Square D | NE36700LS | Circuit Breaker | 700A | 3-Pole | 600V

Introducing the Square D NE36700LS circuit breaker—the reliable choice for protecting 3-phase, 600V electrical systems in maintenance, retrofit, or replacement projects. Built for demanding industrial environments, this 700A, 3-pole device delivers stable performance where it matters most.

Why choose NE36700LS:

• 700A continuous rating for heavy-load feeders
• 3-pole design to guard all phases in three-phase networks
• 600V maximum working voltage suitable for mid- to large-scale commercial and industrial panels
• Specifically intended for maintenance, retrofit, and replacement tasks that require exact spec alignment
• Best compatibility reference: part number NE36700LS ensures you’re matching the exact form factor and electrical characteristics

Compatibility and verification:

• Match the part number NE36700LS with your panel's documented requirements or label
• Confirm your system uses a 3-pole breaker and is rated for 600V
• Inspect mounting style and bus connection to ensure a proper fit within the existing enclosure

Practical use cases:

• Retrofit aging switchgear in manufacturing lines where a high-amperage 3-phase breaker is needed
• Upgrade feeders in large commercial facilities to safeguard against voltage sags and overloads
• Replace failed breakers in maintenance shutdowns with a direct, spec-matched substitute

Installation and care tips:

• Power down the panel and verify there is no voltage before handling the breaker
• Follow the manufacturer’s installation procedures to ensure a secure, code-compliant fit
• Keep the NE36700LS specification handy as the reference when ordering replacements or cross-referencing panel compatibility
