Premium 4-pole modular circuit breaker with 125A D-curve rating and 25kA breaking capacity, featuring IP20 finger-safe terminals and halogen-free construction for reliable electrical circuit protection
The Legrand DX3 MCB 4-pole circuit breaker is a premium modular thermal-magnetic device designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial applications. With a robust 25kA breaking capacity at 400V and D-curve performance rated at 125A, this breaker delivers exceptional reliability and safety. The device features IP20 finger-safe terminals that protect against solid bodies larger than 12.5mm, ensuring maximum safety in any installation environment. Built with halogen-free materials and designed through an environmentally conscious process, this circuit breaker meets all modern sustainability standards.
The DX3 breaker offers superior functionality with its integrated label holder for clear circuit identification and a red/green mechanical indicator that displays the open or closed status of contacts at a glance. The tripping threshold for short-circuit protection ranges between 1250A and 1750A, providing precise D-curve protection between 10In and 14In. The device can be supplied by copper cable from either the top or bottom, offering flexible installation options. With a built-in depth of just 47mm and occupying 6 modular spacings on a DIN rail, this breaker maximizes panel space efficiency while maintaining full functionality.
Compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, the DX3 breaker provides a comprehensive ecosystem for modern electrical installations. The screwed terminal connection type accommodates multi-wired conductors from 6-50mm² and solid-core conductors from 6-70mm², making it suitable for diverse wiring configurations. Operating reliably across ambient temperatures from -25°C to +70°C and rated at 400V with 500V insulation voltage, this circuit breaker is engineered for demanding applications requiring professional-grade protection and performance.
