HLD63B250 - 250Amp Circuit Breaker

HLD63B250 - 250Amp Circuit Breaker

When you’re replacing a circuit breaker, getting the details right matters. The Siemens HLD63B250 is a 250A, 3-pole molded case circuit breaker from the LD frame family, built for low-voltage distribution applications requiring a 600 VAC rating and a thermal-magnetic trip unit.

Key Features and Benefits

• 250A, 3-pole configuration for compatible low-voltage distribution systems.
• Rated for 600 VAC applications.
• Uses a thermal-magnetic trip unit.
• Standard 40°C LD-frame breaker configuration.
• Includes TA2J6500 load-side lugs, so the specified connections are already part of the breaker configuration.
• Accepts both copper and aluminum conductors within the manufacturer's stated wire ranges.
• Meets UL 489 and IEC 60947-2 standards.

Material Compliance and Certifications

The Siemens HLD63B250 circuit breaker meets UL 489 and IEC 60947-2 standards, providing documented standards information that can be checked against the requirements of the intended installation.

Manufacturer data also identifies REACH Article 33 information for this product. The supplied specifications do not state compliance with RoHS substance restrictions or provide an SCIP number. Those items should therefore be verified separately if they're required for a particular facility, project, or compliance program.

Where It Works Best

The HLD63B250 makes the most sense for electrical distribution equipment that specifically requires—or is verified as compatible with—a 250A, 3-pole LD-frame molded-case circuit breaker with a 600 VAC rating and a thermal-magnetic trip. It's especially relevant for maintenance and replacement work, where the goal is to keep the correct form, fit, and function.

And this is where it's worth checking the details rather than stopping at “250 amps.” A proper replacement assessment should account for the catalog number, LD frame, three-pole configuration, voltage, interrupting rating, trip type, dimensions, lug configuration, conductor material, and wire size. The HLD63B250's TA2J6500 lugs handle 3/0 AWG through 500 kcmil copper and 4/0 AWG through 500 kcmil aluminum, providing concrete specifications for comparison with the existing installation.
