Overview

GDDF -32 incorporating MCB and arc fault detection module, provides protection against
short ci 「 cuit, overload and arc fault. The incorporated arc fault module detects and identify
arc fault, which enables the product effectively disconnect the protected circuit against arc
fault.

Application

GDDF -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 GDDF -32 can effectively detect and identify arc faults
happened to different ci「cuitsconnected 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.

Indicating light function scheme

Instruction:When installing this product,disconnect the upper stream power supply, and then connect the LINE and LOAD as per following steps:

1.Turn on upper stream power supply, switch on the GDDF-32,the green indicating light flashes at time interval 0.6s and the product starts normal service

2.Switch on GDDF-32, connect load, press test button, the product trips, the green indicating light turns off and the yellow indicating light flashes once and goes off,which means product is at normal service.

3.During normal operation of a load, if GDDF-32 trips both green and yellow indicating light turns off, then first disconnect load and then switch the product handle to ON position.If the yellow indicating light flashes for 5-6 times and then turns off, last trip must have been caused by arc fault. If the yellow indicating light does not flash, last trip must have been resulted from overload or short circuit.

4.Confirmation about arc fault happened to the down stream circuit.After sequence 3 is performed,switch on GDDF-32, connect again the load to the product and try to poerate the load.If the yellow indicating light flashes once, the product trips and circuit gets disconnected, then arc fault must have occurred.Professional electrician is requested to investigate and correct the protected circuit

5.Contact the supplier or manufacturer for any abnormal service of product.

Installation

*Inspection should be carried out before installation to ensure that GDDF-32 is intact and flexible,the mark is in conformity with the usage requirement.

*A protective metal panel with earth connection or a panel made of insulated material shall be mounted as prevention against electric shock if an GDDF-32 is installed separately other than being installed in a distribution box.

*Any calibration on GDDF-32 by user is prohibited
