Shop Legrand DX3 Three-Pole 40A Curve D Circuit Breaker | 409837 In Iraq Best Prices
Premium three-pole circuit breaker with 25kA breaking capacity, 40A rating, D-curve protection, and IP20 finger-safe design for reliable electrical distribution and protection.
The Legrand DX³ is a premium three-pole modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial applications. This advanced protection device delivers exceptional 25kA breaking capacity at 400V~, featuring D-curve tripping characteristics that provide optimal protection against short circuits and overloads. With a rated current of 40A and D-curve tripping threshold between 400A and 560A (10-14 times rated current), this circuit breaker offers reliable performance across standard electrical installations.
The DX³ circuit breaker features IP20 finger-safe design, protecting against solid bodies larger than 12.5mm, ensuring safe operation in diverse environments. Built-in depth of 47mm allows for efficient DIN rail mounting with 4.5 modular spacing units. The device includes a red/green mechanical indicator displaying open/closed contact status and a label holder for clear circuit identification. Constructed with halogen-free materials and environmentally conscious design principles, this circuit breaker complies with substance-restriction requirements and RoHS directives.
Supply capabilities include top or bottom copper cable connection with terminal markings, supporting multi-wired conductors from 1.5-35mm² and solid-core conductors from 1.5-50mm². The circuit breaker operates reliably across ambient temperatures from -25°C to 70°C and maintains performance at nominal voltages between 360-440V. Compatible with Legrand DX3 auxiliaries, RCD add-on modules, and accessories, this device provides flexible integration into modern electrical distribution systems. With rated insulation voltage of 500V and impulse withstand voltage of 6kV, it meets international IEC 60947-2 standards for superior electrical protection.
