HLD63B500 - 500Amp Circuit Breaker

HLD63B500 - 500Amp Circuit Breaker

Finding the right replacement breaker comes down to matching the details, and the Siemens HLD63B500 gives you a clearly defined set of specifications to work with. This SENTRON molded case circuit breaker is a 500A, 3-pole LD-frame breaker rated for 600 VAC, with a thermal-magnetic trip unit and a standard 40°C rating. Its interrupting capacity is 35 kAIC at 600V and 65 kAIC at 480V. The breaker also includes TA2J6500 lugs on the load sides, accepting 3/0 AWG through 500 kcmil copper conductors and 4/0 AWG through 500 kcmil aluminum conductors. At 7.5 inches wide, 11 inches high, and 4 inches deep, the HLD63B500 has specific dimensions that can be checked against existing equipment before installation.

Key Features and Benefits

• 500A, 3-pole configuration – Made for compatible electrical distribution applications requiring these specific ratings.
• Rated for 600 VAC – Fits applications that call for a molded case circuit breaker with a 600 VAC rating.
• Thermal-magnetic trip unit – Provides the trip configuration specified for this SENTRON LD-frame breaker.
• Load lugs – TA2J6500 lugs are included on both sides, simplifying matching the connection arrangement.
• Copper and aluminum conductor ranges – Accepts 3/0 AWG–500 kcmil copper or 4/0 AWG–500 kcmil aluminum conductors.
• Easy-to-check dimensions – The 7.5" × 11" × 4" footprint gives maintenance personnel another key point to verify when replacing an existing breaker.

Material Compliance and Certifications

The HLD63B500 meets UL 489 and IEC 60947-2 standards, providing installers and maintenance teams with documented standards information to consider when assessing suitability for an existing application.

Manufacturer data also identifies REACH Article 33 information for this product. RoHS substance-restriction compliance information and a SCIP number are listed as unavailable, so no additional compliance claims should be assumed from the available specifications.

Where It Works Best

The HLD63B500 is best suited for maintenance and replacement jobs where an existing electrical system requires a 500A, 3-pole Siemens LD-frame molded-case circuit breaker with matching electrical and physical characteristics. It's a natural candidate for compatible commercial and industrial distribution equipment where maintaining the established form, fit, and function is the priority.
