    Key Products in the Range

    • RCBOs (Residual Current Breakers with Over-Current): These devices combine protection against overcurrent and residual current faults. They are available in single pole and three-pole configurations with 6kA and 10kA breaking capacities. Additionally, Type A RCBOs detect both AC and pulsating DC residual currents, making them ideal for circuits with modern electronic devices.
    • RCDs (Residual Current Devices): RCDs safeguard circuits by detecting earth leakage currents, which helps reduce the risk of electric shocks and fire hazards. They are offered in both single-phase and three-phase configurations, with 30mA sensitivity for maximum safety.
    • MCBs (Miniature Circuit Breakers): These compact devices provide protection against overcurrent and short circuits for individual circuits. With current ratings ranging from 6A to 50A, they offer options for both resistive and inductive loads. Curve B and Curve C variants ensure compatibility with specific load characteristics.
    • Surge Protection Devices (SPDs): SPDs shield electrical systems from voltage spikes caused by lightning or power surges. By protecting sensitive electronics and equipment, they help maintain system reliability.
    • Modular Devices: Modular options include timers, contactors, and isolators, which enhance control and automation within electrical systems.
    Features and Benefits
    • Comprehensive Protection: These devices cover overcurrent, short circuits, earth leakage, and voltage surges. As a result, they ensure complete circuit safety.

    Next Day Delivery

    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 £150 + VAT (double our standard carriage-paid order value of £75 + 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 £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.

    Backorder Delivery Policy

    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.
