BG CUR6330A 63A 30mA Type A Bidirectional Double Pole RCD – 2 Module

The BG CUR6330A-02 63A bidirectional Type A RCD provides reliable 30mA earth-leakage protection for modern domestic, commercial and renewable-energy electrical installations. It continually monitors the current flowing through the live and neutral conductors and rapidly disconnects the supply when a potentially dangerous residual-current imbalance is detected.

Its bidirectional design allows the device to operate where electrical current may flow in either direction. This makes the CUR6330A-02 suitable for compatible solar PV systems, EV charging installations and other electrical systems that may import, generate or export power.

The double-pole switching mechanism disconnects both the live and neutral conductors when the RCD trips. Rated at 63A with a 30mA residual-current sensitivity, the electro-mechanical device has an official trip speed of less than 0.1 seconds, helping provide responsive protection against earth-leakage faults and the risk of electric shock.
