Features 16kA breaking capacity at 230V, B-curve tripping, IP20 fingerproof protection, and modular DIN rail mounting. Ideal for wiring installations requiring reliable overload and short-circuit protection.\n \u003c\/div\u003e\n \n \u003c!-- Long description --\u003e\n \u003cdiv class=\"product-description\"\u003e\n The Legrand DX3 MCB 3 Pole 4A Curve B is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This high-performance device features a breaking capacity of 16kA at 230V and 10kA at 400V, making it ideal for residential and small commercial applications. The B-curve tripping characteristic provides optimal protection with a tripping threshold between 12A and 20A (3-5 times the rated current), ensuring sensitive detection of fault conditions while minimizing nuisance trips during normal operation.\n \n This circuit-breaker offers IP20 \"fingerproof\" protection, preventing accidental contact with live parts and ensuring safe installation in accessible locations. The device features maximum energy limitation (class 3) according to IEC 60898-1 standard, providing superior protection for connected equipment. With its modular design, the MCB can be easily mounted on standard DIN rails using two independent clamps (top and bottom), allowing removal without affecting other circuits in the installation. The product is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality.\n \n The DX3 MCB is constructed with environmentally conscious materials and complies with all substance-restriction requirements. It features a convenient label holder for circuit identification and clear ON\/OFF indication on the handle with red and green backgrounds. The device supports connection via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options. With its robust construction, reliable performance, and comprehensive protection features, this circuit-breaker is an essential component for modern electrical installations.\n \u003c\/div\u003e\n \n
