Square D | MHL26300V | Circuit Breaker | 300A | 2-Pole | 26300V

The Square D MHL26300V circuit breaker is built to protect high-demand electrical systems with precision and reliability. Designed as a two-pole protection device, it carries a robust 300 A rating and a voltage specification of 26300 V, making it a precise match for applications demanding solid, industrial-grade current interrupting capability. This is the exact OEM part you need when maintenance, retrofit, or replacement requires strict spec alignment with existing panels and enclosures.

Key specifications

• Amperage: 300 A
• Poles: 2-Pole
• Voltage rating: 26300 V
• Part number: MHL26300V
• Manufacturer: Square D

Why this MHL26300V stands out

• Exact-fit replacement: OEM compatibility ensures the same mechanical interface, mounting pattern, and electrical characteristics you rely on in your current installation.
• High-current protection: A dedicated 300 A capacity across two poles supports heavy-load circuits and balanced protection across both hot legs.
• Designed for retrofit and maintenance: If you’re upgrading or replacing aging breakers, this model reduces the risk of mismatch and unnecessary downtime.
• Reliability in demanding environments: Built to sustain repeated operation in industrial settings where consistent performance matters.

Ideal use cases

• Retrofits or replacements in commercial or industrial panels that require a 2-pole, 300 A protection device.
• Service entrances and distribution panels where exact-square D specifications are necessary to maintain protection schemes.
• Motor control centers or heavy-load feeder circuits that demand robust current interruption.

Compatibility and ordering tips

Note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

To ensure a seamless installation, verify that the panel or enclosure accepts the MHL26300V model and that the voltage and amperage requirements match your system. This model is the precise Square D solution when the existing configuration calls for a 2-pole, 300 A device with the specified voltage rating.
