Part Numbering System

Shape installation and circuit diagram

Note: The main contact of the product has no polarity; the red wire of the coil is connected with the positive pole, and the black wire is connected with the negative pole, the auxiliary contact has no polarity to connect the white wire.

Current tolerance curve

Note: The above data is tested at 85℃ ambient temperature, Traverse area≥120mm². The data is for reference only, please do not use to select the fuse directly.

Pick-up / release voltage curve

The above data are tested by random sampling of coil volt. 12VDC product. The data is for reference only, (test qty:n=3)
