HLMD63B500 - 500Amp Circuit Breaker

HLMD63B500 - 500Amp Circuit Breaker

Need a 500A LMD-frame breaker for an existing installation? The Siemens HLMD63B500 is a 3-pole SENTRON molded-case circuit breaker rated for 600 VAC, with a thermal-magnetic trip unit and the physical configuration required for compatible LMD-frame equipment. If you're replacing a breaker already in service, matching the catalog number is a good starting point—but don't stop there. Check the frame, amperage, poles, voltage, interrupting rating, trip type, lugs, wire range, and dimensions against the equipment requirements.

Key Features and Benefits

• 500A, 3-pole configuration – Made for compatible three-phase applications requiring a 500-amp breaker.
• Rated for 600 VAC – Fits systems designed around this voltage and breaker configuration.
• Thermal-magnetic trip – Uses a thermal-magnetic trip design for overcurrent protection.
• LMD frame – An important detail when matching the physical and electrical characteristics of an existing breaker.
• TA3K500 lugs included – Load-side lugs accommodate the specified conductor range.
• Copper or aluminum conductors – Accepts 1/0 AWG through 500 kcmil Cu/Al wire.

Material Compliance and Certifications

The HLMD63B500 meets UL 489 and IEC 60947-2 standards. Those standards are worth confirming when you're matching a replacement breaker to the requirements of existing equipment or a particular installation.

Manufacturer information also includes REACH Article 33 documentation. RoHS substance-restriction compliance information and a SCIP number are listed as unavailable in the supplied product data, so those items shouldn't be assumed.

Where It Works Best

The HLMD63B500 makes the most sense where the equipment calls for its specific combination of specifications: 500 amps, three-pole, 600 VAC, an LMD frame, thermal-magnetic trip, and TA3K500 load lugs.

That makes it particularly relevant for maintenance and form, fit, and functional replacement in compatible commercial and industrial electrical equipment, including legacy installations built around this breaker configuration.
