Allen-Bradley 194R-HS4 - Disconnect Switch

The Allen-Bradley 194R-HS4 Disconnect Switch delivers rugged, reliable electrical isolation for demanding industrial and commercial environments. Engineered to support proper lockout/tagout procedures and provide a dependable disconnection under load, this switch helps maintenance teams work safely and keep downtime to a minimum.

Key benefits

• Industrial‑grade durability: robust construction built to withstand daily use in harsh facilities and deliver long service life.
• Under‑load disconnection: ensures a clean, decisive break in power even when equipment is energized during service.
• Lockout/Tagout readiness: supports compliant safety shutdowns and protects personnel during maintenance.
• Reliable isolation for critical systems: helps protect motors, feeders, and control circuits from accidental energization.

Ideal applications

The 194R-HS4 is well-suited for industrial and commercial settings where electrical safety and operational uptime matter. Use it for isolating power in motor control centers, panel boards, processing lines, conveyors, and other equipment that requires prompt, safe disconnection.

What sets it apart

Beyond a simple disconnect, the 194R-HS4 emphasizes rigorous safety alignment and durable performance. Its design prioritizes reliable isolation under load, robust construction, and compatibility with established lockout/tagout practices—features that translate to fewer risky workarounds and more predictable maintenance windows.

Practical tips

• Pair the 194R-HS4 with your facility's LOTO program to ensure compliant, verifiable shutdowns during maintenance.
• Schedule regular inspection of the switch contacts and actuator operation to preserve dependable disconnection over time.
• Document the isolation point in your electrical drawings so technicians know exactly where to isolate for servicing.
