FuseBox 16A 30mA Type A B Curve 6kA Bi-Directional Mini RCBO | RTAMB16BD

16A Bi-Directional Type A Mini RCBO for FuseBox Consumer Units

The FuseBox RTAMB16BD is a compact 16A 30mA Type A bi-directional mini RCBO designed to provide combined residual current and overcurrent protection for individual circuits within compatible FuseBox consumer units.

Combining the functions of an MCB and RCD in a single protective device, the RTAMB16BD provides protection against overloads, short circuits and residual current / earth leakage faults.

Its bi-directional design allows current to flow safely through the device in either direction, making it particularly relevant to modern electrical installations, including appropriately designed solar PV, renewable energy and other installations with bi-directional power flow.

Bi-Directional Protection for Modern Installations

A key feature of the FuseBox RTAMB16BD is its bi-directional operation.

Traditional electrical installations primarily distribute electricity in one direction, from the supply towards the connected loads. Modern installations incorporating technologies such as solar PV generation can involve power flowing in different directions.

A bi-directional RCBO is designed to accommodate this type of power flow, making the RTAMB16BD a versatile option for appropriately designed modern electrical installations.

Combined RCBO Circuit Protection

The RTAMB16BD combines residual current and overcurrent protection within a single compact device.

This allows it to provide protection against:

• Overloads
• Short Circuits
• Residual Current / Earth Leakage Faults

Using individual RCBOs can also improve circuit separation by providing dedicated residual current and overcurrent protection to each appropriately designed outgoing circuit.

30mA Type A Residual Current Protection

The RTAMB16BD provides 30mA Type A residual current protection.

Type A devices are designed to respond to both sinusoidal AC and pulsating DC residual currents, making them particularly relevant to contemporary electrical installations containing electronic equipment.

The 30mA residual operating current provides additional residual current protection for appropriately designed final circuits.

16A B Curve Protection

The RTAMB16BD has a rated current of 16A and features a B Curve tripping characteristic.

Its 16A rating makes the RCBO suitable for appropriately designed circuits requiring this level of overcurrent protection.

The correct protective device should always be selected according to factors including connected load, conductor size, installation method and applicable wiring requirements.

6kA Short-Circuit Breaking Capacity

The FuseBox RTAMB16BD features a 6000A / 6kA short-circuit breaking capacity.

This enables the device to provide short-circuit protection in electrical installations where a 6kA rated protective device is appropriate.

Compact 1P+N Switched Design

The RTAMB16BD features a 1P + N switched configuration, providing switching of both line and neutral.

Despite incorporating residual current protection, overcurrent protection and switched-neutral functionality, its compact mini design occupies just one module within the consumer unit.

This helps maximise available wiring and working space, particularly where several circuits require individual RCBO protection.

Ideal for Solar PV & Renewable Energy Applications

The growth of solar PV and other renewable energy technologies has increased the requirement for electrical equipment capable of accommodating different directions of power flow.

The bi-directional capability of the RTAMB16BD makes it suitable for appropriately designed renewable energy installations where this functionality is required.

Its compact format also makes it a practical option when upgrading or designing FuseBox consumer units for modern electrical systems.
