Schneider Electric LV847926SP MasterPact MTZ2/3 Cable Interlock Plate Spare Air Circuit Breaker Accessory

The Schneider Electric LV847926SP is a mechanical cable interlocking adaptation plate supplied as a spare part for MasterPact MTZ2 and MTZ3 circuit breakers, fixed or drawout. It couples two breakers so that a mechanical interlock prevents both from closing at the same time. It is supplied with 1 instruction sheet in packs of 6.

Selection Notes

The LV847926SP couples exactly 2 devices, so it suits a simple two-breaker mutual interlock such as a main/tie or main/generator pair rather than a multi-source scheme. Because it uses a cable rather than a rigid rod, it allows more routing flexibility between breakers mounted further apart or on different panel sections; the LV847930SP rod interlock is the direct alternative where the two breakers sit close enough for a rigid connection. It fits both fixed and drawout MTZ2/MTZ3 breakers. Both the plate and the coupling hardware are included, so no separate cable or rod needs to be sourced.
