Shop Legrand DX3 MCB 4 Pole 63A Curve C Circuit Breaker | 410040 In Iraq Best Prices
Premium 4-pole modular circuit breaker with 63A capacity, 36kA breaking capacity at 400V, C-curve protection, IP20 finger-safe terminals, and full DX3 auxiliary compatibility for reliable electrical circuit protection.
The Legrand DX3 MCB 4 Pole 63A Curve C is a premium modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial applications. This high-performance device delivers an impressive 36kA breaking capacity at 400V AC, making it suitable for demanding electrical environments. The circuit breaker features a C-curve tripping characteristic with a tripping threshold between 315A and 630A, providing reliable protection against short circuits while minimizing nuisance trips during normal operation.
Built with advanced safety features, this four-pole circuit breaker incorporates IP20 finger-safe terminals that comply with IEC/EN 60529 standards, ensuring protection against solid bodies larger than 12.5mm. The device is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and accessories, allowing for flexible system expansion and customization. With a rated voltage of 400V and insulation voltage of 500V, it handles both single-phase and three-phase systems with neutral conductor switching capability. The mechanical red/green indicator clearly displays the status of contacts, while the integrated label holder enables convenient circuit identification.
The DX3 circuit breaker is engineered with environmentally conscious design principles and complies with substance-restriction requirements. It features a compact depth of 47mm and occupies 6 modular spacings on DIN rail, making it ideal for space-constrained installations. The device operates reliably across a wide ambient temperature range from -25°C to 70°C and accepts both solid-core (1.5-50mm²) and multi-wired (1.5-35mm²) conductors. Whether supplied from top or bottom, this versatile circuit breaker provides professional-grade electrical protection with Legrand's trusted quality and reliability.
