What makes the AC422R unique

• Designed for GE equipment: Built to integrate with GE switchgear and bus architectures, ensuring proper fit and electrical coordination.
• Fast-acting fusible protection: Activates at the rated current to isolate faults quickly, helping protect downstream equipment and minimize downtime.
• 4-pole configuration: Supports multi-conductor bus layouts common in 60A, 240V installations, delivering coordinated protection across involved circuits.
• Maintenance-ready: Specifically suited for scheduled maintenance, retrofits, and replacement when matching specs are required.
• Best-fit reference: The part number AC422R is the most reliable reference for compatibility checks before ordering.

Ideal use scenarios

• Maintenance of GE switchgear where fusible protection is required to restore or upgrade protecting devices.
• Retrofits to add or upgrade fused protection on 60A, 240V circuits within GE panels and bus assemblies.
• Replacement of a failing or degraded bus plug to minimize panel downtime and maintain rated protection.
• New installations that require precise 60A, 4-pole, 240V fusible protection in compatible GE systems.

How it works

The AC422R plugs into the GE bus assembly and houses fusible links that open when overload or fault conditions occur. This rapid interruption prevents excessive fault current from propagating through the panel, helping to safeguard transformers, motors, and control circuits. The 4-pole design aligns with multi-wire GE configurations, ensuring every relevant conductor receives synchronized protection.

Installation and compatibility tips

• Always confirm fit and ratings before ordering; the AC422R is the best reference for compatibility with GE equipment.
• Verify that your system is operating at 240V and that the protection level matches the 60A rating.
• Installation should be performed by a licensed electrician following all applicable safety protocols and local codes.
• Ensure you have the appropriate fuse links and mounting hardware specified for your GE panel or switchgear configuration.
• Store spare fusible links and maintain a small inventory to reduce downtime during planned maintenance or retrofits.

Engineered for reliability in industrial environments, the General Electric AC422R Fusible Bus Plug offers precise, field-ready protection that aligns with GE specifications. When you need a matching, resilient solution for maintenance, retrofit, or replacement in 60A, 240V configurations, this fusible bus plug is designed to deliver consistently to keep your electrical infrastructure running smoothly.
