Square D PQ3610G 100A 3P 600V Safety Switch, Plug-On, NEMA 1, Fusible | AmpState

The Square D PQ3610G 100A 3P 600V Safety Switch is a purpose-built equipment disconnect and isolation solution designed for reliable point-of-use control. With a plug-on design and NEMA 1 enclosure, this 3-pole, 100-amp fusible switch offers a clean, retrofit-friendly path to safer, more maintainable electrical systems in indoor, dry environments. If you need a consistent part number for upgrades or maintenance planning, the PQ3610G is purposefully crafted to fit that exact spec.

Key features that matter in the field

• Amperage and voltage: 100 A at up to 600 V, suitable for many industrial and commercial equipment disconnect needs.
• Three-pole (3P) design: Delivers balanced, reliable three-phase isolation for motors and controlled equipment.
• NEMA 1 enclosure: Indoor, dry environment protection that keeps control circuitry safe during maintenance and servicing.
• Fusible configuration: Provides overcurrent protection coordinated with your fuse strategy for precise protection and selective coordination.
• Plug-On installation: Streamlines retrofits and panel upgrades by simplifying mounting and minimizing additional wiring work.
• Manufacturer reliability: From Square D, a trusted name in electrical control and safety devices, with a part number designed for compatibility and repeatable stock ordering.

Why this safety switch stands out

Unlike generic disconnects, the PQ3610G is specifically chosen when a consistent part number matters for maintenance planning and retrofit programs. The plug-on feature reduces installation time, while the fusible design provides tailored overcurrent protection, helping you meet safety, reliability, and serviceability goals without reconfiguring existing control logic.

Ideal use cases

• Equipment isolation at the point of use in manufacturing floors, processing lines, and packaging systems.
• Retrofit projects where keeping the same part number simplifies ordering, stocking, and maintenance documentation.
• Maintenance planning for indoor, dry environments where quick disconnection and safe servicing are priorities.
• Service disconnects for motors and feeders that require a robust, three-phase safety switch with clear isolation.

Practical guidance and best practices

• Coordinate the fusible elements with your protection scheme to ensure proper selectivity and fault clearing.
• Confirm indoor use suitability with the NEMA 1 enclosure to ensure optimal performance in dry environments.
• When planning retrofits, leverage the plug-on design to minimize downtime and simplify future replacements.
• For compatibility and fit checks, rely on the PQ3610G’s specification alignment with typical Square D control panels and disconnect assemblies.
