Thermal magnetic 4-pole circuit breaker with 10kA breaking capacity, 6A rated current, C curve characteristic, IP20 protection, and energy limitation class 3 for reliable household and commercial electrical distribution.
The Legrand TX3 MCB 10000A is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. With a robust 10kA breaking capacity at 400V, this 4-pole 6A device features a C curve release characteristic, providing reliable and efficient protection for household and small commercial electrical distributions. The breaker is IP20 rated, offering protection against solid bodies larger than 12.5mm, and achieves energy limitation class 3 according to IEC 60898-1 standards.
This circuit breaker combines advanced safety features with user-friendly design elements. It can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), offering flexible installation options. The device includes a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar supplying the row remains in place. The integrated label holder enables clear circuit identification, while the ON/OFF indication printed on the handle with red and green backgrounds provides easy status identification.
The TX3 breaker is fully compatible with Legrand DX3 auxiliaries and accessories, and can be connected to aluminium cables using the appropriate Legrand DX3 terminal accessory. Built with halogen-free materials and designed through an environmentally conscious process, this product meets all substance-restriction requirements. Operating at nominal voltages between 240-415V with 50-60Hz frequency, it delivers consistent performance across various electrical installations while maintaining compliance with international safety standards.
