The Legrand MCB TX3 10000A is a high-performance thermal magnetic circuit-breaker designed to protect and control wiring installations against overloads and short-circuits. With a breaking capacity of 10kA at 400V, this 3-pole device features a B-curve tripping characteristic at 20A rated current, providing reliable protection for residential and small commercial applications. The circuit-breaker is equipped with IP20 safety rating, protecting against solid bodies larger than 12.5mm, and features DIN rail mounting for easy installation and removal.
This advanced circuit-breaker incorporates current-limiting class 3 technology according to IEC 60898-1 standard, offering maximum limitation of let-through energy. The device can be supplied by copper cable, prong busbar, or fork busbar connections, providing flexible installation options. The TX3 is compatible with Legrand DX3 auxiliaries and accessories, and includes a special DIN rail clamp that allows independent removal even when the fork busbar is still in place. The product features a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds.
Designed with environmental consciousness, the MCB TX3 complies with substance-restriction requirements and is halogen-free. It operates at rated voltage of 400V with insulation voltage of 500V and impulse withstand voltage of 4kV. The device is suitable for flush-mounted installation and features a compact design with dimensions of 53.1mm width, 88mm height, and 77.8mm depth. Storage temperature range is -40°C to 70°C, and it operates at frequency of 50-60 Hz.
