Legrand DX³ four-pole 80A D-curve MCB circuit breaker with 16kA breaking capacity, IP20 finger-safe terminals, and complete DX³ compatibility for residential and commercial electrical protection
The Legrand DX³ MCB 409540 is a four-pole modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial installations. This device delivers exceptional 80A rated current performance with a D-curve release characteristic at 400V~, providing reliable short-circuit protection with a 16kA breaking capacity according to IEC 60947-2 standards and 10kA breaking capacity per IEC 60898-1 for household installations. The circuit breaker features IP20 finger-safe screwed terminals that prevent accidental contact with live parts, making it safe for professional and semi-professional environments.
This advanced circuit breaker incorporates a thermal-magnetic tripping mechanism that offers superior protection against overloads and short circuits with a tripping threshold between 800A and 1120A (D curve between 10In and 14In). The device is compatible with the complete DX³ product range, including RCD add-on modules, earth leakage modules, and various Legrand accessories, enabling flexible system configurations. With a built-in label holder for circuit identification, red/green mechanical status indicator, and support for both copper and aluminum cables (with appropriate terminal accessories), this breaker provides comprehensive electrical protection.
The DX³ MCB meets stringent environmental standards, being halogen-free and designed through an environmentally conscious manufacturing process. It operates reliably across ambient temperatures from -25°C to 70°C, features a pollution degree rating of 2, and includes impact strength rating of IK02. The device measures 70.8mm width, 94.8mm height, and 77.8mm depth, occupying 6 modular spacings on DIN rails. With its carbon footprint of 6.132 kg CO₂eq during the manufacturing phase and compliance with RoHS and REACH regulations, this circuit breaker represents a sustainable choice for modern electrical installations.
