MTAF1-32 Arc Fault Detection Device Overview

MTAF1-32 arc fault detection consists of a small circuit breaker, tripping mechanism, and arc detection module. MTAF1-32 have 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 fires is increasing year by year. In addition, seventy percent of electrical fires are caused by faulty arcs. MTAF3-32 arc fault protection device can effectively avoid fire caused by fault arcs.

MTAF1-32 AFDD Usage

MTAF1-32 AFDD are widely used in rated current 32A and the following household and similar communication circuits. arc fault protection unit of MTAF1-32 can detect and identify series arc faults, parallel arc faults, and ground arc faults. For example the old and damaged insulation layer of a line, wet air can cause arc faults phenomena. When Arc fault Detection Devices detect that there is arc faults exist, it would be automatically tripping and cut off the power supply.
