NEMA-Style Door-Mounted Disconnect Switches (D10)
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.

Features and benefits

• High I(2) T rating – This switch meets automotive and heavy-industry requirements.
• Longer contact life – Quick-make, quick-break, cam-trip, and spring-loaded action throws the switch into the ON position under pressure. This provides a quick-break when switching to the OFF position. The double-break contact principle also assures longer life and exceptional interrupting capacity.
• Visible contact indication – Clear ON and OFF markings plus actual contact positions are both visible through pole “windows.”
• Fuse-mounting flexibility – Fuse clips are mounted on top of the switch, providing a compact unit. Interchangeable fuse-clip kits are available for quick adaptation to other ratings.
• Dead-front construction – When the switch is in the OFF position, all visible current-carrying parts are de-energized, thus providing additional safety for maintenance electricians.
• Auxiliary interlocks – One- or two-pole interlocks can be added to the disconnect switch when required.
