HLMXD63B500L - 500Amp Circuit Breaker

HLMXD63B500L - 500Amp Circuit Breaker

The Siemens HLMXD63B500L is a 500A, 3-pole SENTRON molded-case circuit breaker designed for your applications requiring an LMD-frame breaker rated up to 600 VAC. Built around a fixed, non-interchangeable thermal-magnetic trip unit, the HLMXD63B500L provides an interrupting rating of 50 kAIC at 600V and 65 kAIC at 480V. One detail that matters when identifying the correct replacement is the “L” configuration: this model comes with line and load lugs installed, helping distinguish it from otherwise similar LMD-frame breakers with different lug arrangements.

Key Features and Benefits

• 500A current rating: Designed for compatible electrical systems requiring a 500-amp molded case circuit breaker.
• 3-pole configuration: Provides the required three-pole arrangement for applicable three-phase electrical equipment.
• Rated up to 600 VAC: Suitable for installations designed around a breaker with a 600 VAC maximum voltage rating.
• LMD frame: Maintains the specific Siemens LMD-frame configuration required by compatible equipment.
• Fixed thermal-magnetic trip unit: Uses a non-interchangeable thermal-magnetic trip configuration suited to the breaker's original design.
• Line and load lugs installed: The HLMXD63B500L includes lugs on both the line and load sides, an important compatibility detail when identifying a replacement breaker.
• Defined physical footprint: Dimensions of 7.5" W × 16" H × 4.5" D make it easier to confirm physical fit with existing equipment.
• Recognized electrical standards: Meets UL 489 and IEC 60947-2 requirements.

Material Compliance and Certifications

The Siemens HLMXD63B500L circuit breaker meets UL 489 and IEC 60947-2, two important standards to consider when matching a breaker to the requirements of an existing electrical system. Manufacturer information also lists compliance with substance restrictions under the RoHS directive since July 14, 2008.

Where It Works Best

The HLMXD63B500L is best suited to commercial and industrial electrical applications specifically designed for a 500A, 3-pole Siemens LMD-frame molded case circuit breaker. It can be relevant when maintaining compatible switchgear, electrical distribution equipment, and other legacy assemblies where the existing system calls for this particular combination of electrical ratings, frame dimensions, trip characteristics, and lug configuration.
