Shop Legrand TX3 MCB 4 Pole 10A Circuit Breaker 10kA | 404152 In Iraq Best Prices
Legrand TX3 4-pole thermal magnetic circuit breaker with 10A rating and 10kA breaking capacity, featuring B-curve protection, IP20 rating, and flexible busbar/cable supply options for residential and commercial installations.
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 robust 10kA breaking capacity at 400V. This 4-pole device features a B-curve characteristic with 10A rated current, providing precise protection for residential and small commercial electrical systems. The TX3 series offers flexible supply options through copper cables, prong busbars (top or bottom side), or fork busbars (bottom side), making it suitable for various installation configurations.
This circuit breaker is engineered with advanced protection features including current limiting class 3 according to IEC 60898-1 standard, ensuring maximum limitation of let-through energy. The device is fingerproof with IP20 protection rating against solid bodies larger than 12.5mm, complying with IEC/EN 60529 standards. The B-curve design provides a tripping threshold between 30A and 50A in case of short-circuit, offering reliable protection while minimizing nuisance trips.
The TX3 MCB features a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar is still in place. It includes an integrated label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. The product is halogen-free and designed with environmental consciousness, complying with RoHS and REACH regulations. It can be equipped with Legrand DX3 auxiliaries and accessories, and supports connection to aluminum cables with appropriate terminal accessories.
