Motor Protection Retrofit Kits
Description
Littelfuse Startco retrofit kits are an excellent choice
for upgrading motor protection, providing current- and
temperature-based protection, metering, and data logging.
MPU-32-X69X
The MPU-32-X69X Motor Protection Retrofit Kit is designed
to replace GE Multilin 169, 269, and 369 relays. It includes
the MPU-32 Motor Protection Relay, MPU-CIM Current Input
Module, and optional MPS-RTD Temperature Input Modules,
which are pre-wired on a panel. The kit fits in the existing
space and typically can utilize existing current transformers
and wiring to simplify the upgrade procedure.
MPS-469X
The MPS-469X Motor Protection Retrofit Kit replaces the
GE Multilin 469 relay. It includes the MPS Motor Protection
System and optional RTD and differential modules mounted
on a panel that can be installed in the existing 469 cutout.
Existing current transformer and wiring can be utilized,
simplifying the upgrade procedure.
