Restore manual-start capability on a Tornatech GPX or GPX+GPU electric fire pump controller with the MECTOR0157 R1 emergency handle system. This assembly covers contactor frames 3RT102, 3RT103, 3RT104, and 3RT105, and gives the operator a mechanical handle to force the motor contactor closed and start the fire pump when the automatic starting circuit is unavailable.
Common reasons to replace the handle system include a snapped or cracked handle, a mechanism that no longer returns or latches properly, or a handle that moves without engaging the contactor. Inspect the emergency start mechanism during routine controller service, and verify your controller's contactor frame is within the 3RT102–105 range before ordering.
MECTOR0157 is the R1 variant for Tornatech GPX and GPX+GPU electric fire pump controllers — distinct from our NOARK/Schneider E-handle assemblies (MECTOR0156 and MECTOR0734). Veteran-owned Cybertronic Controls stocks Tornatech replacement parts in Hammond, Louisiana; call 985-351-5681 with your controller model to confirm the right handle assembly.
