Shop Legrand DX3 MCB 1 Pole 40A Curve C Circuit Breaker | 409759 In Iraq Best Prices
Legrand DX3 single-pole modular circuit breaker with 40A C curve, 25kA breaking capacity, IP20 terminals, and visible status indicator for reliable electrical circuit protection and isolation.
The Legrand DX3 MCB is a single-pole modular thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits. This reliable device features a 25kA breaking capacity at 230/400V AC, making it ideal for residential and small commercial panel installations. The 40A C curve characteristic provides optimal protection against overloads and short circuits, with a tripping threshold between 200A and 400A (C curve between 5 In and 10 In). The circuit breaker is equipped with IP20 terminals that are protected against solid bodies larger than 12.5mm, ensuring fingerproof operation according to IEC/EN 60529 standard.
This modular device can be supplied by copper cable from either the top or bottom side and is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. The visible breaking mechanism includes a red/green mechanical indicator that clearly displays the status of contacts (open or closed), along with a label holder for convenient circuit identification. The product features a built-in depth of 47mm and occupies 1.5 modular spacings, making it space-efficient for panel installations.
The DX3 circuit breaker complies with substance-restriction requirements and has been designed with environmental consciousness. It operates reliably across a wide ambient temperature range of -25 to 70°C and supports both solid-core (1.5-50mm²) and multi-wired (1.5-35mm²) conductor connections. Installation should be performed by qualified electricians in compliance with local electrical installation rules to ensure optimal performance and safety.
