Material Compliance and Certifications

The Eaton HMDL3500 is UL Listed. This is an important point to verify when the equipment or installation calls for a circuit breaker carrying that certification.

No additional material-compliance designations were provided in the supplied manufacturer specifications, so they should not be assumed.

Where It Works Best

The HMDL3500 makes the most sense in existing electrical distribution equipment designed for an Eaton Series C HMDL breaker with an MDL frame. That makes it especially relevant for maintenance and replacement situations where the objective is to preserve the original equipment’s required breaker configuration rather than change it.
