Professional-grade 3-pole 32A thermal magnetic circuit breaker with C-curve protection, 6kA/10kA breaking capacity, IP20 fingerproof design, and DIN rail mounting for residential and small commercial electrical systems.
The Legrand DX3 MCB 3P 32A Curve C is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This high-performance device features a 3-pole configuration rated at 32A with C-curve characteristics at 400V~ three-phase supply. With a breaking capacity of 6kA according to IEC 60898-1 standard for household installations and an upgraded capacity of 10kA according to IEC 60947-2, this circuit breaker provides reliable protection for residential and small commercial electrical systems. The product incorporates energy limitation class 3, offering maximum level of limitation of let-through energy, ensuring enhanced safety and equipment protection.
The MCB DX3 is engineered with advanced protective features including thermal and magnetic trip mechanisms with a C-curve tripping threshold between 160A and 320A (5-10 times rated current), making it ideal for circuits with moderate inrush currents. It features IP20 protection against solid bodies larger than 12.5mm, classified as fingerproof according to IEC/EN 60529 standard. The device can be supplied via copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side), offering flexible installation options. The DIN rail mounting system includes two independent clamps (top and bottom), allowing convenient removal even when the busbar remains in place.
This circuit breaker is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, making it highly versatile for modern electrical installations. The product complies with substance-restriction requirements and has been designed in an environmentally conscious process. It features a convenient label holder for clear circuit identification and On/Off indication on the handle with red and green backgrounds for easy status identification. With halogen-free construction and extensive certifications including VDE, AENOR, and CB agreements, the Legrand DX3 MCB represents a premium solution for electrical protection and distribution.
