Exact-fit reliability for Square D panels

The LH36250CBA is identified by its part number, a crucial reference for compatibility with Square D panels and distribution gear. Before you order, verify the fit and ratings to ensure seamless integration with your current panelboard or switchgear assembly. Using the correct part number helps prevent mismatches that could affect protection performance or electrical clearance.

Key specifications and what they mean for your setup

• Amperage: 250 A — provides robust overcurrent protection for high‑load circuits without nuisance trips in normal operation.
• Poles: 3‑Pole — suitable for 3‑phase distribution, ensuring balanced protection across all three phases in a typical commercial or light industrial system.
• Voltage rating: 600 V — compatible with a wide range of medium‑voltage service environments common in many commercial installations.

Ideal use cases

This circuit breaker is well suited for:

• Maintenance and replacement projects where the existing equipment matches the LH36250CBA specifications.
• Retrofits that require upgrading or restoring three‑phase protection without changing the surrounding panel architecture.
• New installations in systems that operate at or below 600V and rely on a 3‑pole protection strategy to safeguard all three phases.
• Electrical service upgrades in mid‑to‑large commercial environments where panel downtime needs to be minimized with a like‑for‑like component.

Practical considerations for selection and installation

To get the most from this 250A 3‑pole 600V breaker, keep these points in mind:

• Compatibility first: The part number LH36250CBA is the best reference for matching with your Square D equipment. Always confirm fit and ratings before purchasing.
