Detection Device
Product overview
MTAF1-32 Arc fault Detection Devices is consist
of small circuit breaker, tripping mechanism and arc
detection module. MTAF1-32 Arc Fault Detection Devices
has the function of short circuit protection,overload
protection and arc fault protection.It detects the arc
fault through the chip detection program, and if it is
confirmed as the fault arc, it will disconnect the power
supply and provide arc fault protection. According to
statistics the proportion of total fire in electric fire is
increasing year by year. In addition,seventy percent of
electrical fires are caused by faulty arcs. MTAF3-32 Arc
Fault Protection Devices can effectively avoid fire caused
by fault arc.
Product usage
MTAF1-32Arc fault Detection Devices is widely
used in rated current 32A and the following
household and similar communication circuits.
Arc fault protection unit of MTAF1-32 Arc fault
Detection Devices can detect and identify series arc
faults, parallel arc faults and ground arc faults. For
example:the old and damaged insulation layer of
line, wet air can cause arc faults phenomena. When
Arc fault Detection Devices detects that there is arc
faults exist ,it would be automatically tripping and
cut off the power supply.

Product characteristics
MTAF1-32 Arc fault Detection Device has the
function of arc fault protection , overload
protection and short circuit protection .
The rated voltage is 230V . The limit of action
discrimination as follows:
Test arc current
(Valid values)
Maximum
section time
The test arc current is the expected current in the test circuit.
Table 1
The small arc current below 63A runs down the limit value of the
MTAF1-32
arc fault Detection Device has the overcurrent
protection function of arc fault protection appliance.When the
circuit current exceeds the rated current of the product. The
MTAF1-32
bending deformation of the thermal tripping system
drives the main contact from the closed position to the
disconnection position so that the current is switched off. The
characteristics of overcurrent trip of
protection appliance is shown in table 3.
