It combines thermal tripping against sustained overloads and instantaneous magnetic tripping against short circuits, ensuring service continuity and the safety of wiring and receivers. Its \u003cstrong\u003eCurve C\u003c\/strong\u003e characteristic offers tolerance to moderate inrush currents typical of motors, compressors, pumps, and power electronics, preventing unwanted tripping without compromising fast response to real faults. With robust construction, self-extinguishing materials, and a lever with clear ON\/OFF indication, it integrates neatly into professional panels for residential, tertiary, light industrial, or solar self-consumption applications on the AC side.\u003c\/p\u003e\n\n\u003ch3\u003eMain Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4 poles (L1-L2-L3-N), 40 A\u003c\/strong\u003e: simultaneous disconnection of the three phases and the neutral.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e400 V~ 50\/60 Hz\u003c\/strong\u003e: suitable for standard low voltage three-phase distribution.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurve C\u003c\/strong\u003e: immunity to moderate inrush currents (motors\/electronics) and effective response to short circuits.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBreaking capacity up to 6 kA\u003c\/strong\u003e under standard conditions, an adequate level for most LV panels.\u003c\/li\u003e\n  \u003cli\u003eFormat \u003cstrong\u003eDIN 35 mm\u003c\/strong\u003e with quick mounting, status indicator, and reliable operation.\u003c\/li\u003e\n  \u003cli\u003eHigh-quality screw terminals for rigid or flexible cable and compatibility with busbar combs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAdvantages or Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eComplete circuit protection: limits fault energy and prevents damage to conductors and equipment.\u003c\/li\u003e\n  \u003cli\u003eGreater service continuity thanks to Curve C, which reduces nuisance tripping due to inrush currents.\u003c\/li\u003e\n  \u003cli\u003eQuick and tidy installation on DIN rail, with accessibility for maintenance and verification.\u003c\/li\u003e\n  \u003cli\u003eCompatibility with residual current devices and SPD to configure selective and effective protection chains.\u003c\/li\u003e\n  \u003cli\u003eHigh durability due to its modular design, precise mechanism, and self-extinguishing materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePurpose or Applications\u003c\/h3\u003e\n\u003cp\u003eDesigned for high-demand three-phase branch circuits: subpanels, power lines, pumps and treatment plants, HVAC, light machinery, AC distribution of three-phase inverters, and general services in SMEs and commercial premises.
