Legrand DX³ 2-pole modular circuit breaker with 50A C-curve protection, 36kA breaking capacity at 400V, IP20 finger-safe terminals, and DIN-rail mounting for reliable electrical protection
The Legrand DX³ MCB is a modular bipolar thermal-magnetic circuit breaker designed for reliable electrical protection in residential and small commercial applications. This 2-pole breaker delivers exceptional 36kA short-circuit capacity at 400V with C-curve protection rated at 50A, ensuring comprehensive circuit protection against overloads and short circuits. The device features fully visible breaking mechanism with red/green mechanical indicator displaying open/closed status, providing clear visual confirmation of circuit state. With IP20 finger-safe terminals and DIN-rail mounting compatibility, this circuit breaker offers secure installation and safe operation in standard electrical panels.
The DX³ series breaker is engineered with advanced thermal-magnetic technology that provides precise tripping characteristics between 250A and 500A for short-circuit conditions (C curve between 5In and 10In). The device accommodates both copper cable connections from top or bottom orientation, with connectable conductor cross-sections ranging from 1.5-35mm² for multi-wired cables and 1.5-50mm² for solid-core conductors. Its compact 3-modular spacing design (53.4mm width) optimizes panel space while maintaining functionality. The breaker integrates seamlessly with Legrand DX3 auxiliaries, RCD add-on modules, and comprehensive accessories for enhanced protection schemes.
Built with environmental consciousness, this circuit breaker is halogen-free and complies with substance-restriction requirements, making it an eco-friendly choice for modern electrical installations. The device operates reliably across ambient temperatures from -25°C to +70°C, with storage capability from -40°C to +70°C. Its label holder enables clear circuit identification, while the 47mm built-in depth ensures compatibility with standard electrical enclosures. Rated at 400V with 500V insulation voltage and 6kV impulse withstand voltage, the DX³ MCB provides robust protection for contemporary electrical systems.
