Square D MAB36400 Circuit Breaker is a robust 400A, 3-Pole protective device designed for demanding electrical installations. Rated for 600V, it's ideal for three-phase circuits in industrial and commercial settings, and is specifically suited for maintenance, retrofit, and replacement projects where exact compatibility is essential.

Key specifications

  • Amperage: 400 A
  • Poles: 3-Pole
  • Voltage rating: 600 V
  • Part number: MAB36400
  • Brand: Square D

Ideal uses

  • Maintenance and service of three‑phase distribution panels requiring 600V protection
  • Retrofit projects to upgrade or restore protection in existing Square D installations
  • Replacement for compatible panel boards where a 400A, 3-pole device is specified

Why it stands out

The MAB36400 combines a trusted Square D heritage with a straightforward, field‑replaceable format that simplifies upkeep of industrial power systems.
