FuseBox 32A 30mA Type A B Curve 6kA RCBO | RTA063230B

32A Single Module Type A RCBO for FuseBox Consumer Units

The FuseBox RTA063230B is a 32A 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 RTA063230B protects against overloads, short circuits and residual current / earth leakage faults.

With a 32A 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 only a single module within the consumer unit.

Combined RCBO Circuit Protection

The FuseBox RTA063230B combines residual current protection and overcurrent protection within a single modular device.

This allows one RCBO to provide protection against three important electrical fault conditions:

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

Providing individual RCBO protection to outgoing circuits also helps improve circuit separation compared with arrangements where multiple circuits share a common RCD.

Type A Residual Current Protection

The RTA063230B provides Type A residual current protection, allowing the device to respond to both AC and pulsating DC residual currents.

This is particularly relevant to modern electrical installations, where electronic equipment and appliances can produce residual current waveforms beyond purely sinusoidal AC.

Combined with a 30mA rated residual operating current, the RTA063230B provides additional residual current protection for appropriately designed circuits.

32A B Curve Protection

The RTA063230B has a 32A rated current and uses a B Curve tripping characteristic.

A 32A protective device is commonly specified for appropriately designed final circuits where the circuit load, conductor size and installation conditions require this rating.

Correct circuit protection must always be selected according to the electrical design, cable characteristics, connected load and applicable wiring requirements.

6kA Short-Circuit Breaking Capacity

The RTA063230B has a rated short-circuit breaking capacity of 6000A / 6kA.

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

Compact Single Module Design

Despite combining residual current and overcurrent protection, the RTA063230B occupies only one module within the consumer unit.

Its compact format helps maximise available space, particularly in installations where numerous circuits require individual RCBO protection.

The device mounts onto a standard 35mm DIN rail and incorporates a 450mm flying neutral connection.

Individual Circuit Protection

Using RCBOs on individual circuits can improve circuit separation and help minimise disruption if a fault develops.

Rather than several circuits relying on a shared RCD, each appropriately protected circuit can have its own RCBO. A fault on one circuit can therefore operate its dedicated protective device without directly relying on the residual current protection serving other circuits.
