Key specifications at a glance

• Amperage rating: 100 A
• Voltage rating: 600 V
• Poles: 3-Pole
• Type: Non-Fusible Disconnect Switch
• Brand/Model: Siemens NF353H

Why choose a non-fusible design?

The NF353H provides immediate isolation without relying on internal fusing, simplifying re-energization after servicing and reducing maintenance complexity in routine shutdowns. Its 3-pole configuration ensures all live conductors are safely isolated, preventing neutral or ground carryover in multi-phase systems. This makes it an ideal fit for motor circuits, panel boards, and distribution feeders where quick, safe disconnection matters most.

Key benefits in real-world use

• Safe, lockable isolation: Compatible with standard lockout/tagout devices, helping you secure the circuit during servicing and ensuring worker safety.
• Reliable under load: Engineered to deliver dependable disconnection when circuits are energized or heavily loaded, reducing the risk of arcing and accidental energization.
• Durable, maintenance-friendly design: Built for continuous operation in demanding environments with straightforward maintenance and panel integration.
• Versatile installation: Suitable for control panels, switchgear, or feeder routes across industrial and commercial facilities.

Ideal use scenarios

• Maintenance and testing of three-phase equipment, motors, conveyors, and pumps.
• Safe isolation for panel replacements, wiring tasks, or upgrades in manufacturing plants and processing facilities.
• Emergency shutdown points in electrical distribution layouts where quick, reliable disconnect is essential.
