Square D | MA367001021 | Circuit Breaker | 700A | 3-Pole | 600V

Square D MA367001021 Circuit Breaker is a robust protective device engineered for high-demand electrical environments. With a 700 A rating, a 3-pole configuration, and a 600 V maximum system voltage, this breaker delivers reliable interruption and enhanced safety for your three-phase power distribution.

Designed for maintenance, retrofit, and replacement projects where exact specs matter, the MA367001021 pairings with existing Square D infrastructure to ensure seamless integration and predictable trip behavior across your distribution system.

Key specifications

• Amperage (continuous rating): 700 A
• Poles: 3-Pole
• Voltage: 600 V

Why this model stands out

• 3-pole design provides synchronized protection across all three phases, helping to prevent uneven loading and potential equipment damage in three-phase networks.
• High-current capability makes it suitable for upgrading or replacing older systems that require a robust 700 A protection device without changing the surrounding panel architecture.
• Exact part-number compatibility (MA367001021) simplifies sourcing and reduces the risk of mismatched components during replacements or retrofits.

Use cases and ideal applications

• Retrofit projects in commercial or industrial panels where a 700 A, 3-pole, 600 V protection device is required.
• Maintenance replacements to restore original protection specifications after a fault or component failure.
• New or upgraded installations that demand precise compatibility with Square D systems while delivering reliable three-phase protection.

Compatibility and installation notes

Important compatibility reminder: Confirm fit and ratings before ordering. The part number MA367001021 is the best reference for compatibility, helping ensure your panel, bus configuration, and downstream circuits match the device’s specifications.

Practical tips for best results

• Double-check the panel catalog number and existing protection scheme to confirm that a 700 A, 3-pole, 600 V unit is the correct replacement.
• When planning a retrofit, map the downstream feeders and breakers to verify coordinated tripping and safe shutdown sequences.
• Store and handle the breaker carefully prior to installation to prevent mechanical damage that could affect trip performance.
