Cutler-Hammer 35K - 200A, 3-Pole, Disconnect Switch

Meet the Cutler-Hammer 35K 200A 3-Pole Disconnect Switch—the rugged, code-ready solution for safely isolating large electrical loads in demanding industrial and commercial environments. Built to endure real-world use, this disconnect switch delivers a decisive, dependable disconnection under load, so maintenance and service work can proceed with confidence and minimal downtime.

Key to safe electrical maintenance, the 35K is designed to support proper lockout/tagout procedures. The ability to create a secure, verifiable isolation point means crews can lock a circuit in the off position and tag it for compliance, reducing the risk of accidental re-energization during service. This is alongside the core function of providing a clear, visible break in three-phase power, ensuring all three conductors are isolated together for complete circuit shutdown.

• 200A, 3-Pole configuration — suitable for three-phase circuits up to 200 amperes, delivering full-phase isolation for reliable service disconnects.
• Lockout/tagout ready — engineered to integrate with standard safety practices, helping you maintain OSHA-compliant maintenance procedures.
• Durable industrial build — designed for long-term service in busy commercial and industrial settings where safe isolation matters most.
• Under-load disconnection — capable of interrupting power reliably when equipment is still energized, reducing downtime during maintenance and emergencies.
• Simple operation — straightforward manual actuation that technicians can rely on for quick, safe shutoffs when needed.

Applications and Use-Cases

The Cutler-Hammer 35K excels wherever a robust, three-phase service disconnect is required. It’s an ideal fit for large motors, conveyors, pumps, and HVAC systems in manufacturing facilities, data centers, processing plants, and commercial complexes. Use it as a primary service disconnect for new installations or as a reliable shutdown point in existing switchgear and control panels. When routine maintenance or emergency servicing is on the schedule, this 3-pole switch provides a precise, verifiable de-energization point you can trust.

Safety, Compliance, and Peace of Mind

Safety and compliance are built into the design. With lockout/tagout compatibility, technicians gain a clear, auditable way to secure circuits during service. The ability to disconnect all three phases simultaneously reduces the risk of partial energization and enhances the overall safety of maintenance workflows. For facilities prioritizing reliable downtime planning and worker protection, the Cutler-Hammer 35K offers a dependable, straightforward solution you can rely on day after day.
