Thermal-magnetic 2-pole circuit breaker with 2A rating, C-curve characteristic, and 10000A breaking capacity for residential and small commercial wiring protection with IP20 rating and DIN rail mounting.
The Legrand TX3 MCB (Miniature Circuit Breaker) is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. With a 2-pole configuration, 2A rated current, and C-curve tripping characteristic, this device provides reliable protection with a breaking capacity of 10000A according to IEC 60898-1 standard. The breaker features IP20 protection rating, making it fingerproof against solid bodies larger than 12.5mm, and can be supplied via copper cable, prong busbar, or fork busbar connections on DIN rail mounting.
This circuit breaker offers advanced current limiting capabilities with energy limitation class 3 according to IEC 60898-1 standard, ensuring maximum protection for household and small commercial installations. The device operates at rated voltage of 400V with insulation voltage of 500V and impulse withstand voltage of 4kV. It features a special DIN rail clamp on the bottom side allowing independent removal when fork busbar is still in place. The TX3 is equipped with 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 product is halogen-free and complies with substance-restriction requirements, designed in an environmentally conscious process. It can be equipped with Legrand DX3 auxiliaries and accessories, and can be connected to aluminium cable with appropriate terminal accessories. With storage temperature range of -40 to 70°C, frequency range of 50-60Hz, and pollution degree 2 rating, this breaker is suitable for various installation environments and provides professional-grade electrical protection for residential and small commercial applications.
