The Square D NEL36700LS is a high-capacity circuit breaker engineered for demanding 3‑phase, 600V power systems. With a 700A rating and 3 poles, this unit delivers reliable overcurrent protection for heavy-duty industrial and commercial applications. Designed to align precisely with Square D’s NEL family specifications, it’s the ideal choice for maintenance, retrofit, and replacement projects where exact compatibility matters.

Key specifications

• Amperage: 700A
• Poles: 3‑pole
• Voltage: 600V
• Reference: Part number NEL36700LS (best compatibility reference)

What makes this breaker stand out

• Exact-fit for NEL-series panels: Built to match Square D’s NEL specifications, ensuring proper mounting, alignment, and electrical coordination within your panelboard.
• Three-pole design for balanced protection: Simultaneous interruption of all hot legs in a 3‑phase system enhances safety and minimizes arc-on conditions during faults.
• Durable construction for industrial use: Engineered to endure frequent cycling and the rigors of commercial and industrial environments while maintaining stable trip performance.

Ideal use cases

• Maintenance and service of existing 3‑phase, 600V distribution panels that require a 700A main or feeder breaker.
• Retrofit scenarios where an original NEL-series breaker is being replaced to restore exact electrical characteristics and protection curves.
• Replacement in legacy systems where the panel documentation references the NEL36700LS part number for compatibility.

Installation and compatibility tips

• Always confirm fit and ratings against your panel’s documentation before ordering. The NEL36700LS is best referenced by its part number for compatibility.
• Verify that your system is a 600V, three‑phase configuration to ensure the correct operation and protection level.
• Follow the manufacturer’s installation guidelines and torque specifications in the panel’s service manual, and ensure proper isolation procedures before servicing.
• If you’re replacing an existing breaker, compare the exact model and series (NEL) to avoid mismatches in trip characteristics or mounting geometry.

Designed for professionals who demand dependable, precise overcurrent protection in high‑current environments, the NEL36700LS offers a precise, durable solution when 700A, 3‑pole, 600V protection is required. Its precise compatibility and robust performance help minimize downtime and maintain safe, reliable electrical distribution.
