Siemens | RV325G | Fusible Bus Plug | 400A | 3-Pole | 240V

Meet the Siemens RV325G Fusible Bus Plug — a purpose-built protection module engineered for reliability in demanding electrical environments. With a 400A ampacity, a 3-pole configuration, and a 240V rating, this bus plug is tailored for maintenance, retrofit, and replacement projects where exact Siemens specifications matter.

Key specifications

• Amperage: 400A
• Poles: 3-Pole
• Voltage: 240V

What makes the RV325G stand out

Designed to integrate seamlessly with existing switchgear, the RV325G provides immediate, reliable overcurrent protection through a fusible mechanism embedded in the bus plug. This design minimizes downtime by enabling quick swaps during maintenance or retrofits while preserving the integrity and protection standards of your Siemens equipment. The 3-pole configuration supports balanced protection across three phases, helping you maintain stable operation in three-phase power systems.

Ideal use cases

• Maintenance and replacements in Siemens switchgear where a compatible fusible bus plug is required
• Retrofit projects to upgrade legacy panels to current protection standards without changing the bus assembly architecture
• Spare parts inventory for service teams maintaining critical industrial, commercial, or data-center infrastructure

Who benefits

• Facilities engineers and electrical contractors performing panel maintenance or upgrades
• Manufacturing facilities that rely on continuous, protected 400A distribution across three phases
• Service teams needing a reliable, compatible replacement part for Siemens equipment

Compatibility and ordering tips

Before ordering, confirm fit and ratings for your specific installation. The part number RV325G is the best reference for compatibility with Siemens bus assemblies. If you’re replacing an existing unit, verify that the amperage, pole count, and voltage match your current setup to ensure a seamless swap and continued protection of downstream equipment.

Choose the RV325G Fusible Bus Plug for dependable Siemens protection that aligns with your maintenance schedules and retrofit plans, helping you keep critical power distribution safe, compliant, and ready for operation.
