How to ensure you’re choosing the right part

Always confirm fit and ratings before ordering. The LE36350LI part number is the most reliable reference for compatibility—verify that your panel accepts plug-in breakers in this form factor and that a 350 A, 3-pole, 600 V device matches your system requirements.

Practical installation tips

• Check panel labeling to confirm the acceptance of plug-in breakers with the same form factor.
• Power down the system and test for absence of voltage before removing or installing a breaker.
• Follow panel manufacturer torque specifications and mounting guidelines to ensure secure, reliable connections.
• Keep a spare LE36350LI on hand to minimize downtime during routine maintenance or unexpected replacements.
