Frequently Asked Questions about 169PLUS-10C-120VAC
What is the 169PLUS-10C-120VAC?
Part of the 169 series, GE Multilin's 169PLUS-10C-120VAC is a Motor Management Relay that manages, protects, and monitors medium to large motor system. The device has a number of advanced elements that reduce the need for auxiliary equipment and eliminate wiring costs.
What is the failsafe code and contact arrangement for the 169PLUS-10C-120VAC GE Multilin 169 Plus motor management relay?
As specified within the part number, the 169PLUS-10C-120VAC is not a drawout version that comes with a drawout case so that the relay can be removed without having to power off the entire relay. This option can have testing applications. In this case, the 169PLUS-10C-120VAC does not have a D/O designated in the part number and accordingly is not a drawout model. The failsafe code, contact arrangement, and CT information do not need to be specified at the time of order unless the relay is of the drawout version. The 169PLUS-10C-120VAC and other 169 Plus or 169 models have the option to field select those product specifications.
What are the additional inputs provided on a GE Multilin 169 Plus motor management relay, such as the 169PLUS-10C-120VAC, when compared to a 169 model?
The 169PLUS-10C-120VAC, as a member of the GE Multilin 169 Plus relays has additional input capabilities when compared to the 169 model. Both of the models (169 and 169 Plus) have supply power inputs (L, G, N), phase CT inputs, ground fault CT inputs, and 6 stator RTDs. In addition to those six stator RTDs, the base 169 model has two extra RTDS whereas the 169 Plus model has four extra RTDs. The 169 Plus model is further differentiated from the 169 model by including a spare input, a differential relay input, and a speed switch input. Both models have an external restart capability, a keyswitch for an emergency restart, and a programming access keyswitch or jumper.
