Legrand DX3 4-pole 20A thermal magnetic circuit breaker with C curve, 6kA/10kA breaking capacity, IP20 fingerproof protection, and DIN rail mounting for residential and commercial electrical installations.
The Legrand DX3 MCB 6000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 4-pole device features a 20A rated current with C curve characteristics and operates at 400V~ with a breaking capacity of 6kA/10kA. The circuit breaker is equipped with IP20 "fingerproof" safety protection, preventing accidental contact with live components. It can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar from either the top or bottom side, providing flexible installation options for residential and small commercial applications.
This MCB offers maximum energy limitation with class 3 current limiting capability according to IEC 60898-1 standard. The device features a tripping threshold between 100A and 200A for short-circuit protection, providing reliable protection for circuits up to 20A. It is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for customized protection solutions. The circuit breaker features a convenient label holder for circuit identification and clear on/off indication with red and green backgrounds on the handle for easy status recognition.
The product is halogen-free and designed with environmental consciousness, complying with substance-restriction requirements including RoHS and REACH directives. With a built-in depth of 44mm and mounting width of 4 modular spacings (70.8mm), it fits standard DIN rail installations. The device operates reliably in ambient temperatures from -25°C to 70°C and features independent removal capability with dual DIN rail clamps, making maintenance and replacement straightforward.
