Shop Legrand DX3 MCB 3P 25A 6kA Circuit Breaker B-Curve | 407563 In Iraq Best Prices
Legrand DX3 thermal magnetic circuit-breaker, 3-pole 25A 400V, B-curve, 6kA breaking capacity, IP20 fingerproof, DIN rail mounted, ideal for residential and small commercial electrical protection
The Legrand DX3 MCB 407563 is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 3-pole device delivers a rated current of 25A at 400V with a B-curve characteristic and exceptional 6kA/10kA breaking capacity according to IEC 60898-1 standards for household installations. The tripping threshold in case of short-circuit is precisely set between 75A and 125A (B curve between 3 In and 5 In), ensuring optimal protection for residential and small commercial electrical systems.
Featuring IP20 fingerproof design protection against solid bodies larger than 12.5mm, this circuit-breaker meets IEC/EN 60529 standards and provides maximum energy limitation (energy limitation class 3). The device offers flexible supply options including copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side) connections. With DIN rail mounting and independent removal capability, the MCB allows convenient installation and maintenance without requiring busbar disconnection.
The DX3 MCB incorporates advanced features including a label holder for circuit identification, on/off indication printed on the handle with red and green backgrounds, and compatibility with Legrand DX3 auxiliaries, RCD add-on modules, and accessories. Built with halogen-free materials in an environmentally conscious process, this circuit-breaker complies with substance-restriction requirements and represents modern electrical safety standards. The device operates reliably across ambient temperatures from -25°C to +70°C and supports connectable conductor cross-sections from 1.5mm² to 35mm² for solid-core cables.
