The FuseBox RTA065030B is a single pole and neutral RCBO (1P+N) designed to provide combined protection against overloads, short circuits, and earth leakage faults within a single compact device. Rated at 50 amps with a B curve tripping characteristic, it is suitable for circuits with low to moderate inrush currents, including radial circuits, higher load socket circuits, and dedicated power circuits. The integrated 30mA residual current protection ensures rapid disconnection in the event of an earth fault, improving safety for both users and installations. With a 6kA breaking capacity, the device can safely interrupt fault currents, helping to protect wiring and connected equipment from damage. Its single module width allows efficient use of space within consumer units, making it ideal for modern installations where compact layouts are required. Designed for DIN rail mounting, the RCBO integrates easily into FuseBox distribution boards. Clear switching indicators assist with installation, testing, and maintenance, providing electricians with a practical and reliable circuit protection solution across domestic and light commercial environments.
