Legrand TX3 thermal magnetic MCB 1 pole 20A with 10000A breaking capacity, IP20 fingerproof protection, and advanced energy limitation for reliable household circuit protection
The Legrand TX3 MCB 20A 1 Pole Circuit Breaker is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 10000A according to IEC 60898-1 standard, this device is ideal for household installations. The circuit breaker features IP20 fingerproof safety protection, making it safe for residential environments. It can be supplied through copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options.
This single-pole MCB is equipped with advanced energy limitation technology (class 3 according to IEC 60898-1 standard), ensuring maximum protection against fault currents. The tripping threshold in case of short-circuit is between 60A and 100A with B curve characteristics (between 3In and 5In). The device includes a special DIN rail clamp on the bottom side, allowing independent removal when the fork busbar is still in place. It features 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 MCB is compatible with Legrand DX3 auxiliaries and accessories, and can be connected to aluminium cable using Legrand DX3 terminal accessory. Complying with substance-restriction requirements, this circuit breaker has been designed in an environmentally conscious process. With dimensions of 17.8mm width, 88mm height, and 77.8mm depth, it occupies minimal space in distribution panels while providing reliable protection for residential and small commercial installations.
