HLMXD63B500 - 500Amp Circuit Breaker

HLMXD63B500 - 500Amp Circuit Breaker

When your job calls for a specific breaker, getting the details right matters more than flashy claims. The Siemens HLMXD63B500 is a 500A, 3-pole SENTRON molded case circuit breaker built on the LMD frame for electrical systems rated up to 600 VAC. It uses a fixed, non-interchangeable thermal-magnetic trip unit and provides an interrupting rating of 50 kAIC at 600V and 65 kAIC at 480V. The breaker is supplied without lugs installed, which is an important detail when matching it to an existing application. At 7.5 inches wide, 16 inches high, and 4.5 inches deep, its defined LMD-frame dimensions also make it easier to verify physical compatibility before installation. It meets UL 489 and IEC 60947-2 standards and carries a standard 40°C temperature rating. These breakers are built to last, but proper application still depends on confirming that every electrical and physical specification matches the equipment being serviced.

Key Features and Benefits

• 500A, 3-pole configuration: Designed for electrical equipment requiring a 500-amp, three-pole molded case circuit breaker.
• 600 VAC rating: Suitable for compatible systems operating at voltages up to 600 VAC.
• LMD frame: Provides a defined frame configuration for matching compatible existing equipment and installations.
• Thermal-magnetic trip: Uses a fixed, non-interchangeable trip unit for overcurrent protection according to the breaker's design.
• No lugs installed: The HLMXD63B500 is supplied without factory-installed lugs, an important consideration when planning a replacement.
• Known physical dimensions: Its 7.5" × 16" × 4.5" size helps maintenance personnel verify available space and physical compatibility.
• Recognized standards: Meets UL 489 and IEC 60947-2 requirements.
