Square D | MAP36400V | Circuit Breaker | 400A | 3-Pole | 36400V

Square D MAP36400V Circuit Breaker is an OEM, high‑current protection device engineered for demanding three‑phase power systems. With a 400A rating and a 3‑pole design, this MAP36400V model delivers reliable, synchronized protection across all phases in industrial electrical distributions, retrofit projects, and replacement scenarios.

• Current rating of 400 A provides robust protection for large loads and feeders common in industrial environments.
• 3‑pole configuration ensures coordinated tripping across all three phases, maintaining system stability in balanced 3‑phase networks.
• Maximum system voltage up to 36,400 V supports high‑voltage distribution needs while preserving precise trip characteristics and safe interrupting performance.
• OEM reference means reliable compatibility with Square D panels and accessories, reducing the guesswork in replacements and retrofits.
• Ideal for maintenance, retrofit, and replacement projects where exact specs and form‑fit are critical to minimizing downtime and ensuring continued protection.

Why choose the MAP36400V for your system

Choosing an OEM MAP36400V means you’re prioritizing compatibility, predictability, and long‑term support. This is especially important when upgrading existing Square D installations or when replacing a failed unit in a high‑demand, three‑phase distribution network. The trip behavior, mounting footprint, and electrical characteristics align with original equipment, helping you avoid mismatches that can complicate service calls or lead to unplanned downtime.

Applications and use cases

• Retrofits in aging industrial panels where high current and three‑phase protection are required.
• New installations in facilities with 3‑phase high‑voltage distribution demands.
• Maintenance replacements to restore original protection standards without panel modification.
• Any project where a precise MAP36400V reference is necessary to ensure compatibility with Square D systems.

Compatibility and ordering note: Confirm fit and ratings before ordering. The part number MAP36400V is the best reference for compatibility to ensure seamless installation with your Square D equipment.
