4-pole thermal-magnetic circuit breaker with 3A rating and B-curve protection. Offers 16kA breaking capacity at 230V and 10kA at 400V. IP20 rated, fingerproof design with DIN rail mounting and comprehensive installation protection.
The Legrand DX3 MCB is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. This 4-pole device features a rated current of 3A with a B-curve release characteristic, offering 16kA breaking capacity at 230V and 10kA at 400V. The breaker provides comprehensive protection for residential and small commercial electrical installations while also enabling control and isolation of the installation. With IP20 protection rating, it safeguards against solid bodies larger than 12.5mm, ensuring fingerproof operation in compliance with IEC/EN 60529 standard.
This circuit breaker is equipped with advanced features including two DIN rail clamps for independent removal when the prong busbar is still in place, and a label holder for clear circuit identification. The device supports multiple supply methods through copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar connections. It incorporates current limiting class 3 for maximum energy limitation according to IEC 60898-1 standard, and can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories.
The MCB operates across a wide ambient temperature range of -25°C to +70°C and features halogen-free construction for environmental compliance. With connectable conductor cross-sections ranging from 1.5-25mm² for multi-wired and 1.5-35mm² for solid-core conductors, this versatile device accommodates diverse installation requirements. The product complies with all substance-restriction requirements and has been designed through an environmentally conscious manufacturing process.
