Square D | NE361000LSG | Circuit Breaker | 1000A | 3-Pole | 600V

Powerful protection for high-current, three-phase systems, the Square D NE361000LSG Circuit Breaker delivers reliable performance in maintenance, retrofit, and replacement projects. With a 1000A rating, 3-pole configuration, and a 600V maximum rating, this unit is built to safeguard feeders and equipment in demanding environments.

Key Specifications

• Amperage: 1000A
• Poles: 3-Pole
• Voltage: 600V
• Part reference: NE361000LSG

Why this model stands out

Unlike generic breakers, this NE361000LSG model is matched to Square D panels and distribution setups that require exact form factor and ratings. Its three-pole design addresses balanced three-phase loads and protects multiple conductors under a single device, simplifying panel protection and coordination with upstream protection devices.

Ideal Use Scenarios

• Maintenance outages: swap-in replacement for panels that previously used the NE361000LSG or compatible Square D units.
• Retrofit projects: upgrade older systems to handle 1000A, three-phase loads with minimal wiring changes.
• New installations in industrial facilities that require robust 3-phase protection up to 600V.

Fit, Compatibility and Safety

Always confirm fit and ratings before ordering. The NE361000LSG part number is your best reference for compatibility with Square D panels and bus assemblies. When integrating, ensure the enclosure, bus configuration, and trip characteristics align with the panel manufacturer’s recommendations. For safety, install only by qualified personnel following local electrical codes and proper lockout/tagout procedures.

Practical Tips

• Keep a cross-reference of part numbers for quick retrofit planning and avoid last-minute mismatches.
• Document your panel’s load profile to confirm that a 1000A, 3-Pole, 600V breaker provides adequate protection and fault clearance without nuisance tripping.
