Westinghouse GFN423N Disconnect Switch, 100A, 3-Pole, 240V

Meet the Westinghouse GFN423N Disconnect Switch — a purpose-built solution for safe, reliable power isolation in industrial settings. Rated at 100 A with 3 poles at 240 V, this switch is engineered to interrupt all three phases cleanly, making it ideal for maintenance, service, and equipment replacement projects where quick, hands-on control is essential.

Key benefits and what it means for you:

• Three-pole, 240V operation ensures complete isolation of all conductors in a standard 240V circuit, reducing arc risk and enabling safer servicing.
• 100 A rating supports mid-to-heavy load applications typical in manufacturing floors, conveyors, pumps, and HVAC gear.
• Simple manual disconnect provides immediate power shutoff without tripping a breaker, helping minimize downtime during maintenance.
• Designed for industrial service, maintenance, and replacement — a dependable choice when you need a robust, field-ready disconnect switch.
• Compatibility at a glance — verify fit by part number and application requirements, using GFN423N as your reference for compatibility with your equipment.
• Trusted brand support from Westinghouse, with part-number clarity to simplify ordering and replacement in your control panel or switchgear.

What you can expect in practice:

• Safe, quick isolation during routine maintenance of motors, feeders, or pump assemblies in warehouses, factories, or distribution centers.
• Clear, unambiguous off-state for service personnel performing inspections or component replacements.
• Ease of inventory and maintenance planning thanks to a single, standardized disconnect switch for 3-phase 240V systems.

Tips for selecting and using the GFN423N:

• Double-check the part number (GFN423N) against your equipment specifications and electrical diagram to ensure a proper fit before purchase.
• Plan for lockout/tagout (LOTO) procedures; a mechanical disconnect like this makes compliant isolation straightforward.
• Consider enclosure compatibility and mounting space in your switchgear or control panel to accommodate a 3-pole 240V device.
