FuseBox 20A 30mA Type A B Curve 6kA RCBO | RTA062030B

20A Single Module Type A RCBO for FuseBox Consumer Units

The FuseBox RTA062030B is a 20A 30mA Type A B Curve 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 one compact protective device, the RTA062030B protects against overloads, short circuits and residual current / earth leakage faults.

With a 20A rated current, 30mA residual operating current, Type A characteristics, B Curve tripping and 6kA breaking capacity, it provides comprehensive circuit protection while occupying just a single module within the consumer unit.

Combined RCBO Protection

An RCBO combines overcurrent protection and residual current protection within a single device.

The FuseBox RTA062030B therefore provides protection against:

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

Using individual RCBOs also allows protection to be provided on a circuit-by-circuit basis rather than several circuits sharing a single RCD.

Type A Residual Current Protection

The RTA062030B features Type A residual current protection, allowing it to respond to both sinusoidal AC and pulsating DC residual currents.

This makes Type A protection particularly relevant to modern electrical installations, where many appliances and electronic devices can produce residual current waveforms beyond purely sinusoidal AC.

20A B Curve Protection

This model has a rated current of 20A and uses a B Curve tripping characteristic.

The 20A rating makes it suitable for appropriately designed final circuits requiring this level of overcurrent protection.

Protective device selection should always take account of the connected load, cable size, installation method and applicable wiring requirements.

6kA Short-Circuit Breaking Capacity

The RTA062030B has a rated short-circuit breaking capacity of 6000A / 6kA.

This provides short-circuit protection for installations where a 6kA rated protective device is appropriate.

Compact Single Module Design

Occupying only one module, the RTA062030B helps maximise the available space within a FuseBox consumer unit.

The RCBO is designed for mounting onto a standard 35mm DIN rail and incorporates a flying neutral connection for installation within the distribution board.

Individual Circuit Protection

RCBOs provide residual current and overcurrent protection to each individual circuit.

This approach can improve circuit separation because an electrical fault can operate the RCBO protecting the affected circuit rather than relying on a shared RCD protecting multiple outgoing circuits.
