FuseBox 32A 30mA Type A B Curve 6kA Bi-Directional Mini RCBO | RTAMB32BD

32A Bi-Directional Type A Mini RCBO for FuseBox Consumer Units

The FuseBox RTAMB32BD is a compact 32A 30mA Type A bi-directional mini 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 within a single protective device, the RTAMB32BD protects against overloads, short circuits and residual current / earth leakage faults.

Its bi-directional operation allows the device to be used in appropriately designed installations where current may flow in either direction, making it particularly relevant to modern electrical systems incorporating solar PV, renewable generation and other bi-directional power applications.

Bi-Directional Protection for Modern Electrical Systems

The key advantage of the FuseBox RTAMB32BD is its bi-directional capability.

In a traditional electrical circuit, power typically flows from the supply towards the connected load. Modern electrical installations can also incorporate local generation, meaning power may need to flow in either direction through parts of the installation.

The RTAMB32BD is designed to accommodate bi-directional power flow, making it a useful circuit protection solution for appropriately designed modern electrical and renewable energy systems.

Ideal for Solar PV Applications

Solar photovoltaic installations are a key example of where bi-directional circuit protection may be required.

Because a solar PV system generates electricity locally, power flow within the electrical installation can differ from that of a conventional load-only circuit.

The bi-directional design of the RTAMB32BD makes it particularly relevant to appropriately designed solar PV and renewable generation installations requiring a 32A Type A RCBO.

Combined RCBO Circuit Protection

The RTAMB32BD combines residual current protection and overcurrent protection within one compact device.

It provides protection against:

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

Using individual RCBOs also provides dedicated protection to each outgoing circuit rather than relying on a single shared RCD to provide residual current protection to several circuits.

30mA Type A Residual Current Protection

The RTAMB32BD provides 30mA Type A residual current protection.

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

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

32A B Curve Protection

With a rated current of 32A, the RTAMB32BD features a B Curve tripping characteristic.

Its 32A rating makes it suitable for appropriately designed circuits requiring this level of overcurrent protection.

Correct RCBO selection should always take account of factors including the connected load, conductor size, installation method, prospective fault current and applicable wiring requirements.

6kA Short-Circuit Breaking Capacity

The FuseBox RTAMB32BD has a rated short-circuit breaking capacity of 6000A / 6kA.

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

Compact 1P+N Switched Design

The RTAMB32BD features a 1P + N switched configuration, providing switching of both line and neutral.

Despite incorporating overcurrent protection, residual current protection and switched-neutral functionality, its compact design occupies just one module.

The mini RCBO format helps maximise available wiring and working space within the consumer unit, particularly where multiple outgoing circuits require individual RCBO protection.
