ABB OS30FAJF30 - 30A, Fused Disconnect Switch

The ABB OS30FAJF30 is a purpose-built 30A fused disconnect switch designed for demanding industrial and commercial environments where safe electrical isolation is essential. This compact, robust device combines fuse-protected protection with a straightforward disconnect mechanism to deliver reliable power separation when you need it most.

• Integrated overcurrent protection — replaceable fuses provide immediate protection for motors, feeders, and control circuits, simplifying wiring and reducing the need for separate protective devices.
• Lockout/tagout compatibility — engineered to support proper lockout/tagout procedures, enabling authorized personnel to secure equipment during maintenance and testing.
• Dependable disconnection under load — designed to interrupt circuits reliably even when equipment is energized, helping maintenance crews isolate circuits safely and efficiently.
• Rugged, durable construction — built to withstand the rigors of industrial environments, delivering long service life with minimal downtime.

Ideal applications

Best suited for service disconnects and electrical isolation in motor control centers, manufacturing lines, HVAC and process equipment, power distribution panels, and generator connections. With a 30A rating, it’s a practical solution for medium-load circuits where dependable isolation matters.

Why this fusion of protection and isolation matters

By combining fusing with a disconnect in a single unit, the ABB OS30FAJF30 streamlines installation and maintenance. You gain clear fault protection alongside straightforward maintenance access, reducing the coordination required between separate protective devices and isolation switches.

Maintenance, safety, and best practices

• Always follow established lockout/tagout procedures before servicing equipment.
• Inspect fuses and the disconnect mechanism regularly; replace fuses with the same 30A rating and type as specified.
• Ensure the disconnect remains accessible and clearly labeled to minimize downtime during maintenance.
