Legrand DX³ RCBO 40A Four Pole 30mA (415V AC) - C Curve 6kA 4-Module Safety Switch

Maximum 3-Phase Capacity: Handles up to 40 Amperes of continuous load, providing robust protection for high-wattage 3-phase circuits.

Sensitive 30mA Protection: Provides life-saving earth leakage protection, ensuring even high-power circuits are safe for human environments by tripping at 30mA.

Robust Motor Handling: The C Curve trip profile allows for the high magnetic inrush of heavy 3-phase motors (elevators, large pumps) without nuisance tripping.

Total 4-Pole Isolation: Disconnects all three phases and the neutral simultaneously, ensuring no "floating neutral" or residual voltage remains in the circuit after a fault.

Certified Reliability: Fully compliant with IEC 61009-1, making it the trusted choice for hospitals, luxury high-rises, and industrial plants.
