GE SB321R - 30A, 240V, Fusible, Switch

GE SB321R is a 30A, 240V fusible switch engineered for reliable on/off isolation and built-in overcurrent protection in demanding industrial and commercial settings. This compact, maintainable solution combines fast, clear circuit disconnection with essential protection, helping machines and panels stay safe and operational.

Why the GE SB321R Stands Out

• Integrated fuse protection provides immediate overcurrent protection for downstream equipment without needing an external device.
• Compact and maintainable design simplifies installation in tight spaces and streamlines fuse replacement and servicing.
• Versatile application ideal for motor disconnects, panelboards, and branch circuit protection where a dedicated, easy-to-service switch is required.
• Reliable 30A, 240V performance supports a range of loads from small motors to control circuits in industrial environments.

Ideal Applications

Use the GE SB321R wherever you need a dedicated disconnect with built-in protection. It shines in motor disconnects on production lines, safeguarding sectional panelboards, and protecting branch circuits in commercial facilities. It also supports safety compliance during lockout/tagout routines and rapid circuit isolation during maintenance or emergencies.

Practical Installation Tips

For optimal performance, pair the SB321R with the appropriate fuse rating for your load and ensure wiring complies with local electrical codes. Its rugged, purpose-built design is suited to environments with frequent switching and motor start/stop cycles, helping protect equipment and reduce downtime. If you’re upgrading from a non-fused disconnect, the SB321R provides a streamlined, all-in-one solution for safe isolation and dependable protection.
