The D10 disconnect switch features high I²T rating, longer contact life, visible contact
indication, fuse-mounting flexibility, dead-front construction, and auxiliary interlocks.
A complete installation includes a D10 disconnect switch, D11 handle operator, and D12
fuse clip kit. The D10 accepts Class H, K, J, or R fuses, or can be used for nonfusible
applications. The D10 disconnect switch is operated by a cast metal handle operator that
is lockable in the Off position and defeatable in the On position.
