Product description
Shipping
The Square D MHP36400 circuit breaker is built to deliver reliable, high-capacity protection for demanding electrical installations. With a 400A rating, 3-pole configuration, and a 600V rating, this unit is designed for maintenance, retrofit, and replacement projects where exact specifications are essential. When you need a trusted, compatible component to safeguard three‑phase circuits, this MHP36400 breaker offers proven performance and straightforward interchangeability with compatible Square D panels.
Key benefits that matter in the field
- Exact electrical rating: 400 A, 3-Pole, 600 V, providing robust protection for heavy feeders in three‑phase systems.
- Direct replacement potential: Use the MHP36400 as a precise reference for compatibility in supported Square D panels and installations.
- Maintenance, retrofit, and replacement ready: Ideal for updating aging gear, expanding capacity, or restoring service after a fault in a 600V three‑phase network.
- Reliability you can trust: Square D offers dependable protection performance and long service life in industrial and commercial settings.
In practical terms, this breaker protects critical loads and feeders in environments that rely on stable, continuous power. It’s well suited for panel and distribution configurations where a 400A, 3-pole, 600V device is specified, helping to minimize downtime and maintain system safety during maintenance windows or upgrades.
Who this is for
Engineers, maintenance technicians, and panel assemblers working in industrial facilities, manufacturing floors, and commercial electrical rooms will appreciate having a ready-to-install, high-capacity breaker that aligns with exact specifications. It’s especially valuable for retrofit projects or when replacing a failed unit that requires the same 400A, 3‑pole, 600V characteristics to maintain electrical compatibility and protection performance.
Compatibility and installation notes
Before ordering, confirm fit and ratings on your specific equipment. The MHP36400 part number is the best reference for compatibility, so use it to verify panel model, bus configuration, and three‑phase acceptance. Ensuring the correct rating and physical form factor will help you avoid mismatches and installation delays.
