HMD63B500L - 500Amp Circuit Breaker

HMD63B500L - 500Amp Circuit Breaker

When you need an HMD63B500L circuit breaker, the details matter. This Siemens MD-frame molded-case breaker is rated at 500 amps, 3-pole, and up to 600 VAC, with a thermal-magnetic trip unit. It has an interrupting rating of 50 kAIC at 600V and 65 kAIC at 480V. Another important detail is the lug configuration: the HMD63B500L comes with TA3K500 lugs on both the line and load sides, accepting copper or aluminum conductors from 1/0 AWG through 500 kcmil. The breaker meets UL 489 and IEC 60947-2 standards and uses the standard 40°C configuration.

Material Compliance and Certifications

The HMD63B500L meets UL 489 and IEC 60947-2 standards. Those are meaningful specifications when you're checking a breaker against the requirements of an existing installation or project.

Where It Works Best

The HMD63B500L makes the most sense for equipment that specifically calls for a 500A, 3-pole MD-frame molded-case circuit breaker with a thermal-magnetic trip mechanism and ratings matching this model. It's particularly relevant for maintenance and replacement work where preserving the original breaker configuration is important.
