Shop Legrand DX3 MCB 4 Pole 50A Curve C Circuit Breaker | 409799 In Iraq Best Prices
Professional 4-pole modular thermal-magnetic circuit breaker with 50A rating, 25kA breaking capacity, C-curve protection, and IP20 finger-safe terminals for reliable electrical circuit control and protection.
The Legrand DX3 MCB 4 Pole 50A Curve C is a professional-grade modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial applications. This device features a 25kA breaking capacity at 400V with fully visible breaking mechanism and C-curve tripping characteristics, ensuring reliable protection against overcurrent and short-circuit conditions. The circuit breaker is IP20 finger-safe with screwed terminals, making it suitable for both top and bottom copper cable supply configurations.
Equipped with advanced safety features, this four-pole breaker provides concurrent switching of the neutral conductor and includes a red/green mechanical indicator for clear status visualization. The device is halogen-free and environmentally conscious, complying with RoHS directives and substance-restriction requirements. It can accommodate connectable conductor cross-sections from 1.5 to 50mm² for solid-core cables and 1.5 to 35mm² for multi-wired conductors, offering flexibility in installation scenarios.
The DX3 series breaker is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, making it highly adaptable for complex electrical systems. With its compact 6-module width design (106.8mm) and DIN rail mounting capability, this circuit breaker integrates seamlessly into modern electrical panels. The device operates reliably across a wide temperature range (-25 to 70°C) and maintains consistent performance at frequencies of 50-60 Hz.
