Keep your specialised distribution boards, commercial installations, and classic domestic consumer units running safely with our immediately available stock of genuine Wylex circuit protection components. As dedicated UK electrical supply experts, we specialise in sourcing both current and rare or obsolete modules, allowing you to find the exact replacements you need without facing costly panel retrofits.
Our online Wylex catalog is updated regularly and designed to accommodate a massive range of configurations, including:
- Wylex MCBs & Push Plug-Ins: High-quality miniature circuit breakers tracking single-pole and triple-pole layouts across legendary modern and heritage lines—featuring the NHXB, NSB, PSB, and NB collections, specialized partner Stotz or ABB variants, and traditional retrofit SK push plug-in modules scaling up to 63 Amp load thresholds.
- Wylex RCBOs & Advanced AFDDs: Comprehensive earth-leakage and fault defense devices, featuring compact single-module or double-pole RCBO lines (including NHXS, NHXSBS, NSBS, and PSBS series matching Type A or Type AC patterns) alongside modern dual-protection Arc Fault Detection Devices from the NXSB series.
- Wylex RCCBs & Time-Delayed RCDs: High-sensitivity residual current devices available across double-pole and four-pole distribution setups, featuring standalone high-sensitivity WRS, WSES, and WES collections alongside heavy-duty 100 Amp WRMT time-delay RCD modules tracking 10mA up to 100mA earth-leakage parameters.
- Wylex Industrial MCCBs & Switches: High-capacity moulded case circuit breakers built for three-phase commercial installations, featuring the robust Loadline AA and NHGPCB portfolios alongside double-pole or four-pole main switch disconnectors scaling from 63A to heavy-duty 225 Amp benchmarks.
- Traditional Fuses & Control Gear: Classic electrical protection components, including rewireable push plug-in fuse wire carriers (color-coded in white, blue, yellow, and red variants) paired with standalone NSC-type cartridge HRC holders, Type 2 transient surge protection devices (SPDs), modular enclosures, and rail-mountable doorbell step-down safety transformers.
- Advanced Circuit Safety: Reliable fault tracking across varied breaking capacity parameters (from standard 3kA, 4.5kA, 6kA, 10kA, up to industrial 25kA benchmarks) and a complete array of tripping characteristics (Curves B, C, D, and legacy Type 1, Type 2, or Curve K settings).
