Shop Legrand MCB DX3 6000A 4 Pole 25A Curve C Circuit Breaker | 407930 In Iraq Best Prices
Thermal magnetic 4-pole circuit breaker with 25A rated current, 6000A breaking capacity, C-curve protection, and advanced safety features for reliable electrical installation protection.
The Legrand MCB DX3 is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits in residential and small commercial applications. This 4-pole device operates at 400V with a rated current of 25A and features a C-curve tripping characteristic. It provides exceptional 6000A/10kA breaking capacity according to IEC 60898-1 standard for household installations, with energy limitation class 3 for superior protection. The device is capable of controlling and isolating electrical installations with precision and reliability.
This circuit breaker features advanced safety characteristics including fingerproof protection (IP20) against solid bodies larger than 12.5mm and can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar connections. The tripping threshold in case of short-circuit ranges between 125A and 250A (C curve between 5In and 10In), ensuring optimal protection for sensitive electrical equipment. The MCB can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for customized installation requirements.
Built with environmental consciousness, this product complies with substance-restriction requirements and features halogen-free construction. The device includes a label holder for circuit identification, clear on/off indication on the handle with red and green backgrounds, and is fitted with two DIN rail clamps for independent removal when the prong busbar remains in place. With a rated insulation voltage of 500V and impulse withstand voltage of 4kV, this circuit breaker delivers reliable performance in demanding electrical environments.
