Shop Legrand DX3 MCB 4P 20A B-Curve 10kA Circuit Breaker | 409066 In Iraq Best Prices
Legrand DX3 thermal magnetic circuit-breaker with 4-pole protection, 20A rated current, B-curve release, 10kA breaking capacity, IP20 finger-safe design, and DIN-rail mounting for residential and commercial panel installations.
The Legrand DX3 MCB 409066 is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 4-pole modular device features a 20A rated current with B-curve release characteristic and 10kA breaking capacity at 400V~. The circuit breaker incorporates IP20 finger-safe design protection, ensuring safety in residential and small commercial panel applications. With DIN-rail mounting capability and screwed terminal connections, it accommodates multi-wired conductors from 1.5-25mm² and solid-core conductors from 1.5-35mm². The device operates efficiently across 50-60Hz frequency range with rated voltage of 400V and insulation voltage of 500V.
This MCB is equipped with advanced safety features including energy limitation class 3 according to IEC 60898-1 standard, providing maximum let-through energy limitation. The B-curve tripping threshold operates between 60A and 100A (3 In to 5 In), making it ideal for general-purpose circuit protection. The device can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options. It features a convenient label holder for circuit identification and clear ON/OFF indication on the handle with red and green backgrounds for easy status recognition.
The DX3 circuit breaker is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for system expansion and customization. Built with halogen-free materials and designed through an environmentally conscious process, this product complies with substance-restriction requirements. The device maintains optimal performance across ambient operating temperatures from -25°C to 70°C and storage temperatures from -40°C to 70°C, demonstrating its reliability in diverse environmental conditions.
