Need Help Choosing?
Send us the manufacturer, part number, voltage, amperage, fuse requirement, pole configuration, handle style, shaft length, enclosure information, quantity, or project specification.
Choose disconnects based on protection, rating, mounting, and operation
Product selection depends on system voltage, current rating, number of poles, fusible or non-fusible operation, enclosure or panel mounting, handle location, shaft length, lockout needs, and connected equipment.
Fusible vs. Non-Fusible Disconnects
Non-fusible disconnects provide manual switching and isolation, while fusible disconnects also accommodate fuses for overcurrent and short-circuit protection.
- Manual equipment isolation
- Fusible and non-fusible configurations
- Single- and multi-pole designs
- Machinery and motor applications
- Industrial and facility power systems
Door-Coupled Operation
Door-mounted handles and operating shafts allow an internal disconnect to be operated from outside an enclosure while supporting interlocking and lockout functions.
- External rotary handles
- Red/yellow and black handle styles
- Adjustable operating shafts
- Door interlock and defeater options
- Padlockable operating mechanisms
Accessories & System Completion
Compatible accessories help complete the disconnect assembly, support indication and control, protect terminals, adapt conductor connections, and replace damaged components.
- Auxiliary and signaling contacts
- Terminal shields and covers
- Lugs and conductor accessories
- Mechanical interlocks
- Mounting and replacement components
