File D10

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 non-fusible 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.
