Shop Legrand DX3 MCB 4P 50A D Curve 6kA Circuit Breaker | 408152 In Iraq Best Prices
Professional-grade 4-pole, 50A thermal magnetic circuit-breaker with 6kA breaking capacity, D curve characteristic, and IP20 fingerproof protection for residential and commercial electrical installations.
The Legrand DX3 MCB is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 4-pole, 50A rated device features a D curve characteristic with a breaking capacity of 6000A according to IEC 60898-1 standard for household installations. The tripping threshold in case of short-circuit is between 500A and 700A (D curve between 10 In and 14 In), providing reliable protection for electrical systems operating at 400V~. The device offers IP20 "fingerproof" safety protection, preventing contact with solid bodies larger than 12.5mm, making it suitable for residential and small commercial installations.
This 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 when the prong busbar is still in place. The device can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and accessories, and can be connected to aluminum cable with terminal accessory. The label holder allows clear identification of circuits, with ON and OFF indications printed on red and green backgrounds respectively.
The product complies with substance-restriction requirements and has been designed in an environmentally conscious process with a carbon footprint of 3.806 kg CO2 eq. during the manufacturing phase. It features halogen-free construction and meets all relevant safety and environmental standards including RoHS Directive and REACH Declaration requirements.
