HFD62B250L - 250Amp Circuit Breaker

HFD62B250L - 250Amp Circuit Breaker

The Siemens HFD62B250L is a 250A, 2-pole molded case circuit breaker for compatible SENTRON equipment that uses the FD frame. It’s rated up to 600VAC and uses a thermal-magnetic trip unit for overload and short-circuit protection. At 600V, the breaker carries a 25 kAIC interrupting rating, while at 480V it’s rated 65 kAIC. The HFD62B250L also comes with TA1FD350A lugs on both the line and load sides, which is an important detail when you’re matching an existing installation.

Material Compliance and Certifications

The HFD62B250L meets UL 489 and IEC 60947-2 standards. For anyone replacing a breaker in an existing system, those certifications are worth confirming along with the electrical ratings and physical fit.

Where It Works Best

The Siemens HFD62B250L is best suited to commercial and industrial electrical distribution equipment that specifically requires a 250A, 2-pole FD-frame molded case circuit breaker. It makes particular sense in maintenance and replacement situations where the existing system was designed around this breaker’s frame size, voltage rating, interrupting capacity, lug arrangement, and dimensions.
