Professional 4-pole thermal-magnetic circuit breaker with 80A rating, 36kA breaking capacity, C-curve protection, and IP20 finger-safe terminals for residential and commercial electrical installations
The Legrand DX³ four-pole modular thermal-magnetic circuit breaker (Model 410041) is a professional-grade electrical protection device designed for comprehensive control, protection, and isolation of electrical circuits. With a breaking capacity of 36kA at 400V AC and an 80A C-curve rating, this circuit breaker provides reliable short-circuit protection with a tripping threshold between 400A and 800A. The device features fully visible breaking mechanism and IP20 finger-safe terminals, ensuring safe operation in residential and small commercial installations.
This circuit breaker is equipped with a red/green mechanical indicator that clearly displays the contact status (open or closed) and includes a label holder for convenient circuit identification. The DX³ series is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, providing flexible configuration options for different electrical applications. Built-in depth of 47mm and occupying 6 modular spacings on DIN rails, it integrates seamlessly into standard electrical panels and distribution boards.
The product complies with IEC 60947-2 standards and features environmentally conscious design with halogen-free materials. Operating across a wide temperature range from -25°C to +70°C, the circuit breaker accommodates both solid-core conductors (6-70mm²) and multi-wired conductors (6-50mm²), making it suitable for diverse installation scenarios. The DX³ series represents Legrand's commitment to safety, reliability, and compliance with international electrical standards.
