Premium 4-pole 20A miniature circuit breaker with 6000A breaking capacity, C-curve characteristic, and advanced current-limiting protection for residential and commercial applications.
The Legrand RX3 MCB 419258 is a high-performance 4-pole miniature circuit breaker designed for residential and small commercial electrical installations. With a rated current of 20A and a breaking capacity of 6000A according to IEC 60898-1 standard, this device provides exceptional protection against overcurrent and short-circuit faults. The C-curve characteristic offers a tripping threshold between 5In and 10In, making it ideal for circuits with moderate inrush currents typical in residential applications.
This circuit breaker features advanced current-limiting technology (class 3) that minimizes let-through energy during fault conditions, ensuring superior protection for connected equipment and personnel. The device is protected against solid bodies larger than 12.5mm with IP20 rating according to IEC/EN 60529 standard, providing fingerproof protection. It can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), offering flexible installation options for various panel configurations.
The RX3 breaker complies with all substance-restriction requirements and has been designed following environmentally conscious processes. With its compact DIN rail mounting design and grey RAL 7035 finish, this circuit breaker integrates seamlessly into modern electrical distribution panels. The device operates reliably across 50-60 Hz frequency range with rated voltage of 400V AC and impulse withstand voltage of 4kV, ensuring compatibility with standard European electrical systems.
