Key specifications at a glance

• Model: SLVBR4640
• Amperage: 200A
• Voltage: 600V
• Phase: 3-Phase
• Fusible: Fusible (protects and disconnects in one unit)

Why this fusible switch matters

Choosing a fusible switch like the SLVBR4640 means you get a single, purpose-built device that combines isolation and protection. The integrated fuse protection minimizes wiring complexity and reduces the number of components needed to safeguard critical equipment. Its compact footprint makes it well-suited for panelboards and electrical rooms where space is at a premium, while its maintainable design streamlines fuse replacement and routine service.

Ideal use cases

• Motor disconnects in equipment rooms, mechanical spaces, and control panels
• Main or sectional protection for panelboards in commercial or light industrial facilities
• Branch circuit protection where a straightforward, reliable fusible switch is required

What sets it apart

Unlike standalone switches or less robust protective devices, the Siemens SLVBR4640 delivers a proven combination of switching reliability and fuse-based protection in a single, compact unit. Built for environments that demand durability and ease of maintenance, it supports straightforward integration with existing Siemens control and electrical distribution systems, helping facilities reduce component count and simplify procurement.

Practical considerations and setup tips

• Ensure system voltage and load align with the 600V, 3-phase 200A rating to maintain safe, reliable operation.
• Plan for periodic inspection of fuses and switching contacts as part of standard electrical maintenance to prevent unexpected downtime.
• Use in configurations where clear isolation (when opened) and protection (via fuses) are both required for motor and circuit protection strategies.
• Coordinate with enclosure sizing and wiring practices to maximize the compact, space-saving benefits of the unit.

Designed for electrical professionals who prioritize reliability, ease of maintenance, and precise protection, the Siemens SLVBR4640 is a practical choice for motor control centers, service panels, and other installations where dependable 3-phase, 200A protection at 600V is essential. It’s a durable, purpose-built solution that helps keep machinery protected and systems running smoothly.
