Shop Legrand DX3 MCB 2 Pole 16A Circuit Breaker Type B | 408942 In Iraq Best Prices
Legrand DX3 2-pole 16A thermal magnetic circuit-breaker with 10kA breaking capacity, B-curve protection, IP20 safety rating, and environmentally conscious design for residential and commercial electrical installations.
The Legrand DX3 MCB is a thermal magnetic circuit-breaker designed to protect residential and small commercial wiring installations against overloads and short-circuits. With a rated breaking capacity of 10,000A at 230V and 16,000A at 400V, this 2-pole device features a B-curve tripping characteristic that provides reliable protection for circuits rated at 16A. The circuit-breaker is suitable for both protection and isolation of electrical installations, making it an essential component in modern electrical distribution systems.
This device incorporates advanced safety features including IP20 protection against solid bodies larger than 12.5mm (fingerproof), energy limitation class 3 according to IEC 60898-1 standard, and compatibility with Legrand DX3 auxiliaries and RCD add-on modules. The MCB can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options. Built with two DIN rail clamps for independent removal and featuring a label holder for clear circuit identification, this device combines functionality with user-friendly design.
The Legrand DX3 MCB operates reliably across ambient temperatures from -25°C to +70°C and complies with substance-restriction requirements while being designed through an environmentally conscious process. With halogen-free materials and a carbon footprint of 1.827 kg CO2 equivalent during the manufacturing phase, this circuit-breaker represents a commitment to both safety and environmental sustainability in electrical installations.
