Shop Legrand RX3 MCB 2 Pole 63A Curve B Circuit Breaker | 419164 In Iraq Best Prices
Professional-grade 2-pole 63A circuit breaker with 6000A breaking capacity, B-curve protection, and Class 3 energy limitation for reliable household and commercial electrical protection.
The Legrand RX3 MCB 2 Pole 63A Curve B Circuit Breaker (Reference 419164) is a high-performance miniature circuit breaker designed for household 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 B-curve characteristic offers a tripping threshold between 189A and 315A (3-5 times the rated current), making it ideal for general purpose circuits with moderate inrush currents.
This two-pole circuit breaker is engineered with advanced current limiting technology (Class 3 energy limitation) that minimizes the let-through energy during fault conditions, ensuring maximum protection for connected equipment and personnel. The device is protected against solid bodies larger than 12.5mm with an IP20 rating according to IEC/EN 60529 standard, offering fingerproof protection. It can be supplied by copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options.
The RX3 series is manufactured with environmentally conscious processes and complies with substance-restriction requirements including RoHS and REACH directives. Built to DIN rail mounting standards with a width of 2 modular spacings, this circuit breaker integrates seamlessly into residential and small commercial distribution panels. Its compact design (35.4mm width, 88.5mm height, 77.8mm depth) ensures space-efficient installation while maintaining robust performance and reliability.
