Square D | NEL1236G | Circuit Breaker | 1200A | 3-Pole | 600V

Square D NEL1236G circuit breaker — a high-capacity, reliability-focused protection device designed for demanding industrial electrical systems. Rated at 1200 A with a 3-pole configuration and a 600 V maximum, this unit is built to guard large three‑phase circuits against overloads and faults, keeping equipment running smoothly in mission-critical environments.

Key specifications

• Amperage: 1200 A
• Poles: 3-Pole
• Voltage: 600 V

Why this matters

When your system demands robust, space-efficient protection for heavy loads, the NEL1236G delivers. Its exact match to this part number ensures you’re selecting a like-for-like replacement or retrofit, reducing the risk of compatibility issues during maintenance or upgrades. In scenarios where downtime is costly, sticking to the specified 1200 A, 3-Pole, and 600 V ratings provides dependable protection for feeders, motors, and distribution circuits.

Ideal use cases

• Replacement or retrofit in large commercial or industrial panels
• Protection of high-current three-phase motor feeders
• Upgrading circuits that require a strict 1200 A, 3-Pole, 600 V specification

Compatibility and installation tips

Before ordering, verify the panel labeling and current protection requirements to confirm a precise fit. The NEL1236G part number is the most reliable reference for compatibility, helping you avoid misfits that can cause installation delays. If your current breaker is already the NEL1236G, you’re likely looking at a straightforward replacement. For upgrades from a different series, consult your panel’s documentation to confirm mounting, termination, and trip characteristics align with a 3-Pole, 600 V unit.

Practical benefits

• Consistent, reliable tripping behavior across all three phases, helping prevent phase-to-phase faults and equipment damage
• Simple, direct replacement workflow when the part number matches NEL1236G
• Enhanced protection for high-current loads in manufacturing, processing lines, and large-scale distribution

Choose the Square D NEL1236G for a trusted, high-current protection solution that aligns with your existing specifications, minimizes downtime, and preserves system integrity across demanding industrial applications.
