LMD63B800L - 800Amp Circuit Breaker

LMD63B800L - 800Amp Circuit Breaker

The LMD63B800L provides several key details when matching a breaker to your existing equipment. It's an 800A, three-pole molded case circuit breaker built on an LMD frame, with a thermal-magnetic trip unit and a standard 40°C rating.

Key Features and Benefits

• 800A, three-pole configuration: Gives you two of the first specifications to compare when identifying the correct breaker for existing equipment.
• LMD frame: An important form-and-fit detail when matching the LMD63B800L to an existing installation.
• Thermal-magnetic trip unit: Uses the specified thermal-magnetic trip configuration.
• Line and load lugs included: Both sides include TA3K500 lugs, an important detail to confirm before installation.
• Copper or aluminum conductor compatibility: The supplied lugs accept 1/0 AWG through 500 kcmil Cu/Al conductors.
• Standard 40°C rating: Compare this specification with the application requirements and existing breaker.

Where It Works Best

The LMD63B800L 800A 3-pole molded case circuit breaker suits compatible existing and legacy electrical equipment that calls for an LMD-frame breaker with a thermal-magnetic trip unit and the same electrical and physical configuration. The included TA3K500 line and load lugs are particularly useful identifiers, especially where the existing connection calls for 1/0 AWG through 500 kcmil copper or aluminum conductors.
