Keep your specialised distribution boards, commercial installations, and legacy consumer units running safely with our immediately available stock of genuine MEM (Midland Electrical Manufacturing) 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 MEM catalog is updated regularly and designed to accommodate a diverse range of configurations, including:
- MEM MCBs & Legacy Breakers: High-quality miniature circuit breakers tracking single-pole, double-pole, and triple-pole layouts across legendary domestic and industrial lines—including classic Memera 2000 (grey 101MB, 101MC lines), Stab-lok compatible AB series, and modern Eaton-era MBH, MCH, and MDH series.
- MEM field-fit RCBO Pods & RCDs: Comprehensive earth-leakage devices featuring robust double-pole and four-pole RCCB blocks alongside specialized Memshield 2 modular field-fit RCD/RCBO pods (including the high-demand AH30, H30, MR30, and R30 ranges) spanning 10mA to 300mA sensitivities.
- MEM MCCBs & Heavy Switchgear: High-capacity moulded case circuit breakers and industrial control gear featuring the robust Memshield collection (MGL, MFL, MEL, and MFN series) and Exel TPN fuse switch disconnectors scaling from 16A up to heavy-duty 800 Amp benchmarks.
- HRC Fuse Carriers & Rewireable Fuses: Traditional physical circuit safety components, including authentic Memera cartridge carriers, clip-fit HRC holders (AC and MFM series), and classic rewireable fuse blocks (HN517 to HN526 lines) built for secure sub-panel maintenance.
- Control Gear, Enclosures & Accessories: Industrial-grade installation gear, including automated AA series contactors, fully isolated modular enclosures, low-voltage door bell transformers (AA2BT and AA5 lines), and authentic Memshield board door lock replacement kits.
- Advanced Circuit Safety: Reliable fault isolation across classic distributions, tracking versatile breaking capacities (from standard M3, M5, M6, 10kA, up to high-performance industrial 25kA, 36kA, and 65kA parameters) and distinct tripping characteristics (Curves B, C, D, and legacy Type 1, 2, 3, and 4 curves).
