Square D | NW20H2 | Circuit Breaker | 2000A | 3-Pole | 440V

Meet the demanding needs of large-scale electrical distribution with the Square D NW20H2 Circuit Breaker. Built for reliability in industrial environments, this 3-pole, 2000A breaker is designed to protect high-current, three-phase systems rated at 440V, helping keep feeders and equipment safe from overloads and faults.

• Amperage: 2000A
• Poles: 3-Pole
• Voltage: 440V

Fit & Compatibility

When accuracy matters, the NW20H2 part number is your best reference for compatibility. Before ordering, confirm that the breaker’s ratings align with your panel or switchgear requirements and that the form factor matches your enclosure. Square D NW20H2 is specifically suited for retrofit, maintenance, and replacement projects where matching specs is essential.

Ideal Use Scenarios

• Maintenance and retrofit of industrial power distribution panels that run on 3-phase, 440V systems
• Replacement in legacy installations where a 2000A, 3-pole, 440V breaker is required
• Upgrading protection in manufacturing facilities, data centers, and large commercial or utility environments with heavy electrical loads

Why NW20H2 Stands Out

• Brand assurance: Square D (Schneider Electric) lineage supports consistent performance with compatible panels and accessories
• High-current capability: Specifically engineered to interrupt and protect circuits handling substantial load currents
• Clear compatibility reference: The NW20H2 designation is the definitive guide for matching your equipment’s requirements

Practical Tips for Installation and Ordering

• Verify panel model, enclosure type, and rating sheets to ensure the NW20H2 is the correct replacement part
• Engage a qualified electrician or electrical technician for installation, and follow all safety standards and lockout/tagout procedures
• Keep spare parts on hand for critical 2000A, 3-pole breakers to minimize downtime in maintenance windows

The Square D NW20H2 Circuit Breaker is purpose-built for robust, high-current, three-phase protection at 440V. Use this part when you need a precise, reliable replacement that aligns with your existing Square D infrastructure and ensures continued protection for your most demanding electrical loads.
