Four-pole modular thermal-magnetic circuit breaker delivering 80A at 400V with C-curve protection, 10kA/16kA breaking capacity, IP20 fingerproof design, and compatibility with Legrand DX3 accessories for reliable electrical circuit control and protection.
The Legrand DX3 MCB 4 Pole 80A Circuit Breaker is a high-performance modular thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits in residential and small commercial applications. This four-pole device delivers 80A rated current at 400V with a C-curve release characteristic, providing reliable protection against overloads and short circuits. With a breaking capacity of 10kA according to IEC 60898-1 standard and 16kA according to IEC 60947-2, this circuit breaker ensures maximum safety and performance in modern electrical installations.
The DX3 MCB features advanced protection capabilities with a tripping threshold between 400A and 800A for short circuits (C curve between 5In and 10In), making it ideal for circuits with moderate inrush currents. The device is IP20 rated (fingerproof) according to IEC/EN 60529 standard, protecting against solid bodies larger than 12.5mm. It includes a red/green mechanical indicator displaying the open or closed status of contacts, and a label holder for clear circuit identification. The breaker is equipped with a screwed terminal connection type supporting multi-wired conductors from 6-50mm² and solid-core conductors from 6-70mm².
This circuit breaker can be supplied from either the top or bottom, offering flexible installation options. It is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for enhanced functionality and customization. The DX3 MCB complies with substance-restriction requirements and has been designed with environmental consciousness. Operating at ambient temperatures between -25°C and 70°C, with a storage temperature range of -40°C to 70°C, this device is suitable for diverse climatic conditions. The product's carbon footprint during the manufacturing phase is 6.133 kg CO2 equivalent.
