Square D D322NRB 60A 3P 240V Safety Switch, NEMA 3R, Fusible | AmpState

The Square D D322NRB 60A 3P 240V Safety Switch is the reliable equipment disconnect you place at the point of use to keep maintenance safe and downtime short. Built to stand up to demanding industrial environments, this 3-pole, 240-volt safety switch uses a fusible configuration to provide clear, isolated power when needed and reliable protection during fault conditions.

Key benefits:

• NEMA 3R rated enclosure for dependable outdoor and semi-exposed installations, protecting against rain and external elements while still allowing safe access during service.
• Three-pole design delivers full-phase isolation, making it easier to de-energize equipment for maintenance, testing, or repair.
• 60 A, 240 V rating sets the right balance between performance and protection for motors, conveyors, and other industrial loads.
• Fusible configuration adds an extra layer of current protection and simplifies fuse coordination within your electrical panel or disconnect scheme.
• Exact part number compatibility – D322NRB ensures you’re ordering the right unit for maintenance inventories, panel builds, or replacements, reducing guesswork and downtime.
