FuseBox 25A 30mA Type A B Curve 6kA RCBO | RTA062530B

25A Single Module Type A RCBO for FuseBox Consumer Units

The FuseBox RTA062530B is a 25A 30mA Type A B Curve RCBO designed to provide combined overcurrent and residual current protection for individual circuits within compatible FuseBox consumer units.

By combining the functions of an MCB and RCD in a single compact device, the RTA062530B provides protection against overloads, short circuits and residual current / earth leakage faults.

With its 25A rated current, 30mA residual operating current, Type A characteristics, B Curve tripping and 6kA breaking capacity, this RCBO provides comprehensive individual circuit protection while occupying just one module within the consumer unit.

Combined RCBO Circuit Protection

The FuseBox RTA062530B combines residual current protection and overcurrent protection within a single modular device.

This allows the RCBO to provide protection against three key electrical fault conditions:

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

Using individual RCBOs also provides circuit-by-circuit protection, helping isolate an electrical fault to the affected circuit rather than relying on a shared RCD protecting multiple circuits.

Type A Residual Current Protection

The RTA062530B provides Type A residual current protection, allowing it to respond to both AC and pulsating DC residual currents.

Type A protection is particularly relevant in modern installations where electronic equipment can generate residual currents with characteristics beyond purely sinusoidal AC.

Combined with a 30mA rated residual operating current, the RTA062530B provides additional protection for appropriately designed circuits.

25A B Curve Protection

This model has a rated current of 25A and uses a B Curve tripping characteristic.

Its 25A rating makes it suitable for appropriately designed circuits requiring this level of overcurrent protection.

The correct protective device should always be selected according to the connected load, cable size, installation method and applicable electrical installation requirements.

6kA Short-Circuit Breaking Capacity

The RTA062530B has a rated short-circuit breaking capacity of 6000A / 6kA.

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

Compact Single Module Design

The RTA062530B occupies just one module, helping maximise the available space within a FuseBox consumer unit.

Its compact format makes it particularly useful where several circuits require individual RCBO protection while keeping the overall distribution board installation neat and space-efficient.

The device mounts onto a standard 35mm DIN rail and incorporates a flying neutral connection.

Individual Circuit Protection

Using RCBOs on individual outgoing circuits can provide improved circuit separation compared with arrangements where several circuits share a common RCD.

If an appropriate fault occurs, the RCBO protecting the affected circuit can operate independently, helping minimise disruption to other separately protected circuits within the consumer unit.
