Allen-Bradley 194R-NJ100P3 - 100A, Disconnect Switch

The Allen-Bradley 194R-NJ100P3 is a high-performance disconnect switch purpose-built for safe, reliable electrical isolation in demanding industrial and commercial environments. With a focus on precise disconnection and robust durability, this 100A disconnect switch is designed to keep maintenance crews protected while keeping your operations productive.

Designed for real-world use, the 194R-NJ100P3 supports proper lockout/tagout procedures, giving technicians a secure way to lock the switch in the off position during service. When minutes matter, this design helps prevent accidental re-energization and reduces downtime caused by unsafe work conditions. In daily operation, it delivers dependable isolation under load, so you’re not left wondering if the circuit is truly disconnected.

Why this disconnect switch stands out

• 100A amperage rating — confident isolation for medium-to-high current circuits, especially in equipment panels and electrical rooms.
• Lockout/tagout readiness — built to integrate with standard safety procedures, helping teams meet compliance and protect workers during maintenance.
• Durable, industrial-grade design — engineered for longevity in harsh environments common to manufacturing floors and commercial facilities.
• Reliable under-load disconnection — maintains clear, decisive isolation even when circuits are live, reducing the risk of arc flash or unsafe re-energization.
• Straightforward integration — compatible with typical switchgear configurations and service panels used in professional electrical installations.

Ideal use cases

• Service shutdowns for manufacturing lines, packaging equipment, or material handling systems where safe power isolation is critical.
• Electrical rooms and control panels requiring a dependable disconnect with built-in safety procedures.
• Retrofits or upgrades where a robust 100A disconnect switch is needed to meet safety standards and reduce downtime.

Compared to generic isolation switches, the Allen-Bradley 194R-NJ100P3 delivers a concrete safety advantage: a proven combination of lockout/tagout compatibility and reliable disconnection under load, backed by the trusted reliability of the Allen-Bradley family. This means fewer safety headaches, lower risk during maintenance, and steadier uptime for your critical systems.
