Siemens CFS363J - 100A, Fusible, Disconnect Switch

Siemens CFS363J — 100A Fusible Disconnect Switch is a robust isolation solution designed for reliable on/off control and overcurrent protection in demanding industrial and commercial environments. With a compact, maintainable design, this unit is ideal where space is at a premium and quick service is essential.

Key advantages

• 100 A rating provides strong protection for motor loads and branch circuits
• Fusible protection built into the switch for immediate fault isolation
• Compact footprint helps you fit disconnects in tight panels and enclosures
• Maintenable design supports straightforward fuse replacement and routine servicing
• Versatile installation suitable for motor disconnects, panelboards, and branch circuits

Why this matters for your system

Having a single, fusible disconnect switch at the service point reduces component count, simplifies wiring, and accelerates maintenance. The fuse element provides local overcurrent protection, so when a fault occurs you can safely isolate the circuit and protect downstream equipment. This is especially beneficial for start-up-heavy motor loads and circuits where swift, clear isolation is required for safety and downtime reduction.

Ideal use cases

Use the CFS363J in environments where a compact, fusible disconnect is needed to protect motor circuits, panelboards, and branch circuits. It’s well-suited for applications in manufacturing floors, commercial facilities, and other spaces where space constraints and reliability are key considerations.

Installation and best practices

Pair the CFS363J with the appropriate fuse type and rating for your specific load. Ensure proper installation following local electrical codes and Siemens guidelines to maximize protection, reliability, and ease of maintenance.
