Allen-Bradley 194R-NJ400P3 - 400A, 600V, 3-Pole, Fused Disconnect Switch

Allen-Bradley 194R-NJ400P3 is a 400A, 600V, 3-pole fused disconnect switch designed for industrial and commercial environments that require safe, reliable electrical isolation. This device is built to support proper lockout/tagout procedures and delivers dependable disconnection under load, ensuring long-term durability for demanding applications.

Key advantages:

• 400A amperage rating with a 600V maximum voltage capability, making it suitable for three-phase power systems in factories, warehouses, and processing facilities.
• Three-pole configuration provides balanced isolation for three-phase circuits and simplifies wiring in control panels and motor circuits.
• Fused disconnect protection combines circuit interruption with load isolation, helping protect equipment and personnel during maintenance or fault conditions.
• Lockout/Tagout readiness supports standard safety procedures, enabling safe servicing and compliance with workplace safety programs.
• Durable design built to withstand the rigors of busy industrial environments, delivering reliable performance over time.

Who this is for: maintenance teams, electrical engineers, and facility managers responsible for motor-driven lines, conveyors, pumps, and machine control panels. If you need a dedicated, code-compatible disconnect that you can trust to isolate under load while keeping maintenance personnel safe, the 194R-NJ400P3 is the choice.

Why choose this over generic disconnects: unlike simpler mechanical switches, this fused disconnect switch provides immediate, secure isolation with built-in protection, reducing the risk of unexpected re-energization during service and helping you meet lockout/tagout and safety standards with confidence.

Practical tips: plan your installation around three-phase layouts, verify compatible fusing elements, and group with appropriate control circuitry to minimize downtime during maintenance windows. For new builds or upgrades, this device helps streamline compliance and safety in one robust package.
