Premium 2-pole miniature circuit breaker with 10A rating, B curve characteristic, and 6000A breaking capacity for reliable residential electrical protection
The Legrand RX3 MCB (Miniature Circuit Breaker) is a high-performance 2-pole circuit breaker rated at 10A with B curve characteristic, designed for residential and small commercial electrical installations. This device features a breaking capacity of 6000A according to IEC 60898-1 standard, making it ideal for household installations requiring reliable protection against overloads and short circuits. The B curve tripping characteristic provides a tripping threshold between 3In and 5In, offering optimal protection for standard residential circuits.
This circuit breaker is engineered with advanced current-limiting technology (Class 3 energy limitation) that minimizes let-through energy during fault conditions, ensuring superior protection of downstream equipment and reducing arc flash hazards. The device is IP20 rated, providing protection against solid bodies larger than 12.5mm, and can be supplied via copper cable, prong busbar, or fork busbar connections. Built with a compact 35.4mm width fitting standard DIN rail mounting, it integrates seamlessly into residential and small commercial distribution panels.
The RX3 circuit breaker complies with all substance-restriction requirements and has been designed following environmentally conscious manufacturing processes. Its robust construction, rated at 400V nominal voltage with 500V insulation rating and 4kV impulse withstand voltage, ensures long-term reliability and safety in demanding electrical environments. The device operates across 50-60Hz frequencies and features terminal marking indication for easy identification and maintenance.
