Shop Legrand RX3 MCB 3 Pole 40A Curve B Circuit Breaker | 419173 In Iraq Best Prices
Professional-grade 3-pole 40A circuit breaker with B-curve characteristic, 6000A breaking capacity, and advanced current limiting technology for reliable protection in residential and commercial installations.
The Legrand RX3 MCB (Miniature Circuit Breaker) is a high-performance 3-pole circuit breaker rated at 40A with a B-curve characteristic, designed for household and small commercial electrical installations. This device offers a breaking capacity of 6000A according to IEC 60898-1 standard, providing reliable protection against overcurrent and short-circuit conditions. The B-curve tripping characteristic ensures rapid response with a tripping threshold between 120A and 200A (3-5 times the rated current), making it ideal for general-purpose applications with moderate inrush currents.
The RX3 circuit breaker features advanced current limiting technology (Class 3) that minimizes let-through energy during fault conditions, protecting downstream equipment from damage. Its compact design with a built-in depth of 44mm allows for flexible installation in standard DIN rail-mounted enclosures. The device can be supplied via copper cables, prong busbars (top or bottom), or fork busbars (bottom side), offering multiple connection options for various installation scenarios. With an IP20 protection rating, the breaker is fingerproof and protected against solid bodies larger than 12.5mm, ensuring safety in residential and commercial environments.
This Legrand product complies with substance-restriction requirements and has been manufactured using environmentally conscious processes. The rated voltage of 400V with an impulse withstand voltage of 4kV ensures compatibility with standard three-phase electrical systems. The RX3 series is engineered to meet stringent international standards and provides long-lasting reliable service in demanding electrical applications.
