AFDD MCB Arc Fault Detection Device 2pole 6KA AFDD

Product Description

Overview

TMAFD1-32 incorporating MCB and arc fault detection module, provides protection against short circuit, overload and arc fault. The incorporated arc fault module detects and identify arc fault, which enable the product effectively disconnect the protected circuit against arc fault.

Application

TMAFD1-32, applicable to AC circuit with rated current up to 32A, is widely used for household and similar installations. The arc fault detection module of TMAFD1-32 can effectively detect and identify arc faults happened to different circuit connected in series, in parallel and to earth resulted from disabled insulation layer due to aging, damaging or high humidity. The product trips and disconnects a protected circuit upon detection of arc faults.
