Single-pole 6A miniature circuit breaker with 6000A breaking capacity, C-curve characteristic, and Class 3 current limiting for reliable household electrical protection.
The Legrand RX3 MCB (Miniature Circuit Breaker) is a single-pole circuit breaker designed for residential and small commercial electrical installations. With a rated current of 6A and a breaking capacity of 6000A according to IEC 60898-1 standard, this device provides reliable protection against overloads and short circuits in household installations. The C-curve characteristic ensures tripping between 5 to 10 times the rated current, making it ideal for general-purpose circuits with moderate inrush currents.
This circuit breaker features advanced current limiting technology (Class 3) that significantly reduces let-through energy during fault conditions, providing enhanced protection for connected equipment. The device is protected against solid bodies larger than 12.5mm with IP20 rating according to IEC/EN 60529 standard, ensuring safety and reliability in various installation environments. Its compact design with a width of 17.7mm allows for efficient use of panel space while maintaining excellent electrical performance.
The RX3 breaker can be supplied via copper cable, prong busbar, or fork busbar connections, offering flexible installation options. Built with environmentally conscious design principles and compliance with substance-restriction requirements, this Legrand product represents a commitment to both safety and sustainability. The device operates at 230V nominal voltage with a rated insulation voltage of 500V and impulse withstand voltage of 4kV, suitable for 50-60Hz AC applications.
