Shop Legrand TX3 MCB 4 Pole 40A Circuit Breaker 10kA | 404158 In Iraq Best Prices
Legrand TX3 4-pole thermal magnetic circuit breaker with 40A rating and 10kA breaking capacity at 400V. Features B curve protection, IP20 rating, energy limitation class 3, and DIN rail mounting for residential and small commercial applications.
The Legrand TX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a 10kA breaking capacity at 400V and B curve characteristics, this 4-pole device provides reliable protection for residential and small commercial applications. The MCB features energy limitation class 3, ensuring maximum protection against electrical faults. It is IP20 rated, offering protection against solid bodies larger than 12.5mm, making it suitable for standard indoor installations.
This circuit breaker can be supplied through copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options. The device is equipped with a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar supplying the row remains in place. The TX3 MCB is compatible with Legrand DX3 auxiliaries and accessories, and can be connected to aluminum cable using Legrand DX3 terminal accessories.
The product features a label holder for clear circuit identification and an intuitive on/off indication printed on the handle with red and green backgrounds for easy status recognition. Operating at 50-60Hz frequency with a rated voltage of 400V and insulation voltage of 500V, this MCB meets international standards including IEC 60898-1 for household installations. The device complies with substance-restriction requirements and has been designed with environmental consciousness in mind.
