✅ Schneider Electric NW Mechanical Interlock – MasterPact NW Fixed/Drawout Interlocking Kit
The Schneider Electric NW Mechanical Interlock Kit is engineered to ensure safe and reliable mechanical interlocking between two MasterPact NW circuit breakers—whether fixed or withdrawable (drawout). This cable-based interlocking solution is crucial for preventing the simultaneous closing of two sources, guaranteeing operational safety in critical power distribution systems.
This kit includes:
Schneider Electric 47926: Mechanical interlocking fixture kit for MasterPact NW fixed or drawout breakers.
Schneider Electric 33209: A set of two 2.5-meter interlocking cables, compatible with both NT and NW breakers, fixed or drawout.
This solution is widely used in main/standby incomer schemes, bus coupler applications, and transfer systems where mechanical interlocks are essential.
