FuseBox 6A 30mA Type A B Curve 6kA Bi-Directional Mini RCBO | RTAMB06BD

6A Bi-Directional Type A Mini RCBO for FuseBox Consumer Units

The FuseBox RTAMB06BD is a compact 6A 30mA Type A bi-directional RCBO designed to provide combined overcurrent and residual current protection while allowing current to flow safely in either direction.

Featuring a B Curve tripping characteristic, 6kA short-circuit capacity and 1P+N switched configuration, this mini RCBO protects against overloads, short circuits and earth leakage faults. Its bi-directional design makes it particularly suitable for modern electrical installations incorporating technologies such as solar PV and other applications where current may flow in both directions.

Its compact single-module format also helps maximise working space inside compatible FuseBox consumer units.

Bi-Directional Protection for Modern Installations

One of the key advantages of the RTAMB06BD is its bi-directional design.

Unlike a protective device intended for only one direction of power flow, a bi-directional RCBO can accommodate current flowing in either direction. This makes it particularly relevant to modern installations incorporating solar PV generation and other systems where power flow may not always be exclusively from the supply towards the load.

Combined RCBO Circuit Protection

The RTAMB06BD combines the functions of an MCB and RCD within one compact device, providing protection against:

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

Individual RCBO protection also helps improve circuit separation, allowing the affected circuit to have its own dedicated residual current and overcurrent protection.

Type A 30mA Residual Current Protection

The RTAMB06BD provides Type A residual current protection with a rated residual operating current of 30mA.

Type A devices are designed to respond to AC and pulsating DC residual currents, making them particularly relevant to modern electrical installations incorporating electronic equipment.

6A B Curve Protection

This model has a rated current of 6A and uses a B Curve tripping characteristic.

The B Curve characteristic is specified at 3–5 In, with the 6A rating making the device suitable for appropriately designed lower-current circuits where this level of overcurrent protection is required.

Correct protective device selection should always consider the connected load, cable size, installation method and applicable wiring requirements.

6kA Short-Circuit Capacity

The FuseBox RTAMB06BD has a rated short-circuit breaking capacity of 6000A / 6kA.

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

1P+N Switched Mini Design

The RTAMB06BD features a 1P+N switched configuration, meaning both the line and neutral are switched.

Despite providing combined RCBO protection and switched-neutral functionality, the device occupies just one module, measuring approximately 18mm wide. Its compact construction helps increase available working space inside a FuseBox consumer unit.
