Shop Legrand DX3 MCB 3-Pole 80A Curve B Circuit Breaker | 409015 In Iraq Best Prices
Professional-grade 80A three-pole circuit breaker with B-curve protection, 10kA/16kA breaking capacity, IP20 rating, and DIN-rail mounting for reliable electrical circuit protection and isolation.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a three-pole modular thermal-magnetic circuit breaker designed for professional control, protection, and isolation of electrical circuits in residential and small commercial installations. This high-performance device features an 80A rated current with B-curve release characteristic, providing reliable protection against overloads and short circuits. Operating at 400V AC with a breaking capacity of 10kA according to IEC 60898-1 standard and 16kA according to IEC 60947-2, this circuit breaker ensures comprehensive circuit protection.
The DX3 circuit breaker is engineered with advanced thermal-magnetic technology that delivers precise tripping thresholds between 240A and 400A (B curve between 3 In and 5 In), making it ideal for general purpose applications. The device features a compact design with IP20 protection rating, making it suitable for standard electrical installations. With DIN-rail mounting capability and dual clamps (top and bottom), this breaker allows independent removal while the prong busbar remains in place, facilitating easy maintenance and circuit management.
This product is equipped with a convenient label holder for clear circuit identification and features ON/OFF indication printed on the handle with red and green backgrounds for easy status recognition. The DX3 can be supplied through various connection methods including copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar. Additionally, it is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and accessories, providing flexibility for system expansion and customization. The device complies with substance-restriction requirements and has been designed following environmentally conscious manufacturing processes.
