• Upgrading industrial circuits in manufacturing, processing, or distribution facilities that demand reliable protection and quick fault isolation.

Fit and compatibility

Before ordering, confirm that your panel or distribution system is designed for a 700A, 3-pole, 600V device and that the NEP36500LI/NEP36700LI form factor matches your enclosure. The part number is the most dependable reference for compatibility, so cross-check it against your panel catalog or installation manual to avoid mismatches.

Practical installation tips

• Work with a licensed electrician to verify panel compatibility and correct trip characteristics for your specific load profile.
• Keep replacement breakers in their original packaging until installation to preserve contact surfaces and torque specifications.
• Document the exact part number in your asset management records to streamline future maintenance and replacements.
