Introduction
AFDD/AFCI Arc fault protectorIt is assembled by a miniature circuit breaker and an arc fault protection module, and has protection functions such as overload, short circuit, and arc fault protection.
AFDDArc fault protectorSuitable for communication 50Hz, rated voltage 230V, rated current to 63AIn the following lines, it is used to protect the overcurrent of the lines of buildings and similar purposes, and at the same time, it can detect many fire risks caused by the rupture of electrical devices or the aging of wires in advance, and protect against grounding arc faults, parallel arc faults and series arc faults. To a certain extent, the occurrence of fire safety accidents has been reduced, and the safety of people’s lives and property has been effectively protected.
