HLMXD63B800L - 800A Circuit Breaker

HLMXD63B800L - 800A Circuit Breaker

The Siemens HLMXD63B800L is an 800-amp, 3-pole molded-case circuit breaker from the SENTRON HLMD6 family, designed for use with compatible low-voltage electrical distribution equipment. Built on the LMD frame, it combines a fixed, non-interchangeable thermal-magnetic trip unit with ratings of 50 kAIC at 600 VAC and 65 kAIC at 480 VAC. One detail that matters when you're matching a replacement is right in the catalog number: the HLMXD63B800L comes equipped with line- and load-side TA3K500 lugs, accepting 1/0 AWG through 500 kcmil copper or aluminum conductors. That can make identifying the correct configuration much more straightforward when the existing installation requires a lug-equipped breaker.

Key Features and Benefits

• 800A, 3-pole configuration: Provides the amperage and pole arrangement required by compatible three-phase electrical distribution applications.
• 600 VAC rating: Designed for installations requiring an LMD-frame breaker rated up to 600 VAC.
• Fixed thermal-magnetic trip: Uses a non-interchangeable thermal-magnetic trip unit for overcurrent protection within its specified application.
• Line and load lugs included: The TA3K500 lugs are installed on both sides of the breaker and accept copper or aluminum conductors from 1/0 AWG to 500 kcmil.
• LMD frame construction: Helps maintenance personnel verify physical and electrical compatibility when replacing an existing breaker in equipment designed for this frame.
• Published dimensions: The 7.5" W × 16" H × 4.5" D dimensions provide an important reference when checking physical fit.
• Recognized electrical standards: Meets UL 489 and IEC 60947-2 requirements.

Where It Works Best

The HLMXD63B800L is best suited to commercial and industrial electrical distribution applications, specifically designed for an 800A, 3-pole LMD-frame molded-case circuit breaker with a fixed thermal-magnetic trip and line- and load-side lugs. It is particularly relevant when maintaining existing or legacy equipment where matching the original breaker's form, fit, and function is the priority.
