Square D | MP30H2 | Circuit Breaker | 3000A | 3-Pole | 600V

Meet the Square D MP30H2 circuit breaker — a purpose-built solution for demanding three-phase power systems. With a 3000A rating, 3-pole configuration, and a 600V operating envelope, this device is engineered for industrial environments where reliability and precise protection are non-negotiable. Whether you’re maintaining, retrofitting, or replacing protection in existing equipment, MP30H2 delivers the exact specs you need to keep critical loads safeguarded.

Why the MP30H2 is the right choice

• High-current reliability: 3000A rating handles significant, multi-phase loads while maintaining clear, coordinated protection across all three poles.
• Three-pole protection: The 3-Pole design ensures synchronized interrupting and balanced protection for each phase, reducing the risk of unprotected conductors during faults.
• 600V capability: Designed for commercial and industrial electrical systems that operate at up to 600V, aligning with typical mid-to-large panel requirements.
• Exact compatibility via part number: The MP30H2 part number is the best reference for ensuring a proper fit and ratings in your specific panel or enclosure.
• Maintenance, retrofit, and replacement: Ideal for upgrades or replacements where precise specifications are essential to maintain safety margins and panel coordination.

Practical use cases

Use MP30H2 when you’re upgrading legacy protection in large electrical rooms, replacement-in-kind for aging protection devices, or retrofitting systems that require a high-current, 3-pole, 600V solution. It’s particularly well-suited for industrial panels and switchgear where maintaining exact ampacity and phase protection is critical to prevent outages and equipment damage.

What to check before ordering

• Match the amperage rating (3000A), number of poles (3-Pole), and system voltage (600V) to your existing equipment and safety standards.
• Use the MP30H2 part number as the primary reference to verify compatibility with your enclosure and downstream protection scheme.
• Confirm that your upcoming replacement or retrofit preserves proper coordination with upstream devices and any existing protection philosophy.

How this protects your system

Choosing a device that precisely matches your electrical parameters minimizes unnecessary trips and protects downstream equipment from fault conditions. The MP30H2’s robust design supports sustained performance in demanding environments, helping reduce unplanned downtime and extend the life of your electrical infrastructure.
