Combining a robust 100A main isolator switch with built-in surge protection device (SPD) technology, it helps safeguard electrical systems and connected equipment from damaging voltage spikes and transient surges. Engineered for professional installations, the WEC440SP provides a dependable all-in-one solution where effective isolation and surge protection are essential. Ideal for electricians requiring a high-quality 100A metered supply isolator with integrated SPD protection, it offers reliable performance, enhanced safety and long-term peace of mind across a wide range of applications. Review: A decent quality solution for SPD and switch close to the meter. - A nicely packaged solution offering a type 2 SPD that can be mounted where a normal isolator would be, so well within the 50cm of the origin of the installation from the regs. Nice that it also gives the option to output two sets of tails, saving on separate blocks. Had no issues fitting it. Torque specs were provided, and the switch gear was seemingly good quality, as was the plastic casing. The bus bars linking the two outputs are designed so they stay in relatively easily even with the terminals open for terminating the tails, making installation easier. Would buy again. Review: Works isolates and protects electronic devices in the home - Good way to upgrade to the new UK regs Surge protection device should be fitted to new installations and recommended for existing unless you can prove otherwise with risk assessment which is more of a pain than just fitting one This is fitted in the meter box next to the cut out fuse bottom right of box leaving the top half of the box for the meter The isolator is double terminal on the live side only If you cannot isolate your supply other than with the cutout fuse I'd get this fitted by your energy supplier when they fit a new meter as your not allowed to pull the cut out fuse and national grid will charge 4 times the price The spd is connected by a bus bar in the inclosure and will need 10mm to 16mm earth cable to connect it to earth dependent on the impedance of your earth Once fitted the installation should be voltage surge protected this one has a green indicator on it after a few years and operations will need replacing once red shows can be replaced without opening enclosure as its module is push clipped into its base so can be squeezed and pulled and a new one pushed in I would also put a decal in the consumer unit this feeds warning that a spd is fitted in the meter box as if a sparky insulation resistance tests the circuit he may damage the unit and or get false readings the spd needs removing before the tests ## Features - ⚡ 100A Main Isolator – Provides safe and reliable isolation for electrical supplies during maintenance. 🛡️ Integrated SPD Protection – Helps protect connected equipment from damaging voltage surges and transient events. 🔌 4-Way Metered Supply – Compact design for managing multiple circuits with metering capability. ✅ 18th Edition Compatible – Suitable for modern installations requiring surge protection to BS 7671 standards. 🔒 Sealable Switch – Helps prevent unauthorised operation and improves safety. 🏗️ Durable Design – Reliable, space-saving solution for domestic, commercial and industrial applications. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08CZVY4CW | | Best Sellers Rank | 48,890 in DIY & Tools ( See Top 100 in DIY & Tools ) 270 in Power Strips | | Brand | WCED | | Circuit Breaker Type | Standard | | Circuit breaker type | Standard | | Country Of Origin | China | | Current Rating | 100 Amps | | Current rating | 100 Amps | | Customer Reviews | 4.6 out of 5 stars 60 Reviews | | Manufacturer | WCED | | Manufacturer Part Number | WEC440SP | | Model Number | WEC440SP | | Mounting Type | Wall Mount | | Mounting type | Wall Mount | | Number of Items | 1 | | Number of Packs | 1 | | Number of Poles | 4 | | Number of items | 1 | | Number of poles | 4 | | Voltage | 230 Volts (AC) | ## Product Details - **Brand:** WCED - **Circuit breaker type:** Standard - **Current rating:** 100 Amps - **Mounting type:** Wall Mount - **Number of poles:** 4 ## Images ![100A Metered Supply Isolator with Type 2 Surge Protection SPD, 4 Way Consumer Unit Distribution Board, Main Switch Enclosure for Electrical Installations - Image 1](https://m.media-amazon.com/images/I/51GBIMnXHXL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A decent quality solution for SPD and switch close to the meter. *by M***N on 3 November 2025* A nicely packaged solution offering a type 2 SPD that can be mounted where a normal isolator would be, so well within the 50cm of the origin of the installation from the regs.
