Big decisions.
Look beyond the product name. These four checks help narrow the right configuration.
MISSION.A little precision. A smarter selection.
Fusible Disconnect Design
These general-duty switches provide a fusible disconnect arrangement. Match the fuse requirements to the exact switch and circuit application.
Pole & Wire Configuration
The group includes two-pole and three-pole configurations. Confirm the required pole and neutral arrangement for the electrical system.
Indoor & Outdoor Models
Choose a NEMA 1 indoor model or the corresponding NEMA 3R outdoor configuration. Match the catalog number to the installation environment.
Current Selection
The listed group covers 30A, 60A, 100A and 200A configurations. Check the required load rating and conductor range for the selected switch.
Before you select
Match the equipment. Check the fit.Load & Poles
Match the switch ampere rating, pole arrangement and system voltage. Check any motor-load requirements for the exact catalog number.
Circuit Protection
Confirm whether the selected switch is fusible or non-fusible. Coordinate the required protective devices with the electrical system.
Enclosure & Terminals
Match the environmental rating, conductor range and mounting requirements. Check neutral and grounding accessories separately.

Important Product Questions
Does a disconnect switch always provide overcurrent protection?
No. A non-fusible switch requires circuit protection elsewhere in the system. A fusible configuration must use the specified, correctly selected fuses.
Can indoor and outdoor models be selected by amperage alone?
No. Match enclosure rating, poles, voltage and conductor requirements as well as amperage. Use the exact catalog number for the installation environment.
What should be checked when replacing an existing safety switch?
Compare the complete catalog number, duty class, fusible arrangement, poles, voltage, enclosure and terminal requirements. Verify any neutral and grounding accessories.
Important Model Distinction
Ampere rating, pole arrangement, voltage, enclosure and fuse configuration depend on the selected switch. A matching current rating alone does not establish a suitable replacement.
