The Navitas N125BR-T 25A Type A RCBO is designed to provide combined protection against overload currents, short circuit currents and earth leakage faults within a single protective device. Suitable for installation within consumer units and distribution boards, it helps simplify circuit protection while reducing the space required when compared to separate MCB and RCD arrangements.

Rated at 25A with a 6kA short circuit breaking capacity, this RCBO is particularly suited to dedicated appliance supplies, workshop circuits, utility installations and specialist power applications where dependable fault protection is essential.

Unlike older Type AC devices, the Type A residual current protection element is designed to detect both alternating residual currents and pulsating DC residual currents generated by modern electronic equipment. This makes it suitable for today's installations where smart controls, electronic appliances, LED lighting and switch mode power supplies are increasingly common.

Every Navitas RCBO is individually tested during manufacture and undergoes a 37 point quality control inspection process before leaving the factory. Combined with independent certification from TÜV Rheinland Germany, this commitment to quality helps ensure dependable operation and consistent performance throughout the life of the installation.

The slim 17mm design allows the device to occupy a single module within the consumer unit, helping electricians maximise available board space while maintaining full RCBO protection on individual circuits.

The 25A RCBO is commonly specified for dedicated circuits supplying fixed loads where additional current capacity is required. Its rating makes it particularly suitable for workshop equipment, larger appliance supplies, utility room installations and specialist power applications where reliable fault protection is essential.

By combining overload, short circuit and residual current protection within a single device, the RCBO helps improve circuit discrimination while reducing the inconvenience associated with faults affecting multiple circuits.

Typical applications include:

• Dedicated appliance supplies

• Workshop and garage circuits

• Utility room installations

• Fixed equipment circuits

• Specialist power applications

• Consumer unit upgrades

• New build electrical installations

Why Navitas RCBOs

Every RCBO sold in the UK carries the same responsibility. It must operate correctly when a fault occurs. The difference is how manufacturers approach the process that gets it there.

At Navitas, quality control is not based on sampling a batch and assuming the remainder will perform the same way. Every RCBO is individually tested before leaving the factory and undergoes a comprehensive 37 point inspection process designed to verify both mechanical and electrical performance.

Our RCBO range is independently certified by TÜV Rheinland Germany to BS EN 61009-1, providing confidence that every device has been assessed against internationally recognised standards. This independent verification sits alongside our own internal testing procedures to help ensure consistency from one device to the next.

Modern electrical installations are changing rapidly. LED lighting, smart technology, electronic controls and switch mode power supplies are now commonplace. That is why Type A protection comes as standard across the Navitas RCBO range, helping installers specify with confidence for today's installations rather than yesterday's.

The result is a protection device designed to provide dependable operation, consistent performance and long term reliability. Because when an RCBO is called upon to operate, there is no second chance.
