Circuit Breaker Repair by Brand
Every breaker family has its own failure pattern, its own spares situation and its own obsolescence story. These pages say what we do for each — current ranges and the discontinued generations the manufacturer no longer supports.
Schneider / Merlin Gerin Masterpact Repair
Masterpact M, NT, NW and MTZ. Hardened mechanisms, MCH gear motors, XF and MX coils, STR and Micrologic trip units — repaired, retrofitted and injection-tested.
DetailsABB SACE Emax Repair
First-generation Emax E1–E6 with PR111/112/113 and PR121/122/123, and Emax 2 with Ekip. Charging motors, coils, contacts and the trip-unit obsolescence problem.
DetailsSiemens 3WL / Sentron WL Repair
3WL frame sizes I–III, ETU15B to ETU76B. Secondary-connector wear, motor operators, auxiliary switch blocks and mechanism rebuilds.
DetailsEaton / Moeller IZM Repair
