Square D | LCF26300 | Circuit Breaker | 300A | 2-Pole | 600V

Square D LCF26300 Circuit Breaker — a rugged 300A, 2-Pole, 600V protective device designed for reliability in maintenance, retrofit, and replacement projects. When your system demands solid overcurrent protection without panel redesign, this breaker delivers the exact specs you need.

Key specs and compatibility

• Amperage: 300A
• Poles: 2-Pole
• Voltage rating: 600V
• Part number: LCF26300 — the best reference for compatibility
• Brand: Square D

Designed for by-the-book replacement in Square D panels and legacy installations that specify the LCF26300 series. The exact part number matters for footprint, trip characteristics, and mounting arrangement, so confirm fit before ordering.

What problems does it solve?

When a 300A, 2-Pole, 600V circuit breaker fails or reaches end of life, downtime and unsafe wiring conditions follow. This LCF26300 model provides dependable overcurrent protection, helping to isolate faults quickly and protect wiring, motors, and controls from damage due to short circuits or overloads.

Ideal use cases

• Maintenance replacements in industrial service panels that require a 300A, 2-pole, 600V device.
• Retrofit projects where preserving original current rating and mounting footprint is critical.
• Replacement of failed breakers in heavy-load equipment, conveyors, presses, or large motors within 600V distribution systems.

Why this is a smart choice

In environments where panel compatibility and consistent tripping behavior matter, the Square D LCF26300 aligns with your system’s protection scheme without forcing panel redesign. Its 600V rating supports common industrial voltages, while the 2-pole configuration ensures simultaneous protection for both conductors in a circuit.

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