HFD62B250 - 250Amp Circuit Breaker

HFD62B250 - 250Amp Circuit Breaker

The Siemens HFD62B250 is a 250A, 2-pole molded case circuit breaker from the SENTRON HFD6 family, designed for compatible electrical distribution equipment requiring an FD-frame breaker. Rated for systems up to 600VAC, it uses a thermal-magnetic trip unit to provide overload and short-circuit protection. The HFD62B250 carries an interrupting rating of 25 kAIC at 600V and 65 kAIC at 480V, making those ratings important checkpoints when matching the breaker to your existing application.

Key Features and Benefits

• 250A current rating supports compatible electrical systems requiring a 250-amp molded case circuit breaker.
• 2-pole configuration provides the specified arrangement for equipment designed around a two-pole FD-frame breaker.
• 600VAC maximum voltage rating makes it suitable for compatible applications operating within this voltage limit.
• Thermal-magnetic trip unit provides overload and short-circuit protection using a straightforward, established trip design.
• 25 kAIC at 600V and 65 kAIC at 480V provide clearly defined interrupting ratings for proper application matching.
• FD frame supports form, fit, and functional replacement in compatible SENTRON equipment designed for this frame.
• TA1FD350A load-side lugs accommodate a broad range of copper and aluminum conductor sizes.
• UL 489 and IEC 60947-2 compliance helps confirm the breaker against recognized product standards.
