Shop Legrand TX3 MCB 3P 10A Curve B 10kA Circuit Breaker | 404124 In Iraq Best Prices
Thermal magnetic 3P 10A circuit breaker with 10kA breaking capacity, B-curve protection, DIN rail mounting, and IP20 rating for reliable electrical installation protection.
The Legrand MCB TX3 10000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a 10kA breaking capacity at 400V~, this 3-pole 10A B-curve device offers reliable protection for residential and small commercial applications. The circuit breaker features DIN rail mounting for easy installation and removal, making it ideal for controlling and isolating circuits in electrical distribution panels. Its advanced design includes energy limitation class 3 according to IEC 60898-1 standards, ensuring maximum protection against electrical faults.
This MCB is built 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 device is IP20 rated, protected against solid bodies larger than 12.5mm (fingerproof), and complies with all relevant safety standards. It can be supplied by copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options. The product includes a label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status identification.
The TX3 circuit breaker is fully compatible with Legrand DX3 auxiliaries and accessories, and can be connected to aluminium cables using Legrand DX3 terminal accessory. This environmentally conscious product meets substance-restriction requirements and is halogen-free, making it suitable for modern sustainable electrical installations. With its robust construction, reliable performance, and comprehensive protection features, this circuit breaker is an essential component for any electrical distribution system.
