Premium 1-pole 80A C-curve circuit breaker with 25kA breaking capacity, IP20 terminals, and full Legrand DX3 accessory compatibility for reliable electrical protection.
The Legrand DX3 1-pole 80A curve C circuit breaker is a premium modular thermal-magnetic protection device designed for control, protection, and isolation of electrical circuits. This high-performance breaker features a 25kA breaking capacity at 230/400V AC and incorporates fully visible breaking mechanism with a red/green mechanical indicator to display the contact status. The device is equipped with IP20 finger-safe terminals, providing enhanced safety in residential and small commercial installations. Built with a C-curve characteristic offering tripping thresholds between 400A and 800A (5-10 In), this breaker is ideal for circuits with moderate inrush currents such as general lighting and standard motor loads.
The DX3 series breaker offers exceptional versatility and compatibility with the complete Legrand DX3 accessory range, including RCD add-on modules and various auxiliary equipment. The device features a convenient label holder for clear circuit identification and can be supplied by copper cable from either the top or bottom side. With its compact 1.5 modular spacing design and 47mm built-in depth, this breaker integrates seamlessly into residential and commercial switchboards. The product complies with IEC 60947-2 standards and includes substance-restriction compliance, demonstrating Legrand's commitment to environmental responsibility and safety excellence.
Installation of this circuit breaker should be performed by qualified electricians in compliance with applicable electrical codes and regulations. The device operates reliably across a wide ambient temperature range from -25°C to +70°C and supports conductor cross-sections from 6-70mm² for solid-core cables and 6-50mm² for multi-wired conductors. With its robust construction, advanced protection features, and extensive compatibility options, the Legrand DX3 1P 80A curve C breaker represents an optimal choice for modern electrical distribution systems.
