Legrand DX3 4-pole 10A thermal magnetic circuit-breaker with D-curve characteristic, 10kA breaking capacity at 400V, IP20 fingerproof protection, and DIN rail mounting for residential and commercial electrical installations.
The Legrand DX3 MCB 6000A is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. With a 4-pole configuration and 10A rated current, this device features a D-curve characteristic that ensures robust motor protection. The circuit-breaker delivers a 10kA breaking capacity at 400V~, making it ideal for residential and small commercial applications. Its IP20 fingerproof design provides enhanced safety by protecting against solid bodies larger than 12.5mm, complying with IEC/EN 60529 standards.
This MCB can be supplied through multiple connection methods including copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). The device is equipped with two DIN rail clamps positioned on the top and bottom, allowing for independent removal even when the prong busbar is still in place. With a built-in depth of 44mm and width of 70.8mm, it occupies 4 modular spacings on standard DIN rails.
The DX3 MCB complies with IEC 60898-1 standard for household installations and features a tripping threshold for short-circuit between 100A and 140A (D curve between 10 In and 14 In). It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. The device is halogen-free and has been designed with environmental consciousness, featuring a carbon footprint of 3.578 kg CO2 equivalent during the manufacturing phase. A label holder is included for clear circuit identification, with ON/OFF indication printed on the handle using red and green backgrounds.
