Description

FuseBox Mini RCBO (Bi-directional) RTAM Series is a very compact, highly flexible protection device for contemporary electrical installations. The RCBOs integrate residual current protection and overload protection within a single space-saving module.
Bi-directional capability also renders the RTAM Series perfectly suited for installations where energy flow is in both directions — an excellent fit for solar PV, battery storage, and EV charging installations. Its Type A protection trips reliably for AC and pulsating DC leakage currents, offering a dependable solution for residential and commercial installations.

Rated from 6A–40A, these B-Curve tripping characteristic RCBOs are ideal for general lighting, appliance, and radial circuits. They provide a compact, safe, and reliable solution and are a first choice for new, multi-directional installations.

Key Features

  • Bi-Directional Protection: Enables safe and compliant operation in installations with two-way current flow (e.g., solar PV and battery storage).

  • Type A Residual Current Protection: Sensitive to both AC and pulsating DC leakage currents.

  • B-Curve Tripping Characteristics: Trips between 3–5 times rated current, making it ideal for general-purpose lighting and socket circuits.

  • Compact Single Module Design: Enables space-saving installations within consumer units.

  • Rated Current Options: From 6A to 40A, suitable for a range of load requirements.

  • Earth Fault Protection: All rated at 30mA for personal protection.

  • Short-Circuit Capacity: 6kA rated breaking capacity.

  • Standards Compliance: Conforms with EN 61009-1 and IEC 61009-1.
