Shop Legrand TX3 MCB 3 Pole 50A Circuit Breaker C Curve | 403550 In Iraq Best Prices

Professional 3-pole 50A thermal magnetic circuit-breaker with 6000A breaking capacity, C curve characteristic, IP20 protection, and DIN-rail mounting for reliable electrical system protection

The Legrand TX3 MCB 403550 is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. This robust device features a 6000A breaking capacity at 400V and is equipped with a C curve characteristic, making it ideal for residential and small commercial panel applications. The 3-pole configuration with 50A rated current provides reliable protection for three-phase electrical systems. This circuit-breaker comes with advanced features including IP20 protection rating against solid bodies larger than 12.5mm, DIN-rail mounting capability, and compatibility with both copper cables and prong/fork type supply busbars. The device incorporates energy limitation class 3 according to IEC 60898-1 standard, ensuring maximum protection against fault conditions. The C curve tripping characteristic (between 5In and 10In) provides optimal protection for general wiring installations with moderate inrush currents. The TX3 MCB is designed for easy installation and maintenance with a special DIN rail clamp allowing independent removal even when the fork busbar is still in place. It features a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds. The device can be equipped with Legrand DX3 auxiliaries and accessories, and complies with all substance-restriction requirements with environmentally conscious design principles.
