HLMD63B800 - 800Amp Circuit Breaker

HLMD63B800 - 800Amp Circuit  Breaker

When you need a breaker that matches an existing LMD-frame application, the details matter. The Siemens HLMD63B800 is an 800A, 3-pole molded case circuit breaker from the SENTRON family, rated for 600 VAC and equipped with a thermal-magnetic trip unit. It carries an interrupting rating of 50 kAIC at 600V and 65 kAIC at 480V. For replacement and maintenance work, the HLMD63B800 is a practical choice when the application specifically calls for its combination of LMD frame, 800A rating, three-pole configuration, voltage, interrupting capacity, trip type, and lug arrangement. It also meets UL 489 and IEC 60947-2 standards. Simply put, this is a breaker built to last and built for applications where matching the original electrical and physical requirements matters.

Key Features and Benefits

• 800A, 3-pole configuration for systems designed around these specific electrical requirements.
• Thermal-magnetic trip unit provides the specified overcurrent protection characteristics.
• LMD frame helps simplify identification when matching an existing breaker or compatible equipment.
• TA3K500 load lugs are included.
• Accepts a broad 1/0 AWG to 500 kcmil conductor range.
• Lugs accommodate both copper and aluminum conductors.
• Clearly defined 7.5" × 16" × 4.5" footprint helps with form-and-fit verification.
• Meets UL 489 and IEC 60947-2 standards.

Material Compliance and Certifications

The HLMD63B800 meets UL 489 and IEC 60947-2 standards. Manufacturer information also provides REACH Article 33 documentation. RoHS substance-restriction compliance and a SCIP number are listed by the manufacturer as not available, while WEEE (2012/19/EU) take-back obligations are listed as No.

For an existing installation, certification is only part of the picture. The breaker should also be checked against the equipment's required frame, amperage, voltage, pole count, interrupting rating, trip characteristics, lug configuration, conductor size, and physical dimensions.

Where It Works Best

The Siemens HLMD63B800 makes the most sense for commercial and industrial electrical equipment designed for an 800A, 3-pole LMD-frame molded-case circuit breaker. It's especially relevant when maintaining an existing or legacy system where the goal is to preserve the required form, fit, and function rather than change the electrical design.
