Why this 900A, 3-Pole, 600V breaker stands out

In demanding electrical environments, you need a breaker that aligns exactly with your panel’s design and protection requirements. The NEL36900LIG is purpose-built for installations that require a precise 900 A current rating and three-phase coverage, ensuring reliable interruption across all phases when fault conditions occur. This reduces the risk of phase imbalances and equipment damage during overload events, delivering targeted protection where it’s most critical.

Ideal use cases

This breaker is the right choice for:

• Maintenance or retrofit work on industrial panels that originally spec’d a 900 A, 3-pole, 600 V protection device.
• Replacement of aging or non-standard breakers in heavy-load feeders for manufacturing lines, processing equipment, or large motors.
• Upgrading service feeders in commercial or industrial facilities where a consistent, high-current protection solution is required.

What you gain with the NEL36900LIG

By locking in the exact specifications needed, this breaker helps maintain system reliability and protection coordination. Rely on the definitive reference—its part number—to ensure there’s no guesswork in compatibility, stocking, or installation. Pairing the right breaker with your panel minimizes mismatches and unnecessary downtime during maintenance windows.

Practical installation considerations

• Before ordering, verify that your panel and bus configuration support a 900 A, 3-pole, 600 V device.
• Keep a correctly rated replacement on hand to reduce system downtime during planned maintenance or emergency outages.
• Consult with a qualified electrician or your panel manufacturer’s documentation to ensure proper mounting, wiring, and protection coordination.
