Bi-Directional 100mA RCBO

Discover our range of 100mA Bi-Directional RCBOs, designed to meet the demands of specialist circuits where standard 30mA protection is not appropriate. These compact, regulation-compliant devices combine overload, short-circuit, and residual current protection into a single unit — offering a higher RCD threshold to reduce nuisance tripping.

100mA Bi-Directional RCBOs – Type A Protection for Specialist Circuits

Each RCBO in this category provides Type A protection with 100mA sensitivity, making them ideal for selected PV and solar installations. The Bi-Directional design allows flexible installation, giving electricians the freedom to fit the device without concern for line/load orientation — a key advantage in modern, distributed systems.

These RCBOs are not suitable for circuits that require 30mA protection under BS 7671. Therefore, only qualified electricians should specify and install them.

Applications:
  • Selected PV and solar installations
  • Specialist circuits with higher leakage currents
  • Systems requiring 100mA protection instead of 30mA

Our 100mA RCBOs come from trusted brands such as Live Electrical, Niglon, and others, offering reliable performance and full compliance with BS EN 61009-1. Whether you’re working on a solar install or a unique commercial application, this range gives you the protection flexibility you need — without compromise.

    Delivery Policy
    Free Next-Day Delivery Over £75 + VAT:
    Orders above £75 + 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 £150 + 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 £150 + 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.
    Dispatch Times
    Items with Lead Times (e.g., 1–3 Working Days):
    This means we need to source the product from our supplier before sending it to you. The estimated dispatch time is displayed on each product page.

    Out of Stock at Supplier:
    If an item is unavailable at the supplier, we will contact you promptly. You’ll have the option to choose an alternative product or request a full refund.
