Legrand DX3 four-pole 2A circuit breaker with C curve tripping, 25kA breaking capacity, and IP20 finger-safe terminals for reliable electrical circuit protection and control
The Legrand DX3 MCB (Miniature Circuit Breaker) is a four-pole modular thermal-magnetic circuit breaker designed for reliable control, protection, and isolation of electrical circuits in residential and small commercial applications. With a rated current of 2A and C curve tripping characteristic, this breaker provides excellent protection against overloads and short circuits. The device features a breaking capacity of 25kA at 400V AC, ensuring safe operation even during severe fault conditions. Its fully visible breaking mechanism allows users to clearly see the operational status of the circuit at all times.
This circuit breaker is engineered with IP20 finger-safe terminals that protect against solid bodies larger than 12.5mm, making it safe for installation in accessible locations. The DX3 series is compatible with Legrand's comprehensive range of auxiliaries, RCD add-on modules, and accessories, allowing for flexible system configuration. The device can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar from either the top or bottom, providing installation flexibility. With a built-in depth of 44mm and width of 70.8mm, it fits perfectly into standard DIN rail enclosures.
The Legrand DX3 MCB incorporates advanced safety features including on/off indication printed on the handle with red and green backgrounds for easy status identification. It includes a label holder for clear circuit identification and is equipped with two DIN rail clamps allowing independent removal without disturbing the busbar system. The breaker operates reliably across ambient temperatures from -25°C to 70°C and is halogen-free, complying with environmental standards. This product is manufactured with environmental consciousness and meets all substance-restriction requirements, making it an ideal choice for modern electrical installations.
