Siemens | RV425 | Fusible Bus Plug | 400A | 240V

Meet the Siemens RV425 Fusible Bus Plug—a purpose-built solution for quick maintenance, precise protection, and seamless retrofits in an industrial electrical distribution setup. This 400A, 240V fusible bus plug is designed to slot into compatible Siemens panels, delivering reliable overcurrent protection when you need it most.

Key specifications

• Amperage: 400A
• Voltage: 240V
• Part number: RV425
• Fit notes: Confirm fit and ratings before ordering. The RV425 part number is the best reference for compatibility.

What makes the RV425 unique

Unlike generic bus plugs, the RV425 is engineered to align with Siemens panel architectures, offering matched contact geometry and protective characteristics that ensure reliable operation and easier field swaps.

• Designed for maintenance, retrofit, and replacement where Siemens bus plugs of 400A/240V are required.
• Streamlined installation minimizes downtime during service events.
• Part number accuracy ensures you are ordering exactly the plug your panel needs.

Ideal use cases

Use in commercial buildings, data centers, and manufacturing facilities where Siemens distribution panels rely on a 400A/240V fusible plug to protect feeders and critical circuits. It's well-suited for retrofit projects upgrading older equipment or replacing failed bus plugs with a direct compatibility path via the RV425.

How it works

The RV425 is a fusible bus plug that integrates safety-rated protection into a plug-in module. When installed in a compatible Siemens bus assembly, it provides overcurrent protection at 400A and 240V, enabling rapid circuit isolation in the event of a fault while preserving system performance for ongoing operations.

Installation and compatibility tips

• Always power down the panel and follow lockout/tagout procedures before servicing.
• Verify the panel model and bus plug receptacle type to ensure the RV425 is a direct fit.
• Keep the RV425 part number on hand as the primary compatibility reference.

When you need reliable Siemens bus protection with assured compatibility, the RV425 is the precise choice for maintaining uninterrupted electrical service.
