HLD63B500L - 500Amp Circuit Breaker

HLD63B500L - 500Amp Circuit Breaker

When your existing electrical system calls for a specific breaker, getting the details right matters more than anything else. The Siemens HLD63B500L is a 500-amp, 3-pole SENTRON molded case circuit breaker built on the LD frame and rated for 600 VAC. It uses a thermal-magnetic trip unit with a standard 40°C rating and has an interrupting capacity of 35 kAIC at 600V and 65 kAIC at 480V. This particular configuration includes TA2J6500 lugs on both the line and load sides, with a conductor range of 3/0 AWG through 500 kcmil for copper and 4/0 AWG through 500 kcmil for aluminum. The breaker measures 7.5 inches wide, 11 inches high, and 4 inches deep, giving maintenance teams concrete dimensions to compare with existing equipment. It also meets UL 489 and IEC 60947-2 standards.

Key Features and Benefits

Material Compliance and Certifications

The Siemens HLD63B500L meets UL 489 and IEC 60947-2 standards. These standards are useful reference points when checking whether the breaker corresponds with the requirements of an existing electrical installation.

Where It Works Best

The HLD63B500L is best suited to maintenance and form-fit-function replacement applications where existing equipment requires a 500A, 3-pole LD-frame molded case circuit breaker with matching electrical and physical specifications. It can fit naturally into commercial and industrial maintenance situations involving compatible electrical distribution equipment where preserving the established breaker configuration is the goal.

One small detail deserves extra attention: the complete HLD63B500L catalog number matters. This configuration includes TA2J6500 lugs on both the line and load sides. When you're replacing an existing breaker, that connection arrangement should be checked along with the more obvious specifications.
