Shop Legrand DX3 MCB 4 Pole 40A Curve C Circuit Breaker | 410178 In Iraq Best Prices
Professional 4-pole 40A circuit breaker with 50kA breaking capacity, C-curve protection, IP20 terminals, and DX3 compatibility for reliable electrical circuit control and isolation
The Legrand DX3 MCB 4 Pole 40A 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 advanced circuit breaker delivers exceptional performance with a 50kA breaking capacity at 400V and features a C curve tripping characteristic that provides optimal protection for general-purpose circuits and equipment with moderate inrush currents. The device incorporates IP20 finger-safe terminals ensuring safe installation and operation in compliance with IEC/EN 60529 standards.
Engineered with precision and reliability, this four-pole circuit breaker offers 6 modular spacings for flexible integration into DIN rail-mounted distribution panels. The thermal-magnetic release mechanism ensures rapid response to both overload and short-circuit conditions, with tripping thresholds between 200A and 400A for the C curve characteristic. The breaker features a red/green mechanical indicator that clearly displays the open or closed status of contacts, and includes a convenient label holder for circuit identification. Its halogen-free construction reflects Legrand's commitment to environmental sustainability.
The DX3 circuit breaker is compatible with Legrand's comprehensive range of DX3 auxiliaries, RCD add-on modules, and accessories, providing extensive customization options for complex electrical installations. It supports both copper and aluminum cable connections (with appropriate terminal accessories), operates reliably across 50-60Hz frequency ranges, and maintains performance in ambient temperatures from -25°C to +70°C. With a rated voltage of 400V and insulation voltage of 500V, this circuit breaker meets all international standards including IEC 60947-2 specifications.
