Square D | LCL26300 | Circuit Breaker | 300A | 2-Pole | 600V

Square D LCL26300 is a rugged, high‑current circuit breaker designed to protect heavy electrical systems with reliability. This 2‑pole unit delivers 300A capacity and a 600V rating, making it a strong choice for demanding commercial and industrial panels where consistent protection matters.

Built for maintenance, retrofit, and replacement projects, this breaker plugs into panels that require the exact specs of LCL26300. Its two‑pole design ensures both live conductors are interrupted simultaneously, providing coordinated fault protection and helping to guard equipment, wiring, and personnel.

Key specifications

• Amperage: 300A
• Poles: 2‑Pole
• Voltage: 600V
• Part number reference: LCL26300 (best compatibility identifier)

Why choose this Square D breaker

• Direct fit for panels that specify LCL26300, simplifying maintenance and retrofits
• Two‑pole protection for synchronized disconnection of both hot legs
• High‑voltage capability (600V) suitable for demanding distribution applications
• Clear, exact part identification helps prevent mismatches during replacements

Use cases and ideal applications

Ideal for facilities that require robust 300A, 2‑pole protection in 600V circuits—such as main feeders, distribution panels, and service equipment in industrial environments. Suitable for retrofit projects where older gear needs to be swapped for a like‑for‑like, spec‑accurate Square D solution to maintain consistent electrical protection standards.

Practical notes for ordering and installation

Before purchasing, verify that the panel or distribution board lists the LCL26300 as the required breaker and review all ratings to ensure compatibility. Remember: the part number is the most reliable reference for compatibility, so keep it handy when comparing replacements or planning retrofits.
