Thermal magnetic 4-pole circuit breaker with 3A rating, C curve, 6kA breaking capacity, IP20 protection, and DIN rail mounting for reliable overload and short-circuit protection in residential and commercial installations.
The Legrand DX3 MCB 407922 is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 4-pole device features a 3A rated current with C curve characteristic and delivers a breaking capacity of 6000A according to IEC 60898-1 standard for household installations. The circuit breaker offers exceptional protection with high energy limitation class 3 and IP20 finger-safe protection, making it ideal for residential and small commercial applications.
This 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 features a built-in depth of 44mm and is mounted on a DIN rail with two independent clamps allowing removal without disturbing the busbar system. The device includes a convenient label holder for circuit identification and clear ON/OFF indication on the handle with red and green backgrounds for easy status identification.
The MCB DX3 operates at a rated voltage of 400V with rated insulation voltage Ui of 500V and rated impulse withstand voltage Uimp of 4kV. It features a tripping threshold in case of short-circuit between 15A and 30A (C curve between 5 In and 10 In), and can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. The device is halogen-free, environmentally conscious, and complies with all substance-restriction requirements, making it a reliable and sustainable choice for modern electrical installations.
