Shop Legrand DX3 MCB 4 Pole 6A Curve C Circuit Breaker | 409792 In Iraq Best Prices
Professional 4-pole modular circuit breaker with 25kA breaking capacity, 6A C curve protection, IP20 terminals, and DIN rail mounting for reliable electrical circuit protection.
The Legrand DX³ four-pole modular thermal-magnetic circuit breaker is a professional-grade electrical protection device designed for residential and small commercial applications. This MCB delivers exceptional breaking capacity of 25kA at 400V~ with 6A C curve protection, ensuring reliable safeguarding of electrical circuits against overloads and short circuits. The device features fully visible breaking mechanism with IP20 finger-safe terminals, meeting IEC/EN 60529 standards for enhanced safety. Its compact design with DIN rail mounting capability makes it ideal for installation in distribution panels and switchboards.
This circuit breaker is engineered with advanced thermal-magnetic tripping characteristics that provide precise protection with a tripping threshold between 30A and 60A in short-circuit conditions (C curve between 5 In and 10 In). The device can be supplied through multiple connection methods including copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering installation flexibility. With fully visible breaking indication and clear ON/OFF status markings in red and green backgrounds, operators can easily identify circuit status at a glance.
The DX³ series incorporates environmentally conscious design principles and complies with substance-restriction requirements. It features independent removal capability when prong busbar supply is active, dual DIN rail clamps for secure mounting, and compatibility with Legrand DX3 auxiliaries and RCD add-on modules. The label holder allows clear circuit identification, while the halogen-free construction ensures compliance with modern environmental standards. Built-in depth of 44mm ensures space-efficient installation in standard distribution panels.
