Remote controlling device.
LNMA2-U2+O2 Over-voltage/Under-Voltage Tripper
·Rated voltage (Ue): AC 230V
·Rated insulating voltage (Ui): 500V
·Over-voltage tripping range: 270V±5%
·Under-voltage tripping range: 170V±5%
·Electro-mechanical endurance: ≥4000
·Mounted on the right side of circuit
breaker, actuate the combined device to
trip in case of under-voltage or over-
voltage, effectively prevent the device
from closing operation under abnormal
power voltage condition.
