Legrand DX³ RCBO 63A 100mA 4-Pole (AC Type) - 415V 6kA Three-Phase Master Safety Switch - Legrand Ref: 411374

High-Capacity Master Protection: The 63A rating allows this unit to serve as the primary safety gate for entire three-phase sub-boards or heavy industrial plant machinery.

Superior DX³ Engineering: Part of Legrand’s flagship professional series, offering a 6kA breaking capacity designed to handle significant fault levels in commercial environments.

Advanced Fire Safety (100mA): Specifically engineered to detect earth leakage at levels that prevent electrical fires, providing a critical layer of insurance for high-value facilities.

Total Circuit Isolation: The 4-pole design ensures that in the event of a fault, all three phases and the neutral are disconnected simultaneously, guaranteeing safety for downstream maintenance.

Dual-Function Space Efficiency: Combines the work of a 4-pole MCB and a 4-pole RCCB into one 4-module (70mm) unit, saving 50% of the space compared to traditional two-device setups.
