Thermal magnetic 2-pole circuit breaker with 1A B-curve rating, 16kA breaking capacity, IP20 protection, and energy limitation class 3 for residential and commercial wiring protection
The Legrand DX3 MCB 2P 1A Curve B is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a 1A B-curve rating and 16kA breaking capacity at 230V, this 2-pole device provides reliable protection for residential and small commercial applications. The circuit breaker features IP20 finger-safe protection and energy limitation class 3, ensuring maximum safety compliance. It can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options.
This MCB is equipped with two DIN rail clamps allowing independent removal while the prong busbar remains in place. The device includes a label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. Built to comply with IEC 60898-1 standard for household installations, it features a tripping threshold between 3A and 5A for short-circuit protection. The unit is halogen-free and designed with environmental consciousness in mind.
The DX3 series is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, making it highly versatile for different installation requirements. With a rated voltage of 400V and impulse withstand voltage of 4kV, this circuit breaker meets stringent international safety standards. The compact design with 35.4mm width and modular spacing of 2 makes it ideal for space-constrained electrical panels.
