HMD63B500L - 500Amp Circuit Breaker Description
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.
