Shop Legrand DX3 MCB 2 Pole 3A Curve B 6kA Circuit Breaker | 407504 In Iraq Best Prices
Thermal magnetic 2-pole circuit-breaker with 3A rated current, B-curve characteristic, and 6kA breaking capacity for residential and small commercial wiring protection
The Legrand DX3 MCB 407504 is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a rated current of 3A and B-curve characteristic, this 2-pole device offers a breaking capacity of 6kA according to IEC 60898-1 standard for household installations. The B-curve provides a tripping threshold between 9A and 15A (3 to 5 times the rated current), making it ideal for standard residential and small commercial applications. The device features IP20 protection against solid bodies larger than 12.5mm and belongs to current limiting class 3, providing maximum energy limitation according to IEC 60898-1 standard.
This MCB can be supplied via copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). The device is equipped with two DIN rail clamps, one on the top and one on the bottom, allowing independent removal when the prong busbar is still in place. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality. The circuit-breaker also 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 product complies with substance-restriction requirements and has been designed in an environmentally conscious process. It operates at a rated voltage of 400V with a rated insulation voltage of 500V and impulse withstand voltage of 4kV. The ambient operating temperature range is -25°C to +70°C, with a storage temperature range of -40°C to +70°C. This device is halogen-free and constructed in grey color (RAL 7035), measuring 35.4mm width, 94.8mm height, and 77.8mm depth with a built-in depth of 44mm.
