Shop Legrand TX3 MCB 2P 10A 10kA Curve C Circuit Breaker | 404203 In Iraq Best Prices
Professional-grade 2-pole thermal magnetic circuit breaker with 10kA breaking capacity, C curve characteristic, and IP20 finger-safe protection for reliable electrical installation protection.
The Legrand TX3 MCB is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 10kA and C curve characteristic, this 2-pole device delivers reliable protection for residential and small commercial applications. The circuit breaker features IP20 finger-safe protection, ensuring safety during installation and maintenance. It can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options for various electrical configurations.
This MCB is equipped with advanced energy limitation technology (Class 3 according to IEC 60898-1 standard), which minimizes the let-through energy during short-circuit events. The device complies with all relevant EU standards and substance-restriction requirements, demonstrating Legrand's commitment to environmental responsibility. The C curve characteristic provides a tripping threshold between 50A and 100A (5In to 10In), making it ideal for circuits with moderate inrush currents typical in residential installations.
The TX3 features a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar remains in place. The on/off indication is clearly marked on the handle with red and green backgrounds for easy status identification. Compatible with Legrand DX3 auxiliaries and accessories, this circuit breaker offers exceptional flexibility for system expansion and customization.
