Legrand DX3 thermal magnetic MCB providing 13A protection with B-curve tripping, 16kA breaking capacity at 230V, IP20 rated, DIN rail mountable for residential and commercial applications.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 2-pole device features a rated current of 13A with B-curve tripping characteristics, providing reliable protection for residential and small commercial applications. With a breaking capacity of 16kA at 230V and 10kA at 400V, it offers superior performance and safety. The device can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar for flexible installation options.
This MCB is equipped with advanced protection features including IP20 degree of protection and fingerproof design against solid bodies larger than 12.5mm. The B-curve tripping threshold operates between 39A and 65A (3 to 5 times the rated current), making it ideal for standard household circuits. It features energy limitation class 3 according to IEC 60898-1 standard, ensuring maximum protection against short-circuit damage. The device includes a label holder for clear circuit identification and has ON/OFF indication printed on the handle with red and green backgrounds for easy status recognition.
The DX3 MCB is built with DIN rail mounting capability, featuring two independent clamps (top and bottom side) allowing convenient removal even when the busbar is still in place. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality. Compliant with substance-restriction requirements and designed through an environmentally conscious process, this circuit breaker is an essential component for safe electrical installations.
