Application notes PLMU Motor Protector SSAC Motor Protectors Some Faults Get Past the Competition Universal Three Phase Line Monitor The PLMU11 Stops Them All! The PLMU11 has the potential to replace almost 100 individual Full Protection for 3 Phase Motors line monitors on the market from nearly 20 separate manufacturers! n Phase Loss and Reversal Therefore, it’s no surprise that competitive brands don’t want this n Over and Under Voltage information to get out! Phase-to-phase voltages from 200 to 480V, n Unbalanced Voltage 50/60 Hz can be monitored including 380 to 415V, 50Hz. A unique micro-controlled, auto-ranging input makes this possible. The PLMU11 automatically senses the line voltage range. Easy-set How the PLMU Stacks Up Against the knob adjustments allow you to select the nominal set point, percent Competition of unbalance protection, and trip delay. Protection is provided even when regenerated voltages are present. Any maintenance organization or electrical distributor who services an industry that utilizes three phase voltages has to consider the PLMU11 as a vital addition to their stocking package; regardless of which brand they normally carry. There will always be unforeseen phase loss events caused by storms and vehicle accidents. The universal design of the PLMU allows you to reduce inventory cost while improving customer service. It makes sense to have the PLMU11 on the shelf, ready for the next emergency.
