Shop Legrand DX3 MCB 1P 40A Curve B 10kA Circuit Breaker | 408876 In Iraq Best Prices
Legrand DX3 single-pole thermal-magnetic circuit breaker with 40A rating, 10kA breaking capacity, B curve protection, and DIN rail mounting for residential and commercial installations.
The Legrand DX3 MCB 10000A 1 pole 40A curve B is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. With a breaking capacity of 10kA and B curve characteristic, this device provides reliable protection for residential and small commercial applications. The circuit breaker features energy limitation class 3 according to IEC 60898-1 standard, ensuring maximum protection against electrical faults. It can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options.
This single-pole MCB is fitted with two DIN rail clamps allowing independent removal even when the prong busbar is still in place. The device is IP20 rated, protecting against solid bodies larger than 12.5mm, making it suitable for various installation environments. It features a label holder for clear circuit identification and has ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. The MCB accepts DX3 auxiliaries, RCD add-on modules, and various accessories, providing comprehensive circuit management capabilities.
The product complies with all substance-restriction requirements and has been designed with environmental consciousness in mind. With a rated voltage of 230V, insulation voltage of 500V, and impulse withstand voltage of 4kV, this circuit breaker meets international safety standards. Its compact design with a built-in depth of 44mm and width of 17.8mm makes it ideal for space-constrained installations. The device operates efficiently across 50-60Hz frequency range and maintains functionality in ambient temperatures from -25°C to 70°C.
