• Applications: Industrial control panels, maintenance and retrofit projects, panel replacements

Why choose the EH3020L for your project

If you’re upgrading an aging distribution setup or refreshing a panel with modern protection requirements, the EH3020L offers precise compatibility with 480V three-phase systems. Its three-pole design ensures balanced protection across all phases, reducing the risk of uneven fault currents and protecting connected motors and equipment from surges and short circuits.

Practical use cases

• Maintenance intervals where you need to swap like-for-like protection
• Retrofit projects that require exact 480V, 3-pole specifications
• Replacement of aging breakers in industrial control panels

Before ordering, confirm fit and ratings against your panel’s documentation. The EH3020L is the most reliable reference for compatibility, helping you avoid mismatches that can complicate installation or violate safety standards.
