HMDL3450L - 450Amp Circuit Breaker Description
HMDL3450L - 450Amp Circuit Breaker
When your existing electrical system calls for a specific breaker, getting the details right matters. The Eaton HMDL3450L is a 450-amp, three-pole molded case circuit breaker from the Series C product family. Built on the MDL frame, this complete HMDL breaker features a T186 trip type and is rated for operation at 50–60 Hz. Its interrupt ratings are 100 kAIC at 240 VAC and 65 kAIC at 480 VAC. Those specifications make the HMDL3450L a practical choice for maintenance and replacement applications where the existing equipment requires this breaker type, frame, and pole configuration, as well as this electrical Rating.

Material Compliance and Certifications
The HMDL3450L is UL Listed, giving contractors, maintenance teams, and facility personnel a clearly documented certification to reference when evaluating the breaker for an application.
The supplied manufacturer information does not identify additional material-compliance certifications, so none are assumed here.
Where It Works Best
The HMDL3450L makes the most sense in existing electrical distribution equipment designed to accept an HMDL Series C breaker with an MDL frame. It's especially relevant when maintaining legacy equipment, and the goal is to replace a breaker while staying with the required form, fit, and electrical characteristics of the original application.
