Shop Legrand RX3 MCB 1 Pole 40A Curve B Circuit Breaker | 419140 In Iraq Best Prices
Professional-grade 40A single pole circuit breaker with 6000A breaking capacity, B-curve protection, and modular DIN rail mounting for residential and commercial installations.
The Legrand RX3 MCB (Miniature Circuit Breaker) is a high-performance single pole circuit breaker rated at 40A with a B-curve release characteristic, designed for residential and small commercial electrical installations. This device features a breaking capacity of 6000A according to IEC 60898-1 standard, providing reliable protection against short-circuits and overloads. The breaker incorporates advanced current limiting technology (Class 3) to minimize let-through energy during fault conditions, ensuring maximum safety for electrical circuits and connected equipment.
The RX3 series is engineered with modular DIN rail mounting design, allowing for flexible installation in distribution panels and switchboards. It can be supplied through copper cables, prong busbars (top or bottom side), or fork busbars (bottom side), providing multiple connection options for various installation configurations. The device is protected against solid bodies larger than 12.5mm with IP20 degree of protection, ensuring fingerproof safety and compliance with IEC/EN 60529 standards.
This circuit breaker is compliant with environmental regulations and has been manufactured using environmentally conscious processes, including RoHS and REACH compliance. The B-curve characteristic with tripping threshold between 3In and 5In (120A-200A for 40A rated current) makes it ideal for circuits with moderate inrush currents typical in residential applications. Professional installation by qualified electricians is recommended to ensure optimal performance and safety.
