HLMXD63B800 - 800Amp Circuit Breaker

HLMXD63B800 - 800Amp Circuit Breaker

When you’re replacing a circuit breaker in an existing electrical system, the details matter. The Siemens HLMXD63B800 is an 800A, 3-pole molded case circuit breaker built on the LMD frame and rated for applications up to 600 VAC. The breaker measures 7.5 inches wide, 16 inches high, and 4.5 inches deep, giving maintenance teams and electricians concrete dimensions to work with when checking an existing installation. It also meets UL 489 and IEC 60947-2 standards. When those specifications match the application, the HLMXD63B800 provides the form, fit, and function needed for compatible electrical distribution equipment—and it’s built to last when properly selected and used within its ratings.

Key Features and Benefits

• 800A, 3-pole configuration: Designed for compatible electrical distribution equipment requiring an 800-amp, three-pole breaker.
• Rated up to 600 VAC: Suitable for systems calling for this specific voltage rating and breaker configuration.
• Thermal-magnetic protection: Uses a fixed, non-interchangeable thermal-magnetic trip unit.
• LMD frame: Helpful when matching the physical and electrical requirements of existing equipment.
• No lugs installed: An important detail when determining the correct terminal and conductor setup for the application.
• Recognized standards: Meets UL 489 and IEC 60947-2 requirements.

Where It Works Best

The Siemens HLMXD63B800 makes the most sense in commercial or industrial electrical equipment that specifically calls for an 800A, 3-pole, 600V LMD-frame circuit breaker with a fixed thermal-magnetic trip. It can be a practical choice for maintenance and replacement projects involving compatible existing or legacy equipment where maintaining the required form, fit, and electrical function is the main objective.
