Allen-Bradley 194R-NJ100P3 - 100A, 600V, Fused Disconnect Switch

Allen-Bradley 194R-NJ100P3 is a purpose-built fused disconnect switch engineered for demanding industrial and commercial environments. With a 100A current rating and a 600V maximum voltage, it delivers reliable electrical isolation when you need to safely power down equipment, perform maintenance, or service critical systems.

Key to safe operations in busy facilities is proper lockout/tagout. The 194R-NJ100P3 is designed to support standard lockout/tagout procedures, giving technicians a clear, verifiable way to isolate circuits and prevent accidental energization during service tasks. Its fused design adds an extra layer of protection by interrupting fault currents at the source, helping to minimize arc flash risk and protect both personnel and equipment.

Why this matters in practice

In environments like manufacturing lines, material handling, and processing plants, reliable isolation and fault protection are non-negotiable. This fused disconnect switch:

• Provides dependable disconnection under load, so you can safely isolate circuits without risking unexpected re-energization.
• Offers rugged, durable construction tailored for continuous operation in harsh industrial settings.
• Integrates smoothly into control panels and power distribution setups, supporting streamlined electrical maintenance and safer startup sequences.
• Helps you meet safety compliance by enabling clear, enforceable lockout/tagout practices during routine servicing.

Ideal use cases

Consider the Allen-Bradley 194R-NJ100P3 for:

• Motor control centers and feeder circuits where reliable isolation is required during maintenance.
• Conveyor systems, pumps, and fans that demand quick, safe disconnect under load.
• Panel assemblies in OEM equipment where a robust, fuse-protected disconnect is part of the safety strategy.
