Shop Legrand DX3 MCB 2 Pole 20A Curve C Circuit Breaker | 410009 In Iraq Best Prices
Legrand DX³ modular 2-pole 20A circuit breaker with 36kA breaking capacity, C curve protection, IP20 finger-safe terminals, and DIN rail mounting for reliable electrical circuit protection.
The Legrand DX³ MCB (Miniature Circuit Breaker) is a modular bipolar 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 36kA at 400V, making it suitable for demanding electrical environments. The circuit breaker features a C curve tripping characteristic, which means it trips at between 5 to 10 times the rated current during short-circuit conditions, providing reliable protection against overcurrents and short circuits.
The DX³ 2-pole 20A breaker is equipped with IP20 finger-safe terminals that protect against solid bodies larger than 12.5mm, ensuring safe operation in compliance with IEC/EN 60529 standards. The device features a red/green mechanical indicator that clearly displays whether the contacts are open or closed, and includes a label holder for convenient circuit identification. The breaker can be supplied by copper cable from either the top or bottom, and is compatible with both solid-core conductors (1.5-50mm²) and multi-wired conductors (1.5-35mm²).
This DX³ circuit breaker is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for flexible system expansion and customization. The device has been designed with environmental consciousness in mind, complying with substance-restriction requirements and featuring halogen-free materials. With its compact 3-module width (53.4mm) and DIN rail mounting capability, it integrates seamlessly into standard electrical panels and distribution boards.
