Legrand DX3 2-pole 6A B-curve thermal magnetic circuit-breaker with 6kA breaking capacity, IP20 finger-safe protection, and DIN rail mounting for residential and small commercial wiring protection.
The Legrand DX3 MCB 2P 6A Curve B is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 6kA according to IEC 60898-1 standard for household installations, this device features B-curve tripping characteristics with a short-circuit tripping threshold between 18A and 30A (3-5 times the rated current). The circuit-breaker is IP20 finger-safe rated, providing protection against solid bodies larger than 12.5mm, making it suitable for standard residential and small commercial applications.
This 2-module DIN rail mounted device offers maximum energy limitation (class 3 according to IEC 60898-1) and can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar. The MCB features a label holder for clear circuit identification, with ON/OFF indication printed on red and green backgrounds respectively. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, and is compatible with aluminum cable connections using terminal accessory n° 4 063 10.
Built to the highest environmental standards, this product is halogen-free and complies with substance-restriction requirements. The device operates reliably across a wide ambient temperature range (-25°C to +70°C) and features dual DIN rail clamps allowing independent removal while the busbar remains in place. With its robust construction and comprehensive protection capabilities, the DX3 MCB 6A is ideal for protecting individual circuits in residential panels and small commercial installations.
