Shop Legrand DX3 MCB 4 Pole 63A Curve D Circuit Breaker | 409852 In Iraq Best Prices
Premium four-pole modular circuit breaker with 63A D-curve rating, 25kA breaking capacity, IP20 finger-safe terminals, and full DX3 compatibility for reliable electrical circuit protection.
The Legrand DX³ MCB is a four-pole modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial applications. This robust device delivers a 25kA breaking capacity at 400V~ and features a D-curve tripping characteristic with a rated current of 63A, making it ideal for circuits requiring moderate overload protection. The breaker incorporates IP20 finger-safe terminals that protect against solid bodies larger than 12.5mm, ensuring enhanced safety in installation environments.
This circuit breaker is engineered with advanced thermal-magnetic technology that provides reliable short-circuit protection with a tripping threshold between 630A and 882A (D curve between 10 In and 14 In). The DX³ breaker is fully compatible with Legrand DX3 auxiliary modules, RCD add-on modules, and comprehensive accessories, allowing for flexible system expansion and customization. It features a red/green mechanical indicator that clearly displays the open or closed status of contacts, and includes a convenient label holder for circuit identification.
The device is constructed with environmentally conscious design principles and complies with substance-restriction requirements. It can be supplied by copper cable from either the top or bottom, and features screwed terminals suitable for both solid-core (1.5-50 mm²) and multi-wired (1.5-35 mm²) conductors. With a built-in depth of 47mm and width of 6 modular spacings, it integrates seamlessly into DIN rail-mounted distribution panels. The breaker operates reliably across a wide ambient temperature range of -25 to 70°C and includes halogen-free construction for enhanced environmental performance.
