Shop Legrand TX3 MCB 1P 63A B-Curve 6kA Circuit Breaker | 403363 In Iraq Best Prices
Single-pole thermal-magnetic circuit breaker with 63A rated current, B-curve tripping, 6kA breaking capacity, and IP20 finger-safe protection for residential and commercial electrical installations.
The Legrand TX3 MCB 6000A is a thermal-magnetic circuit breaker designed to protect residential and small commercial wiring installations against overloads and short-circuits. With a breaking capacity of 6kA, it is suitable for 230/400V AC networks and features a B-curve tripping characteristic at 63A rated current. The device offers IP20 finger-safe protection, preventing contact with live parts and solid bodies larger than 12.5mm. This single-pole breaker is equipped with a DIN rail clamp for easy installation and removal, even when fork busbars remain in place. The label holder allows for clear circuit identification with ON/OFF indication printed on the handle in green and red backgrounds respectively.
The TX3 MCB incorporates advanced protection features including current limiting class 3 according to IEC 60898-1 standard, ensuring maximum limitation of let-through energy during short-circuit events. It can be supplied by copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options. The breaker is compatible with Legrand DX3 auxiliaries and accessories, and can connect to aluminum cables using Legrand DX3 terminal accessories. With a compact design measuring 17.8mm width and 44mm built-in depth, it occupies only one modular spacing on standard DIN rails.
This product is manufactured with environmental consciousness and complies with substance-restriction requirements including RoHS and REACH directives. The halogen-free construction and grey RAL 7035 color finish make it suitable for modern electrical installations. Rated at 230V with an impulse withstand voltage of 4kV and operating frequency of 50-60Hz, the TX3 MCB delivers reliable performance across various climatic conditions with storage temperature range from -40°C to +70°C. Professional installation by qualified electricians is recommended to ensure compliance with local electrical codes and safety standards.
