FuseBox RTA064530B RCBO SPN 45A 30mA 6kA

The FuseBox RTA064530B is a high-performance 45A RCBO (Residual Current Breaker with Overcurrent Protection) designed to provide combined protection against overloads, short circuits, and earth leakage faults in residential and light commercial electrical installations. By integrating MCB and RCD functionality into a compact single-module device, it maximises available space within consumer units while enhancing overall circuit safety.

Featuring a B Curve tripping characteristic, the RTA064530B is ideal for circuits with low to moderate inrush currents, including fixed appliances, heating circuits, and general-purpose power supplies. Its Type A residual current protection detects both AC and pulsating DC fault currents, making it suitable for modern installations with electronic equipment and energy-efficient appliances.

With a 6kA short-circuit breaking capacity and 30mA residual operating current, this RCBO provides reliable protection against electric shock and fire hazards. Designed for use with FuseBox consumer units, it features a 1P+N configuration, DIN rail mounting, and an integrated flying neutral lead for quick and efficient installation. Manufactured in accordance with IEC/EN 61009-1 standards, the RTA064530B supports compliance with current wiring regulations and 18th Edition requirements.
