FAQ

What type and size of fuse is compatible with the A9N15651?

This holder is designed for cylindrical fuses of size 10.3 x 38 mm. It is compatible with fuse types such as gG (up to 25A) and aM (up to 16A) as indicated on the device label.

Can this fuse disconnector be used in DC applications?

While primarily rated for AC (500V~), some fuse disconnectors can be used in DC circuits at a derated voltage. It is crucial to consult the official Schneider Electric datasheet for specific DC voltage ratings and application guidelines before use.

What is the breaking capacity of this device?

The breaking capacity is determined by the installed fuse, not the holder itself. The holder is rated to withstand the energy let-through of a fuse clearing a fault. Always install a fuse with a breaking capacity (e.g., 100kA) suitable for the prospective short-circuit current of the installation.
