Shop Legrand DX3 MCB 1 Pole 125A Curve C Circuit Breaker | 409764 In Iraq Best Prices
Single-pole modular thermal-magnetic circuit breaker with 125A C-curve protection, 25kA breaking capacity, IP20 finger-safe terminals, and full DX3 range compatibility for residential and commercial electrical installations.
The Legrand DX3 MCB is a single-pole modular thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits in residential and small commercial applications. This high-performance device offers a breaking capacity of 25kA at 230V with C-curve protection characteristics between 5In and 10In (625A-1250A tripping threshold). The breaker features IP20 finger-safe terminals and is compatible with the complete DX3 range of auxiliaries, RCD add-on modules, and accessories, making it an ideal choice for modern electrical installations.
With a rated current of 125A and rated voltage of 230V, this circuit breaker provides reliable protection against overloads and short circuits. The device includes a red/green mechanical indicator displaying the open or closed status of contacts, along with a convenient label holder for clear circuit identification. The 1.5 modular spacing width allows for efficient panel organization while maintaining compatibility with standard DX3 mounting systems. Built-in depth of 47mm ensures proper installation in flush-mounted applications.
The DX3 MCB complies with IEC 60947-2 standards and includes substance-restriction requirements, demonstrating Legrand's commitment to environmental responsibility. It can be supplied by copper cable from either the top or bottom side and features connectable conductor cross sections ranging from 6-70mm² for solid-core cables and 6-50mm² for multi-wired cables. The device operates reliably across a frequency range of 50-60Hz and maintains performance within an ambient temperature range of -25 to 70°C.
