Legrand DX³-ID residual current circuit breaker, top entry and bottom exit, screw terminals – 2P 230V~ 40A type AC 30mA – 2 modules (Ref. 4 115 05)

• DX³ two-pole residual current circuit breaker, 230V~ type AC: detects faults with an alternating current component
• Top inlet and bottom outlet via screw terminals
• Rated current 40A – Sensitivity 30mA – 2 modules
• Accepts auxiliary devices, motorized controls and DX³ connection modules
• Compliant with standard NF EN 61008-1

Recommendations / usage restrictions

• The residual current device (RCD) must be protected, upstream or downstream, against overloads by a circuit breaker having at most the same rated current as the RCD.

Product range information

By successfully combining high breaking capacity, high rated current, and a compact design, DX³ modular circuit breakers perfectly meet the requirements for selectivity and space saving, while ensuring optimal protection of people and property as defined by standard NF C 15-100. They prevent the entire installation from being shut down in the event of a fault and increase the breaking capacity of downstream protection. They can be installed in residential, small commercial, and large commercial buildings with breaking capacities from 6 kA to 50 kA. The DX³ STOP ARC circuit breaker is a new Legrand product that limits the risk of fire caused by electrical arc faults. The DX³ range also includes residual current circuit breakers (RCCBs), residual current switches (RCDs), auxiliary devices that enable remote tripping of circuit breakers, and adaptable residual current blocks.
