Thermal magnetic 4-pole circuit-breaker with 6000A breaking capacity, B curve, and IP20 protection. Ideal for residential and small commercial electrical installations with reliable overload and short-circuit protection.
The Legrand DX3 MCB 6000A 4 Pole 1A Curve B is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 6000A and B curve characteristics, this device provides reliable protection and control for residential and small commercial electrical installations. The circuit-breaker features a tripping threshold between 3A and 5A (B curve between 3In and 5In) and complies with IEC 60898-1 standard for household installations.
This 4-pole modular circuit-breaker can be supplied via copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). It is protected against solid bodies larger than 12.5mm with IP20 rating according to IEC/EN 60529 standard. The device achieves maximum energy limitation with class 3 energy limitation according to IEC 60898-1 standard, ensuring superior protection for your electrical circuits.
The MCB DX3 is equipped with two DIN rail clamps allowing independent removal while the busbar remains in place. It features a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds. The device can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, making it highly adaptable to different installation requirements. Manufactured with halogen-free materials and designed with environmental consciousness, this circuit-breaker meets all substance-restriction requirements.
