FuseBox RTA065030B RCBO Type A 50A 30mA

The FuseBox RTA065030B is a high-capacity RCBO (Residual Current Breaker with Overcurrent Protection) designed to provide reliable protection against overloads, short circuits, and earth leakage faults in residential and light commercial electrical installations. Combining the functions of an MCB and an RCD within a compact single-module device, it maximises available space within consumer units while enhancing circuit safety.

Featuring a B Curve tripping characteristic, the RTA065030B is ideally suited to circuits with low inrush currents, including fixed appliances, heating systems, and dedicated power circuits. Its Type A residual current protection detects both AC and pulsating DC fault currents, making it suitable for modern installations containing electronic equipment, smart devices, and energy-efficient appliances.

With a 50A current rating, 6kA short-circuit breaking capacity, and 30mA residual operating current, this RCBO provides dependable protection against electric shock and fire hazards. Designed specifically for use with FuseBox consumer units, the device features a 1P+N configuration, DIN rail mounting, and a flying neutral lead for fast and efficient installation. Manufactured in accordance with IEC/EN 61009-1 standards, the RTA065030B supports compliance with current wiring regulations and 18th Edition requirements.
