Load management relay - LCR
Installed downstream of the main circuit-breaker, it compares the actual power consumption
of the system to a preset maximum permitted value. Additionally, the load management re-
lay prevents tripping of the main circuit-breaker by sequentially switching off one non-prior-
ity load when the preset threshold is exceeded. One red LED and an integrated buzzer indi-
cate the load OFF conditions. At preset time intervals, the device automatically attempts to
reconnect the previously disabled load.
Note: In unbalanced three phase systems same function of LCR can be implemented via DM-
TME multimeters. Digital outputs of the multimeter can be set to trip with an user defined
delay to switch off - by means of external contactors - non prioritary loads of arbitrary con-
sumption. See for details in Chapter 8 of Electrical installation solutions for buildings.
