Square D | MAP36900 | Circuit Breaker | 900A | 3-Pole | 600V

The Square D MAP36900 circuit breaker is built for dependable protection in demanding 3-phase power systems. Designed for maintenance, retrofit, and replacement projects, this 900A, 3-pole unit delivers reliable overcurrent protection when you need to align with exact specifications.

Key specifications

• Amperage: 900A
• Poles: 3-Pole
• Voltage rating: 600V

Why MAP36900 stands out

What sets this breaker apart is its precise alignment with established system requirements. It’s explicitly intended for scenarios where matching amperage, pole configuration, and voltage are non-negotiable—making it an ideal retrofit or replacement choice for panels that previously used a 3‑pole, 600V, 900A protective device. Use this part when the fit and ratings must match existing equipment exactly to maintain protection coordination and system reliability.

Ideal use cases

• Maintenance projects where a direct MAP36900 replacement is required
• Retrofit updates in older 3-phase installations needing 900A protection at 600V
• Equipment upgrades in commercial or industrial power distribution where matching specs is critical

Compatibility and ordering guidance

Before purchasing, verify that the existing panel or switchgear expects a 3-pole, 600V device at 900A. The part number MAP36900 is the most reliable reference for compatibility, helping to ensure seamless integration and continued protection without modification.

Practical tips for installation and use

• Cross-check the panel labeling for the required amperage, pole count, and voltage before ordering.
• Keep the MAP36900 as the primary reference when confirming fit to avoid mismatches with similar-looking models.
• Follow standard electrical safety practices and the panel manufacturer’s installation guidelines during replacement or retrofit.
