Professional 3-pole thermal magnetic circuit breaker with 10kA breaking capacity, 40A rated current, and B-curve protection for household and commercial electrical installations
The Legrand TX3 MCB 10000A is a professional-grade thermal magnetic circuit breaker designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 10kA at 400V, this 3-pole device delivers reliable protection for household and small commercial electrical circuits. The B-curve tripping characteristic ensures precise and responsive protection, activating between 120A and 200A (3-5 times the rated current) during fault conditions. This device features IP20 protection against solid bodies larger than 12.5mm and complies with IEC 60898-1 standards for household installations.
The TX3 MCB incorporates advanced energy limitation technology (Class 3) to minimize let-through energy during short-circuit events, ensuring maximum safety for connected equipment. The circuit breaker can be supplied through multiple connection methods including copper cables, prong busbars (top or bottom), or fork busbars (bottom side). Its special DIN rail clamp design allows independent removal even when the fork busbar supplying the row remains in place, providing convenient maintenance and replacement capabilities.
With a rated current of 40A and rated voltage of 400V (500V insulation voltage), this device is equipped with a label holder for clear circuit identification and includes ON/OFF indication printed on the handle in red and green backgrounds. The MCB is compatible with Legrand DX3 auxiliaries and accessories, and can be connected to aluminum cables using appropriate Legrand terminal accessories. Constructed with halogen-free materials and designed through environmentally conscious processes, this circuit breaker meets all substance-restriction requirements and delivers dependable performance in demanding electrical environments.
