Shop Legrand RX3 MCB 2 Pole 40A Curve C Circuit Breaker | 419701 In Iraq Best Prices
Professional-grade 2-pole miniature circuit breaker with 40A rating and 4500A breaking capacity, featuring C-curve protection, IP20 rating, and advanced current limiting technology for residential and commercial applications.
The Legrand RX3 MCB (Miniature Circuit Breaker) is a high-performance 2-pole circuit breaker designed for residential and small commercial electrical installations. With a rated current of 40A and a breaking capacity of 4500A according to IEC 60898-1 standard, this device provides superior protection against electrical overloads and short circuits. The C-curve characteristic (tripping threshold between 200A and 400A, 5-10 times rated current) makes it ideal for circuits with moderate inrush currents typical in residential applications.
This circuit breaker features advanced current limiting technology (Class 3) that minimizes the let-through energy during fault conditions, ensuring maximum protection for downstream equipment. The device is IP20 rated, providing protection against solid bodies larger than 12.5mm, making it suitable for fingerproof installation in standard electrical panels. It can be supplied via copper cable or prong busbar from either the top or bottom, offering flexible installation options.
The RX3 MCB is manufactured with environmental consciousness, complying with all substance-restriction requirements including RoHS and REACH directives. Its compact design (34.6mm width, occupying 2 modular spaces) allows for efficient use of panel space. The device operates at rated voltage of 400V AC with a frequency range of 50-60Hz and includes halogen-free materials for enhanced safety and environmental protection.
