HLD63B600 - 600Amp Circuit Breaker

HLD63B600 - 600Amp Circuit Breaker

When you’re replacing a circuit breaker in existing equipment, getting the details right matters. The Siemens HLD63B600 is a 600-amp, 3-pole SENTRON molded case circuit breaker built on the LD frame and equipped with a thermal-magnetic trip unit. Measuring 7.5 inches wide, 11 inches high, and 4 inches deep, the HLD63B600 has clearly defined dimensions that can be checked against the existing installation before replacement. It also meets UL 489 and IEC 60947-2 standards.

Key Features and Benefits

• 600A, 3-pole configuration for compatible three-phase electrical applications.
• Rated for 600 VAC, making it suitable for systems designed around this voltage and breaker configuration.
• Thermal-magnetic trip unit provides the specified trip characteristics for this LD-frame breaker.
• Includes TA2J6500 load-side lugs, so connection details can be matched to the existing installation.
• Accepts 3/0 AWG–500 kcmil copper and 4/0 AWG–500 kcmil aluminum conductors.
• Measures 7.5" W × 11" H × 4" D, an important consideration when confirming physical fit.
• Meets UL 489 and IEC 60947-2 standards.

Material Compliance and Certifications

The HLD63B600 meets UL 489 and IEC 60947-2 standards. These are important specifications to consider when matching a replacement breaker to the requirements of an existing electrical system.

The supplied manufacturer information also references REACH Article 33 information. RoHS substance-restriction compliance is listed as unavailable, and a SCIP number is not provided. If a project has specific material or environmental compliance requirements, those requirements should be checked against the applicable product documentation.

Where It Works Best

The HLD63B600 makes the most sense in commercial and industrial electrical systems that were designed to use a 600A, 3-pole, 600 VAC LD-frame molded case circuit breaker with the corresponding trip, interrupting, connection, and dimensional requirements. It can be especially useful for maintenance and replacement work where the goal is to keep the existing equipment configuration intact.

And this is where checking the full catalog number pays off. Two breakers can share the same amperage rating and still differ in frame size, interrupting rating, lug arrangement, dimensions, or other characteristics. When replacing an HLD63B600, verify the LD frame, three poles, 600A rating, 600 VAC rating, thermal-magnetic trip, interrupting capacity, TA2J6500 lugs, conductor range, and physical dimensions against the existing equipment.
