Siemens GF223NR - 100A, 2-Pole, Disconnect Switch

The Siemens GF223NR is engineered for demanding industrial and commercial environments where safe electrical isolation matters most. This 100A, 2-pole disconnect switch delivers dependable disconnection under load and is designed to integrate with standard lockout/tagout procedures, helping teams keep maintenance safe and downtime minimal.

Key features and benefits

• 100A, 2-Pole isolation - reliably disconnects both live conductors to fully de-energize circuits.
• NEMA 3R enclosure - weatherproof and outdoor-ready, protecting the interior from rain, dust, and corrosion.
• Durable, long-term performance - built to withstand the rigors of industrial use, vibrations, and temperature fluctuations.
• Lockout/Tagout compatibility - supports established safety procedures for maintenance and service work.
• Easy integration - designed to fit into existing switchgear, panels, or distribution systems without compromising space or compliance.
• Safe disconnection under load - ensures reliable shut-off even when circuits are energized, reducing risk during servicing.

Ideal applications

Perfect for outdoor facilities, manufacturing floors, and commercial sites where dependable isolation protects personnel and equipment. Use the GF223NR as a main disconnect for feeders or as a dedicated isolation switch for machinery and power circuits up to 100A, providing clear, hands-off control during maintenance or configuration changes.

Why the GF223NR stands out

Compared with indoor or lower-capacity switches, the GF223NR blends a robust 100A rating with a rugged NEMA 3R enclosure, ensuring reliable performance in harsh weather and dusty environments. The 2-pole design guarantees complete isolation of both conductors, minimizing the risk of accidental re-energization. With Siemens’ proven reliability, this disconnect switch helps reduce downtime, simplify safety procedures, and extend the life of electrical systems.

Installation and care tips

Adhere to standard electrical codes and Siemens installation guidelines. Mount the GF223NR in an outdoor-rated enclosure or approved mounting location, verify proper torque on all connections, and schedule regular inspections to detect wear on contacts or the operating mechanism. Maintain clear access for safe operation and reinforce lockout/tagout practices according to site policy.

Choose the Siemens GF223NR for a dependable, safety-focused disconnect solution that delivers strong performance, easy integration, and peace of mind across demanding industrial environments.
