Shop Legrand DX3 MCB 3P 40A B-curve 6kA Circuit Breaker | 407565 In Iraq Best Prices
Professional-grade thermal-magnetic circuit breaker with 3-pole, 40A capacity and B-curve protection. Features 6kA breaking capacity, IP20 protection, and compatibility with DX3 auxiliaries for comprehensive electrical system protection.
The Legrand DX3 MCB 6000A is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. With a 3-pole configuration, 40A rated current, and B-curve characteristic, this device provides reliable protection for residential and small commercial applications. The circuit breaker features a 6kA breaking capacity according to IEC 60898-1 standard for household installations, with a tripping threshold for short-circuits between 120A and 200A.
This MCB can be supplied by copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). It offers maximum energy limitation with class 3 current limiting capability and is protected against solid bodies larger than 12.5mm with IP20 degree of protection. The device accepts DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality and system integration.
The MCB features two DIN rail clamps for independent removal even when the prong busbar is in place, and includes a label holder for clear circuit identification. With on/off indication printed on the handle in red and green backgrounds, operators can easily identify the device status. This environmentally conscious product complies with substance-restriction requirements and is halogen-free, making it suitable for modern installation standards.
