FuseBox 10A 30mA Type A B Curve 6kA Bi-Directional Mini RCBO | RTAMB10BD

10A Bi-Directional Type A Mini RCBO for FuseBox Consumer Units

The FuseBox RTAMB10BD is a compact 10A 30mA Type A bi-directional mini RCBO designed to provide combined residual current and overcurrent protection for individual circuits within compatible FuseBox consumer units.

Featuring a B Curve tripping characteristic, 6kA short-circuit breaking capacity and 1P+N switched configuration, the RTAMB10BD protects against overloads, short circuits and residual current / earth leakage faults.

Its bi-directional design allows the device to operate where current may flow in either direction, making it particularly relevant to modern electrical installations, including appropriate solar PV and renewable energy applications.

Bi-Directional Circuit Protection

A key feature of the FuseBox RTAMB10BD is its bi-directional operation.

Bi-directional protective devices are designed for installations where electrical current may flow in either direction. This is increasingly important in electrical systems incorporating generation technologies such as solar PV, where electricity can be supplied back through parts of the installation.

The RTAMB10BD therefore provides a modern circuit protection option for appropriately designed installations requiring a 10A bi-directional RCBO.

Combined RCBO Protection

The RTAMB10BD combines the functionality of an MCB and RCD within one device, providing protection against:

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

Providing each outgoing circuit with dedicated RCBO protection can also improve circuit separation compared with arrangements where several circuits share a single RCD.

30mA Type A Residual Current Protection

The RTAMB10BD provides 30mA Type A residual current protection.

Type A RCBOs are designed to detect both sinusoidal AC and pulsating DC residual currents, making them particularly relevant to modern installations incorporating electronic equipment.

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

10A B Curve Protection

This model has a rated current of 10A and uses a B Curve tripping characteristic.

The 10A rating makes it suitable for appropriately designed circuits requiring this level of overcurrent protection, while the B Curve characteristic is commonly used for circuits with relatively low inrush currents.

Correct protective device selection should always take account of the circuit load, cable size, installation method and applicable wiring requirements.

6kA Short-Circuit Breaking Capacity

The FuseBox RTAMB10BD has a rated short-circuit breaking capacity of 6000A / 6kA.

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

Compact 1P+N Switched Design

The RTAMB10BD uses a compact 1P+N switched configuration, providing switching of both the line and neutral.

Despite combining overcurrent protection, residual current protection and switched-neutral functionality, the device occupies just one module within the consumer unit.

Its compact mini RCBO construction helps maximise available wiring and working space, particularly where multiple circuits require individual RCBO protection.

Ideal for Modern & Renewable Energy Installations

Electrical installations are increasingly incorporating technologies that can change the traditional direction of power flow.

The bi-directional design of the RTAMB10BD makes it particularly useful for appropriately designed systems involving renewable generation or other applications where power may flow in either direction through the protective device.

This makes the FuseBox RTAMB range a versatile option when designing modern consumer unit installations.
