Legrand DX3 four-pole modular thermal-magnetic circuit breaker with 32A D-curve rating, 25kA breaking capacity at 400V, IP20 finger-safe terminals, and advanced protection features for residential and commercial applications.
The Legrand DX3 Four-Pole 32A Curve D Circuit Breaker (Model 409849) is a high-performance modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial applications. This device delivers exceptional reliability with a 25kA breaking capacity at 400V, making it suitable for demanding electrical installations. The D-curve characteristic provides optimal protection for circuits with moderate inrush currents, with tripping thresholds between 320A and 448A (10-14 times the rated current). The breaker features IP20 finger-safe terminals that prevent accidental contact with live parts, ensuring enhanced safety in installations. Built with a robust construction and advanced thermal-magnetic trip mechanism, this circuit breaker offers precise and reliable protection against both overload and short-circuit conditions.
This modular circuit breaker is engineered to integrate seamlessly into DX3 distribution systems, accepting a full range of DX3 auxiliary modules, RCD add-on modules, and accessories for enhanced functionality. The device supports connection from either the top or bottom, providing installation flexibility in confined spaces. With a depth of only 47mm and occupying 6 modular spaces, it delivers excellent space efficiency in switchboards and distribution panels. The breaker accommodates both solid-core conductors (1.5-50mm²) and multi-wired conductors (1.5-35mm²), offering maximum versatility for various cable types and sizes. Its halogen-free construction demonstrates Legrand's commitment to environmental responsibility, while the grey RAL 7035 finish provides a professional appearance in any installation.
The DX3 Four-Pole 32A Circuit Breaker incorporates a red/green mechanical indicator for clear status visualization and includes a label holder for convenient circuit identification. Operating across a wide temperature range (-25 to +70°C), this breaker maintains consistent performance in diverse environmental conditions. With an IK02 impact resistance rating and compliance with IEC 60947-2 standards, it delivers dependable protection in both standard and challenging installations. The device is engineered with environmental consciousness, featuring a carbon footprint of 6.742 kg CO2 equivalent during the manufacturing phase, supporting sustainable building practices.
