damage, is reached.
The LVD is available in brown or grey (faceplate only). The nominal
dimensions are 6.60 inches high, 10.25 inches deep, and 2.2 inches or 5.85

used primarily in embedded applications.
The Low Voltage and Low Voltage Disconnect alarms are visually displayed
on the LVD unit and can also be monitored externally.
