Shop Legrand DX3 MCB 4 Pole 80A B-Curve 10kA Circuit Breaker | 409089 In Iraq Best Prices
Four-pole modular thermal-magnetic circuit breaker with 80A B-curve protection, 10kA/16kA breaking capacity, IP20 finger-safe terminals, and DIN-rail mounting for residential and small commercial applications.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a four-pole modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits. This advanced device delivers reliable 80A B-curve protection at 400V~ with exceptional 10kA/16kA breaking capacity, making it ideal for residential and small commercial applications. The breaker features IP20 finger-safe terminals and DIN-rail mounting, ensuring safe and secure installation in any electrical panel.
Engineered with precision and durability in mind, this circuit breaker incorporates dual DIN rail clamps positioned at top and bottom, allowing independent removal while the prong busbar remains in place. The device is compatible with copper cables, prong busbars (top or bottom side), fork busbars (bottom side), and Legrand HX3 plug busbars (top side). It includes a convenient label holder for clear circuit identification and On/Off indication printed on the handle with red and green backgrounds for easy status recognition.
The DX3 MCB meets stringent international standards including IEC 60898-1 for household installations and IEC 60947-2 for industrial applications. With a tripping threshold between 240A and 400A (B curve between 3 In and 5 In), this breaker provides optimal protection against short circuits. The device is halogen-free, environmentally conscious, and complies with all substance-restriction requirements. Its robust construction, rated at 500V insulation voltage and 4kV impulse withstand voltage, ensures long-term reliability and safety in demanding electrical environments.
