HLD63B600L - 600Amp Circuit Breaker

HLD63B600L - 600Amp Circuit Breaker

The Siemens HLD63B600L is a 600-amp, 3-pole SENTRON molded case circuit breaker built on the LD frame. It uses a thermal-magnetic trip unit and is rated for 600 VAC, with an interrupting capacity of 35 kAIC at 600V and 65 kAIC at 480V. This breaker comes assembled with TA2J6500 lugs on both the line and load sides, accepting 3/0 AWG through 500 kcmil copper conductors or 4/0 AWG through 500 kcmil aluminum conductors. It's a practical choice for your compatible commercial and industrial electrical equipment that requires this specific LD-frame configuration—a straightforward breaker built to last and designed to do the job it was intended for.

Material Compliance and Certifications

The HLD63B600L meets UL 489 and IEC 60947-2 standards. These are important references when confirming whether the breaker meets the requirements of a particular installation.

The manufacturer information also includes REACH Article 33 information for this product. RoHS substance-restriction compliance information and a SCIP number are listed as unavailable. Any project with specific material or environmental compliance requirements should be checked against the applicable product documentation.

Where It Works Best

The Siemens HLD63B600L makes the most sense in commercial and industrial electrical systems already designed for its specific combination of 600A capacity, three-pole, 600 VAC rating, LD frame, thermal-magnetic trip, and lug configuration. It's especially relevant when replacing an existing HLD63B600L and maintaining the original equipment's form, fit, and function are priorities.
