Cutler-Hammer DG223NRB - 100A, Safety Switch

Meet the Cutler-Hammer DG223NRB—a 100A safety switch engineered for dependable electrical isolation in demanding industrial and commercial environments. When maintenance or servicing is required, this safety switch provides a clear, lockable disconnect that aligns with lockout/tagout procedures, keeping personnel safe and operations compliant.

Key strengths that make a real difference:

• 100A electrical isolation supports standard line loads in equipment rooms, machine controls, and distribution panels.
• Dependable disconnection under load ensures equipment is safely isolated even if circuits are energized, reducing risk during maintenance.
• Lockout/Tagout readiness integrates with standard safety practices, helping facilities stay compliant and protect workers.
• Rugged durability built to withstand industrial environments, with a robust mechanism and sturdy enclosure for long service life.
• Easy integration fits common control panels and electrical layouts, streamlining retrofits and new installations alike.

Ideal for plant maintenance teams, electrical contractors, and facilities managers responsible for safe power control in manufacturing floors, warehouses, service bays, and HVAC and other commercial systems. If you need a reliable safety switch that provides precise isolation when you need it and remains dependable for years of use, the DG223NRB is designed for you.

Use cases:

• Shut down production lines for scheduled maintenance with confidence that the line remains de-energized.
• Isolate motor starters, control panels, or power feeders during troubleshooting or repair work.
• Implement consistent safety protocols across multiple workstations or machines with a uniform safety switch solution.

Why this model stands out versus other isolation options? It emphasizes under-load disconnection reliability and lockout/tagout compatibility—two critical factors that minimize downtime and protect workers during service windows.

Practical tips to get the most from your DG223NRB:

• Pair with a compliant padlock and tag to enforce lockout/tagout, ensuring only authorized personnel can restore power.
• Document switch position and status in your facility’s safety log to support audits and safety reviews.
• Test the safety switch during scheduled maintenance to confirm proper operation and legible labeling.
