50-164 - Switch

The 50-164 Switch is a rugged, compact fusible switch engineered for dependable on/off isolation and overcurrent protection in demanding industrial and commercial environments. Designed to fit where space is at a premium, this model provides solid motor disconnect capability, panelboard integration, and branch circuit protection—all in a maintainable package you can trust during daily operations.

Key Benefits

• Compact, maintainable design: A streamlined footprint reduces panel enclosure requirements, while simplified servicing minimizes downtime during inspections or fuse changes.
• Reliable isolation: Clear, positive off-state ensures safe mechanical disconnection for service and maintenance work.
• Integrated overcurrent protection: Built to interrupt fault currents, helping protect wiring and equipment from damaging surges.
• Industrial-grade durability: Constructed to endure the vibrations, dust, and wide temperature ranges common in manufacturing floors, processing plants, and large commercial spaces.
• Easy integration with common control schemes: Suits motor drives, panelboards, and branch circuits where a compact fusible switch is preferred over bulkier alternatives.

Ideal Applications

The 50-164 shines in environments where space is limited but reliability cannot be compromised. Use it as a motor disconnect on line-powered equipment, as a protective disconnect within panelboards, or to safeguard branch circuits feeding critical loads such as pumps, conveyors, fans, and processing equipment.

Why Choose the 50-164

• Space-efficient protection without sacrificing performance, making it a smart choice for retrofit projects or new installations with tight footprints.
• Maintenance-friendly operation facilitates quick fuse inspection and replacement, helping you minimize downtime during routine service or fault conditions.
• Clear separation of control and protection supports safer maintenance procedures and more predictable electrical behavior in complex systems.

How It Solves Real-World Problems

In active facilities, motors and other driven equipment require both isolating capability and protection from overcurrent events. The 50-164 provides a compact solution that lets you:

• Disconnect a motor quickly for safe maintenance without removing the switch from service
• Protect branch circuits from overloads, reducing the risk of insulation damage and downtime
• Consolidate control needs in panelboards, freeing up space for other essential equipment

Maintenance & Best Practices

• Regularly inspect fuse elements and connections to ensure proper seating and rated protection is maintained.
• Replace fuses only with the correct rating and type specified for the 50-164 to preserve protective performance.
• Keep the switch environment clean and free of excessive dust and moisture to extend life and reliability.
• Document inspection and replacement intervals to support preventive maintenance programs.
