Product Description

Application:
LMT53UV works together with LMM50H. It owns automatic voltage detector that will protect
circuit, either when it is over-voltage or under-voltage. It will reclose automatically as soon as
the circuit returns normal voltage. This is a very perfect solution to real circuit fluctuates, as it
is small size, and MCB is really reliable.
LMT53UV will only trip when voltage is abnormal, however, it won't trip or reclose when
MCB tripped due to overload or short-circuit faulty.
LMT53UV may also work with all our LMX accessories, such as LMX50U, which is under-
voltage protection auxiliary. They can be applied together for PV system.

Instruction on front panel
Auto : MT53UV will inspect the line voltage automatically, and will trip when the
voltage is either over or under normal rated voltage.
M a nu : MT53UV is set for manual mode, that is the device won't operate even
the voltage is abnormal;
