HLMXD63B600 - 600Amp Circuit Breaker

HLMXD63B600 - 600Amp Circuit Breaker

When you’re replacing a breaker in an existing electrical system, getting the details right matters. The Siemens HLMXD63B600 is a 600A, 3-pole molded case circuit breaker from the SENTRON line, built around the LMD frame for compatible applications. It is rated for 600 VAC, with an interrupting capacity of 50 kAIC at 600V and 65 kAIC at 480V. Protection is provided by a fixed, non-interchangeable thermal-magnetic trip unit, and the breaker carries a standard 40°C rating. One detail worth noting before installation: the HLMXD63B600 comes without lugs installed. That makes it especially important to check the existing equipment and connection requirements rather than relying on amperage alone.

Key Features and Benefits

• 600A, 3-pole configuration for compatible three-phase electrical systems.
• Rated for operation at up to 600 VAC.
• Fixed thermal-magnetic trip unit provides the specified protection characteristics without an interchangeable trip.
• LMD-frame construction helps maintain proper form and fit in equipment designed for this breaker configuration.
• Supplied without lugs installed, an important consideration when matching an existing installation.
• Meets UL 489 and IEC 60947-2 standards.
• Clearly defined dimensions make it easier to confirm physical compatibility before installation.

Where It Works Best

The HLMXD63B600 makes the most sense in commercial and industrial electrical systems specifically designed around its LMD frame, 600A rating, three-pole configuration, and 600 VAC rating. It can be particularly useful when maintaining existing or legacy electrical equipment where changing the breaker's basic form or electrical characteristics isn't the objective.
