Meet the Square D NEF361200LIG circuit breaker, a robust 3-pole unit rated for 1200A at 600V. Crafted for demanding industrial environments, this breaker is purpose-built for maintenance, retrofit, and replacement projects, providing dependable protection for three-phase electrical systems.

• Amperage: 1200A
• Poles: 3-Pole
• Voltage: 600V
• Part number (best compatibility reference): NEF361200LIG
• Ideal use cases: maintenance, retrofit, and replacement in compatible Square D installations

Why this model stands out: a 3-pole design ensures simultaneous disconnection of all three phases, promoting safer shutdown of heavy three-phase circuits and helping maintain panel coordination. Built for reliable operation in service cabinets and industrial panels, it mirrors the performance characteristics you rely on in critical power feeds—so downtime is minimized when you need to isolate a fault or perform routine maintenance.

Who this is for: electricians, maintenance technicians, and system integrators working with square-denced, 600V three-phase panels that require a high-amperage, three-pole replacement or upgrade. It’s a practical choice for retrofit projects where existing equipment must match the same electrical ratings and physical fit.

Practical guidance for purchasing and installation: always confirm fit and ratings before ordering. The NEF361200LIG part number is your best reference for compatibility with your current panel or enclosure. If you’re aligning with a specific Square D catalog, use the exact part number to ensure a seamless replacement or upgrade.
