Legrand DX3 2-pole 4A thermal magnetic circuit breaker with B-curve, 6000A breaking capacity, IP20 protection, and DIN rail mounting for reliable residential and small commercial electrical protection.
The Legrand DX3 MCB 407505 is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. This 2-pole device features a rated current of 4A with a B-curve characteristic, operating at 230/400V~ with an impressive 6000A breaking capacity. The circuit breaker ensures reliable IP20 protection and is mounted on DIN rails for easy installation and removal. With its advanced energy limitation class 3 technology, this device provides superior short-circuit protection with minimal let-through energy.
This MCB is engineered to meet IEC 60898-1 standards for household installations, offering a tripping threshold between 12A and 20A in case of short-circuits (B curve between 3In and 5In). The device features fingerproof protection against solid bodies larger than 12.5mm, making it safe for residential and small commercial applications. It can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, providing flexible installation options.
The DX3 MCB is compatible with Legrand auxiliaries, RCD add-on modules, and various accessories, allowing for system expansion and customization. Built with halogen-free materials and designed through an environmentally conscious process, this circuit breaker complies with all substance-restriction requirements. The device includes a convenient label holder for circuit identification and clear ON/OFF indication on the handle for easy status monitoring.
