Shop Legrand DX3 MCB 4P 4A Curve C Circuit Breaker 6kA | 407923 In Iraq Best Prices
Legrand DX3 4-pole thermal magnetic circuit breaker with 4A rated current, C curve characteristic, and 6kA breaking capacity for residential and small commercial installations. IP20 protected, energy limitation class 3, compatible with DX3 accessories.
The Legrand DX3 MCB 6000A is a thermal magnetic circuit breaker designed to protect and control wiring installations against overloads and short-circuits. This 4-pole device operates at 400V AC with a rated current of 4A and features a C curve tripping characteristic. The circuit breaker provides a breaking capacity of 6kA according to IEC 60898-1 standard for household installations, with short-circuit tripping thresholds between 20A and 40A (C curve between 5 In and 10 In). The device is IP20 rated, offering protection against solid bodies larger than 12.5mm (fingerproof), ensuring safe operation in residential and small commercial environments.
This MCB features advanced energy limitation class 3 according to IEC 60898-1 standard, minimizing let-through energy during fault conditions. The circuit breaker can be supplied by copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). It is equipped with two DIN rail clamps for independent removal while the prong busbar remains in place. The device includes a label holder for clear circuit identification and has On/Off indication printed on the handle with red and green backgrounds for easy status recognition.
The DX3 MCB is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, providing flexible system integration. With a built-in depth of 44mm and width of 70.8mm (4 modular spacings), it fits standard DIN rail installations. The device operates reliably in ambient temperatures from -25°C to +70°C and is halogen-free, complying with substance-restriction requirements and designed with environmental consciousness. Connectable conductor cross-sections range from 1.5mm² to 25mm² for multi-wired cables and 1.5mm² to 35mm² for solid-core conductors.
