Legrand DX³ modular bipolar thermal-magnetic circuit breaker with 50kA breaking capacity, D-curve 40A protection, IP20 finger-safe terminals, and compatibility with DX3 auxiliaries and accessories.
The Legrand DX³ MCB (Miniature Circuit Breaker) is a modular bipolar thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits in residential and small commercial applications. With a robust 50kA breaking capacity at 400V and D-curve 40A protection, this device provides reliable overcurrent and short-circuit protection. The breaker features IP20 finger-safe terminals, ensuring safe operation in various environments. It is supplied with a copper cable connection capability from either the top or bottom, offering flexible installation options. The device is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, making it a versatile solution for modern electrical installations.
This circuit breaker is engineered with advanced thermal-magnetic tripping technology that responds precisely to overload and short-circuit conditions. The D-curve characteristic (tripping threshold between 400A and 560A, or 10-14 times the rated current) makes it ideal for circuits with moderate inrush currents. The built-in red/green mechanical indicator clearly displays the status of the contacts, allowing for easy visual confirmation of the breaker's operational state. The product includes a label holder for convenient circuit identification.
The DX³ series breaker complies with IEC 60947-2 standards and meets substance-restriction requirements while being designed through environmentally conscious processes. Its halogen-free construction and compact 3-module width design (53.4mm) make it suitable for space-constrained panel installations. With an ambient operating temperature range of -25 to 70°C and rated insulation voltage of 500V, this breaker delivers consistent performance across diverse climatic and electrical conditions.
