Legrand DX3 three-pole 125A C-curve modular circuit breaker with 25kA breaking capacity, IP20 protection, DIN-rail mounting, and fully visible breaking contacts for reliable electrical distribution protection.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a three-pole modular thermal-magnetic circuit breaker designed for residential and small commercial electrical installations. This advanced protective device delivers an impressive 25kA breaking capacity at 400V AC and provides 125A C-curve protection, making it ideal for general purpose applications with moderate inrush currents. The breaker features fully visible breaking contacts, allowing users to clearly confirm the open or closed status through a red/green mechanical indicator, ensuring safe operation and easy circuit identification.
Equipped with IP20 protection rating, this circuit breaker is fingerproof and protected against solid bodies larger than 12.5mm, meeting IEC/EN 60529 standards. The device features DIN-rail mounting for easy installation in distribution panels and accepts a wide range of Legrand DX3 auxiliaries, RCD add-on modules, and accessories for enhanced functionality. With a tripping threshold between 625A and 1250A (C-curve between 5In and 10In), it provides reliable short-circuit protection while minimizing nuisance trips during normal operation.
The DX3 circuit breaker is constructed with environmental consciousness, complying with substance-restriction requirements and incorporating halogen-free materials. It operates reliably in ambient temperatures ranging from -25°C to 70°C and accepts both multi-wired (6-50mm²) and solid-core (6-70mm²) conductor connections via screwed terminals. This modular design with a built-in depth of 47mm and width of 80.1mm ensures compact installation, while the label holder provides clear circuit identification. The product is suitable for copper cable supply from either the top or bottom, offering installation flexibility in modern electrical systems.
