This advanced protective device features a 6kA\/10kA breaking capacity and B-curve tripping characteristics, providing reliable 3P protection at 400V~. With IP20 'fingerproof' safety rating, it ensures protection against solid bodies larger than 12.5mm, making it ideal for residential and small commercial applications.\n \n This circuit breaker offers exceptional performance with maximum energy limitation (Class 3 according to IEC 60898-1 standard). It can be supplied by copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). The device features fitted DIN rail clamps for independent removal, and includes a convenient label holder for clear circuit identification. The B-curve tripping provides a short-circuit tripping threshold between 12A and 20A (3In to 5In range).\n \n Compliant with all substance-restriction requirements and designed with environmental consciousness, this MCB integrates seamlessly with Legrand DX3 auxiliaries, RCD add-on modules, and accessories. It features on\/off indication printed on the handle with red and green backgrounds for easy status identification. The device is halogen-free and suitable for connection to aluminum cable with terminal accessory, making it a versatile solution for modern electrical installations.\n \u003c\/div\u003e\n \n \u003c!--
