Westinghouse WFDN100-WESTINGHOUSE-BREAKER - 100A, 600V, 3-Pole, Disconnect Switch

Designed for harsh industrial environments, the Westinghouse WFDN100-WESTINGHOUSE-BREAKER 100A, 600V 3-Pole Disconnect Switch delivers reliable electrical isolation where safety and uptime matter most. This rugged disconnect switch is ready to support lockout/tagout (LOTO) procedures while providing a predictable, under-load interruption that keeps equipment secure and maintenance workflows flowing smoothly.

Key capabilities that stand up to demanding work

• Three-pole isolation: Fully disconnects all conductors for comprehensive protection during service or emergencies, ensuring a complete de-energization of equipment.
• 100A at up to 600V: Robust ratings designed for demanding three‑phase machinery without compromising performance or safety.
• NEMA 4 enclosure: Weather-resistant and dust-tight, suitable for indoor use or sheltered outdoor installs in challenging environments.
• Lockout/Tagout readiness: Built to integrate with standard LOTO practices, helping facilities meet safety regulations while preserving workflow efficiency.
• Load-break performance: Engineered to interrupt current reliably under load, reducing downtime and extending equipment life.
• Industrial-grade reliability: Westinghouse design combines durable construction with straightforward maintenance and serviceability.

Ideal applications

• Industrial floor equipment and motor control centers where quick, safe shutdown is essential.
• Commercial facilities with heavy‑duty pumps, conveyors, or HVAC systems requiring durable isolation points.
• Outdoor or semi‑exposed installations where a weather-resistant disconnect is needed.
• Maintenance routines that rely on lockout/tagout to protect technicians during servicing.
• Replacement or retrofits in existing switchgear where a standards‑compliant 3‑pole disconnect fits seamlessly.

What problems it solves

• Minimizes arc energy and the risk of accidental re-energization during maintenance with reliable disconnection under load.
• Protects against water and dust ingress to reduce corrosion and extend service life in harsher environments.
• LOTO compatibility ensures safety compliance without sacrificing maintenance speed or workflow.
