Shop Legrand TX3 MCB 4 Pole 40A Circuit Breaker 10kA | 404260 In Iraq Best Prices
Legrand TX3 thermal magnetic circuit-breaker with 4-pole 40A C-curve protection, 10kA breaking capacity, IP20 fingerproof design, and DIN rail mounting for reliable electrical system protection.
The Legrand TX3 MCB is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a 4-pole configuration and 40A rated current, this device offers reliable control and isolation for residential and small commercial electrical systems. The TX3 features a 10kA breaking capacity at 400V, ensuring superior protection against electrical faults. Its C curve tripping characteristic provides optimal protection between 200A and 400A short-circuit thresholds, making it ideal for standard installations requiring consistent overload and short-circuit protection.
This circuit-breaker is engineered with an IP20 fingerproof design that protects against solid bodies larger than 12.5mm, ensuring safe operation in various environments. The device can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), offering flexible installation options. With a built-in depth of 44mm and DIN rail mounting capability, the TX3 integrates seamlessly into existing switchboards and distribution panels. The maximum energy limitation class 3 according to IEC 60898-1 standard ensures minimal let-through energy during fault conditions.
The TX3 MCB is compatible with Legrand DX3 auxiliaries and accessories, allowing for expanded functionality and customization. The device features a convenient label holder for circuit identification and on/off indication printed on the handle with red and green backgrounds for easy status visibility. With its halogen-free construction and environmentally conscious design, the TX3 complies with substance-restriction requirements. This product meets all relevant international standards including IEC 60898-1 for household installations and IEC/EN 60529 for protection degree classification.
