Professional modular thermal-magnetic circuit breaker with 50kA breaking capacity, C curve protection, and IP20 finger-safe terminals for reliable electrical circuit control and protection
The Legrand DX³ MCB 3 Pole 25A Curve C (Reference 410163) is a professional-grade modular thermal-magnetic circuit breaker designed for reliable control, protection, and isolation of electrical circuits in residential and small commercial applications. This three-pole breaker features a 50kA breaking capacity at 400V, providing superior protection against short circuits and overloads. The C curve tripping characteristic ensures optimal performance with a tripping threshold between 125A and 250A (5 to 10 times the rated current), making it ideal for circuits with moderate inrush currents typical of resistive loads and small induction motors.
Designed with safety and convenience in mind, the DX³ breaker incorporates IP20 finger-safe terminals that comply with IEC/EN 60529 standards, protecting against solid bodies larger than 12.5mm. The device features a red/green mechanical indicator that clearly displays the open or closed status of the contacts, and includes a convenient label holder for circuit identification. Built-in depth of 47mm and a width of 4.5 modular spacings ensure compact installation on standard DIN rails. The breaker operates across a nominal voltage range of 360-440V AC at 50-60Hz frequency.
This Legrand circuit breaker can be supplied from either the top or bottom, offering installation flexibility. It is fully compatible with Legrand DX³ auxiliaries, RCD add-on modules, and various accessories, allowing for system expansion and customization. The product meets all substance-restriction requirements and has been manufactured using environmentally conscious processes. With a halogen-free construction and IK02 degree of impact strength, this breaker provides reliable long-term performance in demanding electrical environments. Professional installation by a qualified electrician is recommended to ensure compliance with local electrical codes and safety standards.
