RCDs 4 Pole

4 pole RCDs provide essential earth fault protection for three-phase systems with a neutral conductor, making them ideal for commercial and industrial installations. These devices monitor all four conductors—three phase and one neutral—and disconnect the supply in the event of a residual current imbalance, helping to prevent electric shock and fire risk. Suitable for use in distribution boards and control panels, 4 pole RCDs are available in various current ratings and sensitivities to suit a range of applications.
