Westinghouse FDP326R - 600A, Fused Safety Switch

The Westinghouse FDP326R - 600A, Fused Safety Switch is engineered for reliable electrical isolation in demanding industrial and commercial settings. Its fused design provides immediate overcurrent protection while enabling safe, controlled disconnection under load—crucial for maintenance, service, and lockout/tagout procedures.

Why choose the FDP326R? Key benefits include:

• 600A maximum amperage rating for heavy-duty power distribution in panels and enclosures.
• Fused safety switch that adds a layer of protection by interrupting fault currents at the device level, reducing exposure and equipment damage.
• Safe isolation and lockout/tagout readiness built to support standard LOTO practices, ensuring technicians can work with confidence.
• Durable, long-lasting construction designed for industrial environments where frequent switching and rugged conditions occur.
• Reliable disconnection under load capability to safely de-energize equipment without risk, minimizing downtime.

Who needs this switch? Ideal for manufacturers, data centers, facilities managers, and service teams that require quick, secure isolation of heavy loads. It’s well-suited for motor control centers, distribution panels, and service entrances where robust protection and straightforward maintenance are priorities.

Practical use cases and scenarios:

• Routine maintenance on production lines where energizing equipment must be safely isolated before servicing
• Emergency fault isolation to quickly cut power and prevent escalation
• Scheduled lockout/tagout procedures during preventive maintenance and upgrades
• Integration into commercial and light industrial electrical distributions needing dependable disconnection under load

Compared to basic disconnects, the FDP326R provides integrated overcurrent protection and a safer, simpler path to de-energize equipment while maintaining compliance with safe-work practices.
