HLD63B250L - 250Amp Circuit Breaker

HLD63B250L - 250Amp Circuit Breaker

The Siemens HLD63B250L is a 250-amp, 3-pole molded case circuit breaker in the SENTRON HLD6 family. Built around the LD frame, it uses a thermal-magnetic trip unit and is rated for your applications up to 600 VAC. Its interrupting capacity is 35 kAIC at 600V and 65 kAIC at 480V. This is a standard 40°C breaker supplied with TA2J6500 lugs on both the line and load sides, so the termination setup is already clearly defined. The lugs accept copper conductors from 3/0 AWG through 500 kcmil and aluminum conductors from 4/0 AWG through 500 kcmil.

Material Compliance and Certifications

The HLD63B250L meets UL 489 and IEC 60947-2 standards, two important specifications to consider when confirming a circuit breaker for a particular electrical system.

The manufacturer's product data also provides REACH Article 33 information. RoHS substance-restriction compliance information and the SCIP number are listed as not available. If either is required for a particular project or facility, it should be confirmed during the project's compliance review.

Where It Works Best

The HLD63B250L makes the most sense in electrical distribution applications that specifically call for a 250A, 3-pole LD-frame breaker with a thermal-magnetic trip unit and 600 VAC rating. It's also well suited to maintenance and replacement work involving equipment designed around this particular breaker configuration.

And that's where checking the details pays off. A breaker isn't a match simply because the amperage looks right. When replacing an existing unit, compare the catalog number, frame, pole count, voltage, interrupting rating, trip type, dimensions, lug configuration, conductor material, and allowable wire sizes with the equipment requirements.
