Shop Legrand MCB DX3 10000A 4 Pole 20A Curve D Circuit Breaker | 409534 In Iraq Best Prices
Four-pole thermal-magnetic circuit breaker with 20A rating, 10kA breaking capacity, D-curve tripping, and IP20 fingerproof protection for reliable electrical system control and overload/short-circuit protection.
The MCB DX3 10000A is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. This four-pole device features a 20A rated current with a D-curve tripping characteristic, offering reliable control for residential and small commercial electrical systems. With a breaking capacity of 10kA at 400V~, this breaker ensures comprehensive protection while maintaining compliance with IEC 60898-1 standards for household installations.
This circuit breaker is equipped with advanced safety features including IP20 fingerproof design that protects against solid bodies larger than 12.5mm. The device can be supplied through multiple connection methods including copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, providing flexible installation options. The D-curve characteristic ensures a tripping threshold between 200A and 280A (10 In to 14 In), making it ideal for applications requiring delayed tripping to accommodate inrush currents.
The MCB DX3 features convenient installation with two DIN rail clamps allowing independent removal without disturbing the main busbar. It includes a label holder for clear circuit identification and status indication with red (OFF) and green (ON) backgrounds on the handle. The device is halogen-free and complies with substance-restriction requirements, demonstrating environmental consciousness in its design and manufacturing process.
