pole."
