Legrand TX3 4-pole 25A C curve thermal magnetic circuit breaker with 6000A breaking capacity at 400V. Provides reliable protection against overloads and short-circuits in three-phase installations with IP20 fingerproof protection and energy limitation class 3.
The Legrand TX3 MCB 4P 25A C curve circuit breaker is a thermal magnetic protective device designed for residential and small commercial electrical installations. With a 6000A breaking capacity at 400V, this four-pole modular circuit breaker provides reliable protection against overloads and short-circuits in three-phase electrical systems. The C curve characteristic ensures a tripping threshold between 125A and 250A (5-10 times the rated current), making it ideal for circuits with moderate inrush currents. This device features a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar is still in place, ensuring safe and convenient maintenance.
The TX3 circuit breaker is built to IEC 60898-1 standards for household installations and offers IP20 protection against solid bodies larger than 12.5mm (fingerproof). It features energy limitation class 3 according to IEC 60898-1, providing maximum protection and minimal let-through energy during fault conditions. The device accepts multiple supply methods including copper cables, prong busbars (top or bottom side), or fork busbars (bottom side), offering flexible installation options. The on/off indication is clearly marked on the handle with red and green backgrounds for easy status identification, and a label holder is provided for circuit identification.
This product complies with RoHS and REACH regulations and has been designed with environmental consciousness in mind. It can be equipped with Legrand DX3 auxiliaries and accessories for enhanced functionality, and can be connected to aluminum cables using Legrand DX3 terminal accessory. The TX3 MCB is a halogen-free, environmentally friendly solution that meets all safety requirements for modern electrical installations.
