Shop Legrand RX3 MCB 4 Pole 6A Curve C Circuit Breaker | 419738 In Iraq Best Prices
High-performance 4-pole miniature circuit breaker with 6A rating, 4500A breaking capacity, C-curve protection, and IP20 fingerproof design for reliable household and commercial electrical protection.
The Legrand RX3 MCB (Miniature Circuit Breaker) is a high-performance 4-pole circuit breaker designed for household and small commercial electrical installations. With a rated current of 6A and a breaking capacity of 4500A according to IEC 60898-1 standard, this device provides reliable protection against short circuits and overloads. The RX3 features a C-curve tripping characteristic with a short-circuit threshold between 30A and 60A (5 In to 10 In), making it ideal for general-purpose circuits with moderate inrush currents.
This circuit breaker can be supplied with either copper cable or prong busbar connections from the top or bottom, offering flexible installation options. The device is protected against solid bodies larger than 12.5mm with an IP20 rating according to IEC/EN 60529 standard, ensuring fingerproof protection. It achieves maximum energy limitation with class 3 current limiting capability, minimizing let-through energy during fault conditions. The compact DIN rail mounting design with dimensions of 71.2mm width, 88.8mm height, and 77.3mm depth makes it suitable for standard electrical panels and switchboards.
Manufactured by Legrand, a global leader in electrical and digital building infrastructure, the RX3 MCB complies with all substance-restriction requirements and has been designed using environmentally conscious processes. It features a grey RAL 7035 color finish, halogen-free construction, and is rated for AC voltage operation at 50-60 Hz frequency. The device is suitable for nominal voltages between 360-440V and includes concurrent switching of the neutral conductor for enhanced safety.
