3 Phase RCBO

A 3 phase RCBO protects all three live wires in a three-phase electrical system. It guards against short circuits, overloads, and earth faults. Unlike standard RCBOs, these devices are true 3-pole or 3-pole plus neutral (3P+N) types. They work well in places where strong, full-phase protection is needed.
Electricians often use them in shops, factories, and large buildings. You can install them in a TPN (three-phase) distribution board. They are a great choice for circuits that power motors, machines, or heavy equipment.
Choose a 3 phase RCBO when your job needs reliable protection across all phases. Most models also come with a 10kA breaking capacity for added safety.

Cut-Off Time and Order Information
To ensure your order qualifies for next day delivery, please place your order by 3:00 PM. This is subject to all items being available on the shelf at the time of your order. For orders where the total value exceeds £200 + VAT (double our standard carriage-paid order value of £100 + VAT), we are happy to split the delivery into two shipments if some items are needed urgently and others are not immediately available. If you have any questions or need further assistance, feel free to reach out to us via WhatsApp for live support. We’re here to help!

In Stock Delivery Policy

Free Next-Day Delivery Over £100 + VAT:
Orders above £100 + VAT qualify for free next-day delivery via DPD for in-stock items. While we strive for timely dispatch, we recommend placing orders early to avoid potential delays. Once dispatched, unexpected issues may arise despite the courier’s efforts.

Orders Below £200 + VAT:
To keep costs manageable, we dispatch your order once all items are ready, including products with longer lead times.

Need items faster? You can pay for an additional delivery service to receive in-stock items sooner. Simply email us with your order details, and we’ll send you a payment link for the extra delivery cost.

Orders Above £200 + VAT:
For larger orders, we can split delivery at no extra cost. In-stock items will be sent immediately, with the remaining items dispatched once available.

Supplier Lead Time & Availability

This item may be sourced from our supplier before dispatch.
The lead time shown is an estimate only and is based on the usual supplier timeframe. It is subject to supplier availability and is not a guaranteed delivery date.
We do not have a live supplier stock feed, so supplier stock can change without notice.
Delivery timers and courier estimates apply once the item is available for dispatch.
If the item is unavailable, we will contact you with the available options, including waiting for stock, choosing an alternative product, cancellation, or a refund for the unavailable item.
This does not affect your statutory rights.

Orders containing only Live Electrical products that are not available from our shelf stock will usually be dispatched directly from Live Electrical. Delivery is generally completed within 2–3 working days, although stock availability, order cut-off times and courier schedules may affect the timing.

For mixed orders containing products from other suppliers, dispatch arrangements may vary, and the order may follow the longest delivery estimate shown.

In the unlikely event that an item becomes unavailable, we will contact you with the available options, which may include waiting for stock, choosing an alternative product or cancelling the unavailable item for a refund.

Delivery info

If this item is not currently on our shelves, we will order it from FuseBox for delivery to our warehouse.

Please note that if your order includes other products with a longer lead time, the complete order may be dispatched once all items are available.
