ABB OS30FAJ12 - 30A, 3-Pole, Fused Disconnect Switch

ABB OS30FAJ12: 30A, 3-Pole Fused Disconnect Switch

The ABB OS30FAJ12 is a rugged fused disconnect switch engineered for safe, reliable electrical isolation in demanding industrial and commercial environments. With a 30A rating and three-pole design, it provides true three-phase isolation and dependable disconnection under load, supporting maintenance, testing, and service with confidence while helping protect personnel and equipment.

Key benefits that matter on the floor

• Three-pole isolation ensures all three hot conductors are safely disconnected, delivering complete system isolation for service and troubleshooting.
• Integrated fuse protection interrupts overcurrent automatically, guarding downstream equipment and reducing arc flash risk during maintenance.
• Lockout/tagout compatibility supports standard safety procedures, allowing technicians to secure power off with a padlock and tag before work begins.
• Durable, industrial-grade construction designed to withstand demanding environments and frequent operation cycles for long-term reliability.
• Easy integration into control panels and electrical rooms, making retrofit or new-install projects straightforward without sacrificing safety or performance.

Practical use cases

• Motor control circuits and drives up to 30A in manufacturing lines and packaging equipment
• Three-phase feeds for HVAC systems, compressors, and other utility equipment in commercial facilities
• Control panels for conveyors, robotics, and material handling where reliable isolation is critical
• Maintenance windows and service shutdowns that require secure, guaranteed de-energization

What makes the OS30FAJ12 stand apart

• Designed to deliver dependable disconnection under load, helping minimize downtime and keep maintenance workflows on schedule.
