Shop Legrand DX3 MCB 3 Pole 125A Circuit Breaker C-Curve | 409282 In Iraq Best Prices
Professional 3-pole 125A circuit breaker with C-curve protection, 10kA/16kA breaking capacity, IP20 finger-safe terminals, and advanced mechanical indicator for reliable electrical circuit control and protection.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a three-pole modular thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits in residential and small commercial applications. This professional-grade device offers 125A rated current protection with a C-curve release characteristic, providing reliable short-circuit protection at 400V~ with a breaking capacity of 10kA according to IEC 60898-1 standard for household installations and 16kA according to IEC 60947-2 standard. The breaker features IP20 finger-safe terminals for enhanced safety, preventing accidental contact with live components.
The DX3 circuit breaker is equipped with advanced safety features including a red/green mechanical indicator that clearly displays the open or closed status of the contacts, and a label holder for convenient circuit identification. With a C-curve tripping threshold between 625A and 1250A (5-10 times the rated current), this device provides optimal protection against overloads and short circuits. The unit can be supplied by copper cable from either the top or bottom, offering flexible installation options, and supports connection to aluminum cables with optional terminal accessories.
Built with environmentally conscious design principles and compliance with substance-restriction requirements, the DX3 is halogen-free and features a carbon footprint of 4.966 kg CO2 eq. during manufacturing. The device is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, making it a versatile solution for electrical distribution systems. Installation should be performed by qualified electricians in compliance with local electrical codes and safety regulations.
