Shop Legrand DX3 MCB 1 Pole 63A Curve C Circuit Breaker | 407676 In Iraq Best Prices
Single-pole thermal magnetic circuit breaker with 63A rated current, C curve characteristic, and 6kA breaking capacity for reliable protection of household electrical installations on DIN rail systems.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a rated current of 63A and C curve characteristic, this single-pole device provides reliable control and isolation on DIN rail mounting systems. The device features a 6kA breaking capacity according to IEC 60898-1 standard for household installations, with a tripping threshold for short-circuits between 315A and 630A (C curve between 5 In and 10 In). The MCB is protected against solid bodies larger than 12.5mm with IP20 finger-safe design, ensuring safe operation in various electrical installations.
This circuit breaker can be supplied by copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side), offering flexible installation options. The device achieves maximum energy limitation with class 3 according to IEC 60898-1 standard and can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. It features two DIN rail clamps (top and bottom) allowing independent removal when the prong busbar is still in place, and includes a label holder for clear circuit identification with ON/OFF indication printed on the handle for easy status identification.
The product complies with substance-restriction requirements and has been designed in an environmentally conscious process. With halogen-free construction and a carbon footprint of 1.018 kg CO2 eq during the manufacturing phase, this MCB represents a commitment to both safety and environmental responsibility in electrical installations.
